1 How To Use This Manual 

This manual describes how to obtain and interpret the data products from the updated 1991–

2005 National Solar Radiation Database (NSRDB). This is an update of the original 1961–

1990 NSRDB released in 1992 (NREL 1995). 

Important 

Nearly all of the solar data in the original and updated versions of the 

NSRDB are modeled. The intent of the modeled data is to present hourly 

solar radiation values that, in the aggregate, possess statistical properties 

(e.g., means, standard deviations, and cumulative frequency distributions) 

that are as close as possible to the statistical properties of measured solar 

data over the period of a month or year. These data do not represent each 

specific hourly value of solar radiation to the same or equivalent accuracy 

as the long-term statistics. One must read sections 2.1.5, 2.2, and 2.3 to 

understand the content of the database and its applicability. 

1.1 Introduction 

In 2003, the National Renewable Energy Laboratory (NREL) investigated the feasibility of 

updating the NSRDB and began collaborative work with several agencies, including the 

National Aeronautics and Space Administration (NASA), the National Climatic Data Center 

(NCDC), the Northeast Regional Climate Center, the State University of New York at 

Albany (SUNY), the University of Oregon, the University of Wisconsin, and the private firm 

Solar Consulting Services (Wilcox 2004). 

The original NSRDB held a serially complete data set for all sun-up hours for 239 stations. 

Because of expected changes in the roster of National Weather Service (NWS) sites, as well 

as the potential for adding NSRDB sites, the updated list of stations was not restricted to 

those same 239. Instead, it included as many stations and as much data as possible to increase 

the usefulness of the data set. This update therefore provides data for 1,454 stations. 

In addition to the expanded station list, this update differs from the original NSRDB several 

ways. It contains: 

• New or modified solar models 

• New gridded data product 

• New station identification numbers 

• A new station classification scheme 

• New data formats 

• Different meteorological fields 

• Revised uncertainty estimates. 

 1
Each of these topics is discussed later. Users are encouraged to carefully consider the 

sections on modeled data and data uncertainty to better understand the applicability of the 

NSRDB for specific work.

1.1.1 New Models 

Nearly all of the solar data in the original NSRDB and this update were produced using solar 

radiation models. Less than 1% of the records in this update contain measured data. See the 

important note at the top of Page 1. 

The original NSRDB (NREL 1995) was produced using the Meteorological-Statistical 

(METSTAT) model (Maxwell 1998), which, in turn, was developed using NWS observations 

of total and opaque cloud cover and measured solar data from the SOLRAD (Solar 

Radiation) network. In the early 1990s, the NWS began supplementing or replacing its 

conventional manual weather observations with the Automated Surface Observing System 

(ASOS). For many aviation applications, the ASOS data are comparable with the manual 

observations. However, for some climatological applications, including solar radiation 

modeling, the manual and automatic cloud observations are not comparable, as discussed in 

this manual. Full sky total and opaque cloud cover observations from trained personnel were 

replaced with cloud estimates from ceilometers, which rely on a temporal evaluation of 

clouds passing directly above the instrument. The ceilometer has a 12,000-ft reach in altitude 

and can neither detect high clouds nor distinguish between total and opaque clouds. In 

addition, the resolution of the reported sky cover went from tenths or oktas to a coded 

scheme that at times yields only four values of sky cover (i.e., clear, scattered, broken, and 

overcast). This compares with eleven values for units of tenths (0–10 tenths) or nine for units 

of oktas (0–8 oktas). 

To compensate for this change, NCDC’s ASOS Cloud Data Set (Graumann 2003), also 

called the ASOS Supplemental Cloud Product, was used to derive cloud cover values 

compatible with the METSTAT model. The Supplemental Cloud Product uses satellite 

imagery for total cloud cover estimates that include cloud height information. From this, total 

and opaque cloud estimates were developed in tenths, with cloud height distinguishing 

between them (Wilcox 2005). (Opaque clouds predominantly occur at lower heights.) See 

Section 2.1.2. 

In addition to the NREL METSTAT model, SUNY developed a model that uses 

Geostationary Operational Environmental Satellite (GOES) imagery to estimate solar 

radiation. In simple terms, this satellite model uses the inverse relationship between reflected 

irradiance (that reflected by clouds and atmosphere back to space and the satellite sensor) and 

ground irradiance (that transmitted through the atmosphere to the Earth’s surface). In modelevaluation work conducted as part of the NSRDB project, this satellite model proved 

comparable with meteorological-based models. (The project also evaluated a model from the 

Northeast Regional Climate Center that uses ASOS data. It was also found comparable with 

other models; however, the METSTAT meteorological-based model was chosen because of 

its NSRDB legacy.) 

 2
Based on simplicity and consistency, the SUNY model would have replaced the METSTAT 

model but for its limited period of record. GOES imagery for the project was archived 

starting in 1998, leaving the period of 1991–1997 without coverage. Hence, a hybrid 

production effort that uses both models was designed. (The distribution of model data is 

explained in Section 1.1.5) 

1.1.2 New Gridded Data Product 

This update not only contains far more stations than the original NSRDB but also introduces 

a new product in the form of a 10-km gridded database. One very attractive feature of the 

SUNY model is its ability to create a high-resolution gridded data set (Perez 2002). Whereas 

the METSTAT model relies on scattered and sometimes sparse point-source ground 

meteorological observations, the SUNY model runs on the virtually seamless GOES satellite 

images. Although GOES images provide up to 1-km resolution, in the SUNY model, these 

data are down-sampled to 10-km resolution (0.1 ̊ x 0.1 ̊). This resolution is adequate for most 

solar radiation resource applications and represents a practical trade-off between resolution 

and processing and data storage considerations. The model uses both GOES-East and GOESWest satellites for the best coverage of the United States. 

The SUNY model produces estimates of global and direct irradiance at hourly intervals on 

the 10-km grid for all 50 states, excluding Alaska above 60 ̊ north latitude and west of 160 ̊

west longitude, where the geostationary satellites cannot resolve cloud cover with necessary 

detail. SUNY model diffuse values were derived from the global and direct irradiance values 

for each grid cell as the difference between the global and vertical component of the direct. 

The hourly NSRDB records hold hour-ending irradiance values that represent an integration 

of the previous hour’s irradiance. GOES satellite imagery is a snapshot of the earth disk, and, 

hence, the irradiance values in the SUNY model grid represent an instant in time rather than 

an integrated value. Further, the GOES-West satellite images are produced on the hour, and 

the GOES-East images are produced at 15 minutes past the hour. To make the SUNY model 

data conform to the NSRDB time convention, its data were shifted in time to better represent 

the characteristics of hourly-integrated values (see Section 2.1.6). This approach also allows 

the gridded data to be used for existing applications that expect a top-of-hour timestamp. 

Note: Because the SUNY model derives solar radiation measurements from image brightness 

data and (averaged) ancillary data, it represents a “snapshot” solar radiation value for a 

particular hour that may be significantly different from METSTAT data, which is based on 

estimates from meteorological data and the attendant statistical modifications included in the 

METSTAT model, particularly under variable atmospheric conditions. Source flags for the 

solar radiation modeled data indicate the source of the estimated solar radiation data. See 

sections 2.1.6, 2.3.5, 2.3.6.4, and 2.3.6.5. 

1.1.3 New Station Identification Numbers 

Station identification numbers in the 1961–1990 NSRDB were based on the five-digit 

Weather Bureau Army Navy (WBAN) numbering scheme, which was used by NCDC at the 

time for its station list. Since then, NCDC began using the six-digit United States Air Force 

(USAF) numbering system in addition to the WBAN system, and to conform, the NSRDB 

 3
also uses the USAF scheme. Appendix A lists all stations and identifiers ordered 

alphabetically by state and site name, along with site location information. Table A-1 lists all 

sites ordered by USAF identifier. Appendix B provides a translation from the WBAN 

numbers of the 239 stations in the 1961–1990 NSRDB to their equivalent USAF identifiers 

in this 1991–2005 update. 

1.1.4 New Station Classification Scheme 

The 1961–1990 NSRDB had two station classifications: primary and secondary, so 

designated by whether the station’s data included measured (versus modeled) solar radiation 

values. Fifty-six sites were designated as primary; the rest (183) were secondary. 

For the 1991–2005 NSRDB update, that classification method was dropped and replaced 

with a classification based on data quality and completeness (see Section 2.3.7). Further, the 

original NSRDB convention of merging measured data with modeled data when it was 

available was dropped in favor of separate fields for measured and modeled data. This 

decision hinged on differences between measured and modeled data. The nature of solar 

energy measurements often results in values slightly or even grossly inconsistent among 

coupled parameters, and measured data sets are rarely serially complete. This fact results in 

an impossibly complex circumstance of sorting out which parameters are correct and which 

are in error and how to bring parameters into compliance. Modeled data, on the other hand, 

cannot accurately reproduce a variable solar time series required by some system 

performance applications. (This is because of a lack of definitive information about the 

spatial relationship among the sun, clouds, and a ground observer—in other words, whether 

any clouds in a one-dimensional sky cover observation are occluding the sun). Thus, the two 

sets of output fields afford users the consistency of modeled data while accommodating 

applications that demand measured data. 

The Supplemental Cloud Product used for more accurate cloud estimates as described above 

is complete neither in time nor space for the 15-year update period. That and other variations 

in cloud observations, and the use of the SUNY satellite model output where and when it was 

available, led to different levels of uncertainty in the modeled data. From this, the three-class 

scheme for categorizing sites was developed to best convey to users variations in the quality 

of data. This scheme is detailed in Section 2.3.7. 

Although 40 stations include some measured solar data (though none with a complete period 

of record), the inclusion of measured data is not a factor in the new station classification. 

Stations in all three classifications may include measured data. See Appendix C for a list of 

stations with measured solar data and the instrumentation used for measurements. 

Figure 1 shows the distribution of the NSRDB update sites by class and includes the 

locations of the 1961–1990 NSRDB sites.

with 1961–1990 NSRDB stations 

1.1.5 New Data Formats 

The 1961–1990 NSRDB was distributed in two formats: the NSRDB Synoptic format (used in 

the NCDC Solar and Meteorological Observation Network, or SAMSON, disks) and the 

NCDC TD3282 format. Because of immense changes in data distribution methods and 

efficiencies since the first release in 1992, NCDC will be distributing the data via the Internet. 

The updated NSRDB also will be distributed in a truncated format without the 

meteorological fields by NREL. This was necessary for users to have access to the solar data 

without cost. NCDC mandates that the meteorological data be distributed by it according to 

its fee schedule, whether it is in its Integrated Surface Hourly (ISH) format or incorporated 

into another product, such as the NSRDB. However, NCDC does not restrict the distribution 

of products derived from the ISH data, such as the solar data fields in the NSRDB. 

To respect these restrictions and strike a compromise between simplicity and a broader 

spectrum of data, the NCDC data set includes a single set of modeled output fields (global, 

direct, and diffuse, which can be from the SUNY model, or, if not available, the METSTAT 

model) as well as the measured solar fields. The NREL data set includes separate fields for 

METSTAT and SUNY modeled data, clear sky modeled values, and the measured data. The 

NREL data set also includes some ancillary data fields, such as those used for deriving 

aerosols, water vapor, and ground albedo. The new 10-km gridded solar product is 

distributed by NCDC at no cost. (This product does not contain any meteorological data.) 

 5
The solar data portion of the NSRDB will have free access from NCDC for all users via file 

transfer protocol. Free access will not include the meteorological parameters that are included 

in the ISH data set. ISH is one of the National Oceanic and Atmospheric Administration data 

sets that requires payment for user domains other than .gov, .edu, .mil, or .k12. 

See Section 1.3.3 for a summary of the data availability options. 

1.1.6 Different Meteorological Fields 

Relative to the 1961–1990 NSRDB, one measurement pair was added to NSRDB update 

records, and three were removed. 

 

• A pair of fields for liquid precipitation was added. This measurement was not in the 

original NSRDB but was subsequently added to the NCDC SAMSON data set as 

hourly values. This measurement is included in the updated NSRDB as two fields of 

magnitude and time, according to the ISH convention. 

• Snow cover and days since last snowfall were removed from the update because of a 

lack of consistent snow cover data in the ISH data set. These parameters were used to 

modify the albedo input to the METSTAT model during periods of snow cover. 

However, the new ground albedo data sets used for the update include the effects of 

snow (although based on climatological monthly averages rather than daily 

resolution). 

• The present weather field was removed. This field was originally used by the 

METSTAT model to modify the multiple-reflectance algorithm. The model has 

subsequently been modified to use ceiling height for this purpose. 

1.1.7 Revised Uncertainty Estimates 

The uncertainty estimates in the 1961–1990 NSRDB were based on the uncertainties of the 

input data sets. In the updated 1991–2005 NSRDB, base uncertainty estimates are founded in 

model evaluation results that use high-quality model input data and compare the model output 

with measured data. This base uncertainty was then modified for the increased uncertainty of 

filled or the ASOS data when such input data were used. With the SUNY model, a base 

uncertainty was similarly determined in the model evaluation and then increased for periods of 

snow cover or high latitude—circumstances known to degrade model performance. 

From even the early stages of planning, the uncertainty of the 1991–2005 NSRDB was 

expected to be greater than that of the 1961–1990 NSRDB because of changes in cloud 

observations that reduced the accuracy of the cloud estimates. A critical part of the 

production plan was to conspicuously include realistic estimates of data uncertainty in the 

data to afford users the opportunity to evaluate the applicability of the database to any 

application or pass through uncertainties to derivative data sets. Hourly uncertainties for 

modeled data range from 8% under optimal conditions to more than 25% for less-thanoptimal input data. 

 6
The METSTAT model, and to a lesser extent the SUNY model, can have hourly uncertainties 

that far exceed even the extreme uncertainties quoted above. This follows from a lack of 

information about the spatial relation among the sun, clouds, and a target measurement on the 

ground. For example, a cloud amount of 50% does not convey whether the sun is fully visible 

between scattered clouds or is entirely blocked by a cloud. However, the uncertainty should 

be in the context of the model’s design objective of reproducing the statistical characteristics 

of a solar data set rather than any specific hourly value. As stated in the 1961–1990 NSRDB 

user’s manual: 

Given this objective, the assignment of uncertainties with reference to the true 

solar radiation for specific hours would not provide the user with useful 

information. It was decided, therefore, that the uncertainty of individual 

hourly values estimated by METSTAT should be interpreted to mean that the 

true mean of measured hourly values under fixed atmospheric conditions lies 

within the range established by the estimated mean plus or minus the 

uncertainty, 95% of the time. (NREL 1993) 

This observation underscores model evaluation findings that the modeled data may have 

large root mean square (RMS) errors relative to measured data but much smaller bias errors. 

This also indicates that NSRDB-modeled data may introduce unexpected errors if used for 

applications that require accurate hourly tracking of true solar irradiance, such as 

photovoltaic system performance analyses. This caveat is less critical under cloudless (0% 

cloud cover) or completely overcast (100% cloud cover) conditions, in which a cloud 

observation leaves no ambiguity. However, even under these conditions, other atmospheric 

constituents (particularly aerosols, see Section 2.2.1.2) or varying cloud opacity can have 

significant effects on the measured irradiance values. 

1.2 How To Use and Interpret Database Products 

The NSRDB 1991–2005 update is a serially complete collection of hourly values of the three 

most common measurements of solar radiation (i.e., global horizontal, direct normal, and 

diffuse horizontal) over a period of time adequate to establish means and extremes and at a 

sufficient number or locations to represent regional solar radiation climates. Nearly all of the 

solar data in the NSRDB are modeled, and only 40 sites have measured solar data—none of 

them with a complete period of record (see Appendix C). 

The updated NSRDB will be distributed in three formats: two distributed by NCDC and the 

other by NREL. (See the discussion under Section 1.1.5). The solar radiation and 

meteorological elements in the NCDC data sets are listed in tables 1 and 3. The data elements 

distributed in the NREL data set are listed in Table 2

The 1991–2005 NSRDB contains data for 1,454 sites, which are subdivided into three classes 

of stations. 

 7
• Class I Stations have a complete period of record (all hours 1991–2005) for solar and 

key meteorological fields and have the highest-quality solar modeled data (221 sites). 

• Class II Stations have a complete period of record but significant periods of 

interpolated, filled, or otherwise lower-quality input data for the solar models (637 

sites). 

• Class III Stations have some gaps in the period of record but have at least 3 years of 

data that might be useful for some applications (596 sites). 

Note: Completeness in period of record for station classification is based on solar, 

dry-bulb, and dew-point temperatures; humidity; wind and wind direction; aerosol 

optical depth (AOD); precipitable water; and station pressure. Other fields in Class I 

and II stations may not be serially complete. 

Because of the data-filling methods used to accomplish the goal of serial completeness, 

NSRDB meteorological data may not be suitable for climatological work. The meteorological 

fields in the NSRDB should be used only as ancillary data for solar deployment and sizing 

applications. Filled/interpolated meteorological data should not be used for climatic 

applications. (All such data are flagged.) ISH data is better for such applications and is 

available at http://cdo.ncdc.noaa.gov. 

See Section 2.3.7 for the method used to assign station classifications. The stations and their 

classifications are listed in Appendix A, along with plots that show the proportion of 

modeled solar data by year and the amount of measured solar data included in a station’s data 

set. Appendix C lists sites that include measured solar radiation data. 

International systems (SI) units are used for all elements in the database except for 

atmospheric pressure. Atmospheric pressure is reported in millibars because these units are 

commonly used in computer models to estimate solar radiation and are consistent with 

standard NWS reporting practices. However, one millibar is equivalent to one hecto pascal, 

which is an SI unit. 

All data are referenced to local standard time according to the United States official time 

zone descriptions (Shanks 1996). The solar radiation elements represent radiant energy 

integrated over the hour preceding the designated time. Meteorological elements are values 

observed at or near the designated time. 

The goal of the updated NSRDB is to provide users with accurate, reliable, and up-to-date 

solar resource information to support the objective of national energy independence. The 

need for an update arose from several considerations: 

 8
• Most recent resource data best represent future conditions. 

• The original NSRDB is out of date by more than a decade and a half. 

• Interannual and interdecadal variability and trends are of increasing importance to 

industry, which requires continuous updating of records. 

• There were numerous requests for an update. 

• Quality and completeness of information needs to grow along with a growing 

industry. 

In addition, improvements in modeling and the potential for a high-resolution gridded data 

set provided practical incentives to invest in an update. The uncertainties of interpolating 

between sometimes sparse ground stations in the original NSRDB left a void for many solar 

resource assessment applications. 

Although growing interest in climate trends also provided impetus for an update, the 

uncertainties in the modeled solar data likely make the data inadequate to discern the small 

annual or even decadal changes caused by climate change. The measured solar data, if at 

sites with sufficient quantity and quality, may offer value for climate change research. (See 

Appendix C for station instrumentation and period-of-record information). 

1.3 Database Product Options 

Current products available for the NSRDB 1991–2005 update are described here. These 

products are intended to meet the needs of most solar resource assessment applications. 

Product options include: 

• Serial hourly data in three formats (one of which is an hourly gridded product) 

• Hourly, daily, and persistence summary products for solar radiation and several 

meteorological elements (Class I and II stations only). 

1.3.1 Hourly Data 

The serially complete hourly data provided in the NSRDB update are distributed in three 

formats available from two sources: 

• NCDC data sets 

NCDC distributes a ground-based solar and meteorological data set with fields most 

useful for general solar resource assessment. A general solar-only subset of this data 

set is also distributed by NCDC, as is the 10-km gridded data set produced by the 

SUNY model. The solar fields will also be added to the NCDC Climate Data Online 

service to be merged with existing meteorological data (but without the data filling). 

• NREL data set 

NREL distributes a research solar radiation data set that includes a superset of fields 

related to solar radiation (i.e., both ground-based and satellite-based solar radiation 

estimates) but no meteorological data. (See the discussion under Section 1.1.5.) 

 9
Format descriptions are located in sections 1.4.1 to 1.4.3. 

1.3.2 Statistical Summaries 

The NSRDB update contains statistical summaries computed from the hourly data for the 

entire period of record for Class I and II stations. Gaps in the record for Class III stations 

make a statistical comparison of those stations inconsistent with the other two classes of 

stations and prevents the provision of statistical summaries for Class III sites. For the solar 

radiation data, these statistics include the average and standard deviation of the daily total 

solar energy (direct normal, diffuse horizontal, and global horizontal) for each station-yearmonth and each station-year. The 15-year averages and the standard deviations of monthly 

and annual means from 1991–2005 are also provided. For the meteorological elements, only 

monthly, annual, and 15-year averages were computed. Future work includes a merging of 

the old and updated NSRDBs for 30-year statistical summaries (for those sites with an 

appropriate period of record). 

The hourly statistical product includes monthly, annual, and 15-year averages and standard 

deviations for each hour of the day for global horizontal, direct normal, and diffuse 

horizontal solar radiation. The averages can be used to prepare average diurnal profiles of 

hourly solar energy. The hourly values have also been binned in 24 50-Wh/m2

 bins from 0 to 

1,200 Wh/m2. The mean number of hourly values falling into each bin has been determined 

for each station-month for the 15-year period of record from 1991–2005. These statistics can 

be used to plot histograms and determine cumulative frequency distributions. 

A solar radiation persistence product exists for each station-month by calculating the number 

of times the daily total solar radiation energy persisted above or below set thresholds for 

periods from 1 to 15 days. These calculations were performed for the entire 15-year period 

1991–2005. 

The 1961–1990 NSRDB also included quality summary files, which are not reproduced for 

the 1991–2005 NSRDB update. Instead, a quality summary with additional information for 

each site in the NSRDB update is included in Appendix A, where plots indicate the relative 

quality of a site’s data for each year.

Figure 2 is an example of a daily statistics file. The header identifies the station using the sixdigit USAF identifier, station name (the first 22 characters), and state code. The header 

identifies the time zone (TZ) for the station as the number of hours by which the local 

standard time lags (minus) or leads (plus) Universal Time (e.g., Eastern Standard Time is 

designated as -5). Latitude and longitude for the station are given in degrees and minutes, 

station elevation is in meters, and the mean atmospheric pressure is given in millibars. 

 19
The next line in each file identifies the year(s) for which the next section of data applies. In 

each file, the first group of data provides daily statistics for the 15 years 1991–2005. 

Statistics for each year for the entire period of record follow. As an example, Figure 2 gives 

15-year statistics for Albuquerque, New Mexico. Monthly and annual statistics are given for 

1991 to 2005, followed by similar monthly statistics for each year. The Fortran formats for 

reading the header, year(s), and data records are given at the bottom of Figure 2. 

The standard deviations of solar radiation elements (e.g., SDGLO) for individual years and 

for the period of record (1991–2005) are not the same. For individual years, the standard 

deviations provide a measure of daily variability. For the period of record, the standard 

deviations provide a measure of the interannual variability of monthly and annual averages. 

The NSRDB mean values for meteorological elements may not be identical to the means 

published by NCDC. Small differences are expected as the result of different computational 

methods and differences in methods to replace missing data, but these differences have not 

been quantified. 

Two flags define the quality of each solar radiation element in the daily statistics files. The 

first flag gives the user information about the source of each hourly value for each solar 

radiation element, including the methods and input data used to derive model estimates. The 

flags are based on the hourly data and, in this context, represent the dominant category of 

source data for the period. Solar radiation source flags are defined in Table 5. The flags are 

ranked roughly from the highest- to the lowest-quality data. The first eight table entries (flags 

A–H) pertain to the 1961–1990 NSRDB and do not occur in the 1991–2005 update but are 

included here for historical completeness. Entries I–K (in bold) were added to denote the 

improved aerosol estimates used for the NSRDB update.

J Modeled solar radiation data using filled sky cover and revised aerosols 

K Modeled solar radiation data using satellite imagery and revised aerosols 

? Source does not fit any of the above categories. 

The second flag designates the uncertainty attached to the value. Uncertainty, as used here, 

provides an estimate of the interval around a measured or modeled value within which the 

true value will fall 95% of the time. The flags are based on the individual hourly data and, in 

this context, represent the average uncertainty for the period. The uncertainty flags are 

defined in Table 6.

1.4.4.2 Hourly Means, Standard Deviations, and Distributions 

The hourly statistics are presented in the form of means and standard deviations of the hourly 

values for each hour (from which diurnal profiles can be formed) and distributions generated 

by binning hourly values to determine the number of hours for which the radiation fell within 

24 50-Wh/m2 ranges (e.g., 0–50, 50–100, 100–150, ... 1100–1150, 1150–1200). The bin data 

have been normalized to indicate the percentage (in tenths) of all daytime hours for which the 

radiation fell within each bin. Figure 3 provides an example of these hourly statistics. The 

header information is the same as that used for the daily statistics, except that the year(s) 

represented by each file has been added as the last field of the header. 

Following the header, the next record identifies the solar radiation element (e.g., global 

horizontal radiation in Wh/m2) and the statistics (e.g., arithmetic means) for which the 

following data records apply. Each file contains data for all three solar radiation elements and 

each of the three statistics, as indicated in Figure 3. 

The first two fields in each data record designate the month (13 indicates annual statistics) 

and the source and uncertainty flags that apply to each monthly profile and distribution. 

The data fields for means and standard deviations contain these hourly statistics in Wh/m2 for 

each of the 24 hours of the day. For example, values for hour 01 represent the mean or 

standard deviation of the total radiant energy measured from midnight (2400) to 1 a.m. 

(0100). The data fields for the distributions designate the percentage of hours, in tenths of 

one percent, for which the average radiation fell within the 50-Wh/m2

 bins described above. 

The Fortran formats for reading the header, statistic identification, and data records are given 

at the bottom of Figure 3. 

1.4.4.3 Daily Persistence Data 

The persistence of weather events and the effect this has on the availability of solar radiation 

energy can affect many solar energy applications. In particular, the persistence of solar 

energy can affect energy storage requirements and the need for backup energy sources. 

The persistence statistic calculated for the NSRDB is the number of sequential days (runs) in 

a month during which the daily total energy exceeded or fell below 12 energy thresholds (see 

Figure 4). The run lengths vary from 1 to 15 or more days. The total number of runs over the 

entire 15-year period of 1991–2005 was determined for each month. The decision to compute 

persistence on a monthly (rather than perpetual) basis resulted in the truncation of runs at the 

end of each month and, possibly, in an underestimation of longer runs. Although this 

procedure caused some distortion of the statistics, it provided important information about 

seasonal changes in persistence. 

An example of the persistence statistic is shown in Figure 4. The thresholds for diffuse 

horizontal radiation (0–5,000 Wh/m2

 in 11 steps) are one-half those used for global 

horizontal and direct normal radiation (0–10,000 Wh/m2 in 11 steps). The header information 

gives the USAF number, station name, state code, month, and solar radiation element. 

 22
Each number in the matrices on the left of Figure 4 is the number of times the daily total 

solar energy exceeded the threshold indicated for that row for no more or no less than the 

number of days indicated for that column. Each number in the matrices on the right is the 

number of times the daily total solar energy was less than the threshold indicated for that row 

for no more or no less than the number of days indicated for that column. 

The numbers in these matrices can be used various ways. For example, the sum of all the 

numbers in the sector enclosed by the dotted line indicates that the daily total global 

horizontal energy fell below 6,000 Wh/m2

 for 4 or more days 27 times (the sum of all 

numbers in the sector) during 1991–2005. These matrices can be sectored in any manner that 

produces information useful to specific applications. 

The Fortran formats for reading the headers, number of days, thresholds, and number of 

events are given at the bottom of Figure 4. 

1.4.5 Hourly Quality Flags 

Quality flags are attached to each hourly solar radiation and meteorological element. Each 

solar radiation element has a source flag and an uncertainty value, and each meteorological 

element has a source flag. These flags provide information about the source and uncertainty 

of a data element to allow users to evaluate its usefulness. The flags are further described in 

the following sections. 

1.4.5.1 Source Flags, Quality Flags, and Estimated Uncertainty for Solar Radiation 

Elements 

For the modeled solar elements, the source flags are described in Table 7. 

Table 7. Modeled Solar Radiation Source Flags 

Flag Description 

1 Value modeled from the METSTAT model 

2 Value time-shifted from SUNY satellite model 

3 Value time-shifted from SUNY satellite model, adjusted to a minimum low-diffuse envelope 

(see Section 2.1.6) 

99 Missing data (associated data field is filled with -9900) 

The uncertainty flags (±%) are based on model type and quality of input data. The 

uncertainty is calculated based on model evaluation (Myers 2005) that compared predictions 

with measured ground data. The approach is based on the International Bureau of Weights 

and Measures and ISO GUM (International Bureau of Weights and Measures 1993). From 

this evaluation, an optimal uncertainty, Uopt, for each parameter was calculated using the best 

available sky cover or satellite image input data. 

 23
Uopt = (Umeas2

 + Umod

)

 1/2 (±%) 

where 

 – Umeas is the uncertainty of the measured data (±%) 

 – Umod is the RMSE of the model (±%) 

 – Ubias is the mean bias error of the model (±%). 

Umeas (±%) is set as follows: 

Global Direct Diffuse 

6 5 6 

These values are approximately double the ideal measurement uncertainty for the 

instrumentation and include additional uncertainties attributable to common operational 

problems at even well-maintained sites. 

Umod and Ubias (±%) for each model and parameter are listed below.

These optimal uncertainties reflect model performance using the highest quality input cloud 

data and include the uncertainty of the ground measurements. For the METSTAT model, 

optimal cloud cover consists of a set of total and opaque cloud values derived using the 

NCDC Supplemental Cloud Product. Manual cloud observations, when available, are 

presumed to be as good or better than those derived from the Supplemental Cloud Product 

but were not used in the model evaluation. For the SUNY model, optimal inputs are GOES 

pixels without snow cover and below 50 ̊ latitude. 

To these optimal uncertainties, more uncertainty is added for an uncertainty, U, under nonoptimal conditions.

Ground snow cover 5 High ground albedo compresses the dynamic range of 

the model. Periods of snow cover were estimated for 5 ̊

latitude and longitude cells on a monthly basis using 

snow cover probability contours for the United States 

(Dickerson 1967). If the probability of snow for a given 

location was greater than 25%, the additional 

uncertainty was added to the data. 

High latitude 10 Above 50 ̊ (arbitrarily set to affect only Alaska sites), 

cloud observations are compressed by angle of 

incidence and curvature of the earth as seen from the 

geostationary GOES satellite. (The model does not 

produce data for locations above 60 ̊ latitude.) 

For the measured solar radiation fields, the flag fields hold SERI-QC flags (NREL 1993). A 

brief summary of the SERI-QC flags appears in Table 10. 

 25
Table 10. SERI-QC Flag Descriptions 

 Flag Description 

00 Untested (raw data) 

01 Passed one-component test; data fall within min-max limits of Kt, Kn, or Kd

02 Passed two-component test; data fall within 0.03 of the Gompertz boundaries 

03 Passed three-component test; data come within 0.03 of satisfying 

 Kt = Kn + Kd

04 Passed visual inspection; not used by SERI-QC 

05 Failed visual inspection; not used by SERI-QC 

06 Value estimated; passes all pertinent SERI-QC test 

07 Failed one-component test; lower than allowed minimum 

08 Failed one-component test; higher than allowed maximum 

09 Passed three-component test but failed two-component test by >0.05 

10-93 Failed two- or three-component tests in one of four ways. 

 To determine the test failed and the manner of failure (high or low), 

 examine the remainder of the calculation (flag + 2)/4. 

 REM Failure 

 0 Parameter too low by three-component test (Kt = Kn + Kd) 

 1 Parameter too high by three-component test (Kt = Kn + Kd) 

 2 Parameter too low by two-component test (Gompertz boundaries) 

 3 Parameter too high by two-component test (Gompertz boundaries) 

 The magnitude of the test failure (distance in K-units) is determined from: 

 d = (INT (flag +2)/4)/100. 

94-97 Data fall into a physically impossible region where Kn > Kt by K-space distances of 

 0.05–0.10 (94), 0.10–0.15 (95), 0.15–0.20 (96), or ±0.20 (97). 

98 Not used 

99 Missing data (associated data field is filled with -9900) 

SERI-QC flags of 6 were used when filling a missing solar value using two other solar 

components. The quality of these data can be estimated from the SERI-QC flag of either of 

the other two components. 

Note: No effort was made to filter the measured data based on quality to allow the user the 

opportunity to optimize the data set according to quality specifications demanded by a 

particular application. 

 26
1.4.5.2 Quality Flags for Meteorological and Other Elements 

Meteorological data came from NCDC’s ISH data (Lott 2001). The flags that accompanied 

the ISH data were carried through to the NSRDB data fields (NCDC 2004). If a value was 

modified or filled, additional flags specific to the NSRDB data set were added. Table 11

describes flags on the meteorological data. 

Table 11. Meteorological Data Flags 

Flag Description 

0-9 ISH data flags (unmodified data) 

51 Value from short-term data filling or interpolation 

52 Value from medium-term data filling 

53 Value from long-term data filling 

54 Value is calculated: 

• Relative humidity calculated from dry-bulb and dew-point temperatures 

• Station pressure calculated from sea level pressure, altimeter, and dry-bulb 

• Data point undefined by convention (e.g., wind direction at zero speed) 

55 Value from last-ditch data filling 

56 Value statistically derived (cloud amounts based on probability tables) 

61 Value modeled (total and opaque cloud derived from Supplemental Cloud Product; ceiling 

height as linear function of opaque cloud amount) 

99 Value missing (associated data field is filled with -9900) 

The flags attached to the aerosol optical depth data are described in Table 12.

2 How the 1991–2005 NSRDB Update Was Produced 

2.1 Update History 

In 1992, NREL released the 1961–1990 NSRDB, a 30-year data set of measured and modeled 

solar radiation and accompanying meteorological data with solar estimates based on the 

METSTAT solar radiation model, also developed at NREL. In recent years, interest has 

grown in a NSRDB update that includes the decade of the 1990s and, possibly, beyond. 

In April 2003, NREL convened a meeting of experts to investigate the feasibility and 

desirability of an NSRDB update. Meeting participants concluded that the greatest challenge 

was a change in the measurements of cloud cover by the NWS. During the 1990s, the NWS 

migrated from a manual (human) system of full-sky cloud observations to the ASOS, which 

derives cloud cover from laser ceilometer observations at the zenith. The ASOS cloud 

observations are not compatible with the necessary inputs for the METSTAT model, which 

makes it impossible to create an updated NSRDB by simple METSTAT model runs using 

currently available meteorological data. 

Meeting participants agreed that an update was desirable to provide constituents with the most 

recent climatology and, possibly, a data set with enhanced spatial resolution. Recent advances 

in satellite-based techniques for modeling solar irradiance and cloud algorithms provided 

further incentive. 

2.1.1 Update Planning 

From the 2003 meeting of experts came a multi-stage plan, and collaborative work began with 

several agencies, including the National Aeronautics and Space Administration, the NCDC, 

the Northeast Regional Climate Center, SUNY, the University of Oregon, the University of 

Wisconsin, and the private firm Solar Consulting Services. The first stage produced a smallscale evaluation database that enabled the investigation of database production issues, the 

assessment of input data availability and quality, and the development modeling alternatives. 

From this evaluation came a full-scale plan for a multi-year update. 

Among the issues that needed to be resolved were: 

• Cloud cover observations 

• Aerosols, water vapor, and ozone 

• A ground-measured evaluation data set 

• Solar model selection 

• Satellite-based modeled irradiance data. 

2.1.2 Cloud Cover Observations 

The difficulty of changing from manual to automated cloud observations in the 1990s was 

exacerbated by significant changes in the operation of several solar radiation networks during 

the same period. This removed a consistent reference for studying the effects of changing 

inputs to solar models. Although the changes from manual to automated cloud observations 

were well supported by cost savings and exploitation of new technology, the effect on solar 

modelers—particularly in this project—has been a large discontinuity in the cloud observation 

 32
data record and consistency. (In addition, cloud reporting since the ASOS deployment has 

been found to be inconsistent from station to station because of the use of augmented humanbased observation at several sites.) 

As previously discussed, the recent switch to automatic weather stations eliminated the humanobserved total and opaque sky cover amounts used for inputs to the METSTAT model. The 

approach devised for the NSRDB update derived equivalent sky cover inputs (total and opaque 

cloud cover) for use with the METSTAT model from a combination of ASOS data and the 

NCDC ASOS Supplemental Cloud Product. ASOS detects clouds to 12,000 ft, and the ASOS 

supplemental cloud measurements provide cloud information, including heights more than 

12,000 ft, for a 50 km x 50 km area centered on the ASOS station. 

To minimize inconsistencies from station to station because of augmented human-based 

observations (Perez 2001), the ISH ASOS GD fields were used instead of the GF1 total sky 

cover field (NCDC 2004) to assign sky cover amounts below 12,000 ft for low clouds. The 

GD fields are sky cover summation fields that denote the portion of the celestial dome 

covered by all layers of clouds below a given height. Typically, as many as three GD fields 

might be present. For this work, the GD field with the greatest cloud-based height not 

exceeding 12,000 ft (3,657 m) was used for the total sky cover below 12,000 ft. GD fields 

with cloud base heights that exceeded 12,000 ft were ignored because they were assumed to 

be from human-based observations. GD sky cover amounts are integer values from 0 to 4 

based on the few-scattered-broken reporting methodology. The representation in oktas, and 

the conversion to hundredths that was used to be consistent with sky cover amounts for 

heights above 12,000 ft, is shown in Table 14.

0 Clear 0 0 

1 Few 2 or less 25 

2 Scattered 3–4 44 

3 Broken 5–7 75 

4 Overcast 8 100 

For heights above 12,000 ft, the ASOS supplemental cloud data were used to determine sky 

cover amounts representing middle and high clouds. These data include three five-by-five 

matrices that provide cloud type (high, middle, or low), cloud top pressure, and effective 

cloud amount (percent or hundredths). If the cloud top pressure indicated that the cloud top 

was below 12,000 ft, the sky cover for the matrix element was assumed zero, and the ground 

measurement was used. Otherwise, cloud amounts were summed and then divided by 25 to 

give an average total sky cover amount. Opaque sky cover amounts were determined in a 

similar fashion after applying opacity factors to the individual cloud amounts based on cloud 

type (low clouds opacity factor = 1.00; middle clouds opacity factor = 0.93; and high clouds 

opacity factor = 0.44). See Figure 5.

amounts determined from the ASOS supplemental data are combined using a random overlap 

equation to account for the low clouds overlapping the high and middle clouds. 

Sky Cover (hundredths) = 100 – [(100 – low amount) x (100 – high and middle 

amount)]/100 

This procedure appears to work reasonably well to minimize inconsistencies from station to 

station because of augmented human-based observations. 

In subsequent NSRDB tasks, we discovered the ASOS Supplemental Cloud Product was not 

available for several hundred of the candidate NSRDB sites, including all sites in Alaska and 

most in Hawaii. This placed significant restrictions on the geographical coverage and number 

of sites in the new NSRDB. To address this situation, a statistical method of estimating cloud 

cover was developed by computing probability distributions of total cloud cover (oktas) 

relative to opaque cloud cover amounts for every site where both total and opaque 

measurements were available from either human observations or the supplemental cloud 

method. These site-specific monthly distributions derive from the relative number of 

occurrences of each of the nine total cloud amounts for each of the nine opaque cloud 

amounts (in oktas as an integer range from 0 to 8). An example of the resulting distributions 

for the first 2 months of the year is shown in Table 15. For a given value of opaque for each 

month, the resulting probabilities of each okta of total cloud cover are shown in the columns 

across the table. The total count of samples used to create the table is in the Count column.

For this method, the ASOS total cloud report was considered primarily as a measurement of opaque 

clouds because the ASOS cloud measurement is limited to 12,000 ft and most translucent clouds occur 

above that altitude. At those times when only ASOS data are available, a total cloud amount for a 

particular hour is derived by randomly selecting a total cloud cover value based on the probability 

distribution derived from the ensemble of reported ASOS values. For sites that have neither the ASOS 

Supplemental Cloud Product nor the manual cloud observations necessary to create the probability 

distributions, the process uses the distribution table from the geographically nearest site. Better 

pairings of sites for this purpose could be possible if based on climatology, but project resource 

restrictions prevented the evaluation of each site based on climate. 

For Caribbean sites, no nearby sites with cloud tables exist. Sites in Florida were chosen for the 

pairings according to Table 16 based on an examination of the geography surrounding the sites using 

aerial photography.

A similar process was developed to derive opaque clouds from total cloud data for sites where 

human cloud observations included total but not opaque cloud observations (a common 

situation at military sites). 

Although the effectiveness of this technique may be diminished by interannual variability of 

distributions, the difference between total and opaque clouds is typically less than one okta. 

Thus, the derivation of total cloud values and possible errors are secondary to the dominant 

ASOS measurement. 

2.1.3 Aerosol, Water Vapor, and Ozone Estimates 

Both the METSTAT and SUNY models require input aerosols, water vapor, and ozone. The 

1961–1990 NSRDB used only DNI measurements to estimate broadband aerosol optical 

depth (BAOD). Today, much less measured DNI data are available, but much more aerosol 

data are available from other sources, including sun photometers and satellite-based estimates. 

The compilation of these data sets is described in sections 2.2.1.2, 2.2.1.3, and 2.2.1.4. 

2.1.4 Solar Measurements and the Evaluation Data Set 

Solar model validation relies on high-quality solar radiation measurements to evaluate model 

performance. A significant part of the update effort was to find, acquire, and quality-assess 

surface solar measurements to form an evaluation data set. These data sets would also be used 

in the measured solar data fields of the completed NSRDB. Thirty-three measurement sites 

were considered for the evaluation project based on their instrumentation, period of record, 

and proximity to NWS sites (see Table 17). Most data were available from data distribution 

Web sites maintained by network operators. Data were downloaded to NREL computers, 

imported to a database, and then evaluated with several quality-assessment tools, including 

SERI-QC (NREL 1993).

A data analyst used a rough scoring technique to evaluate data quality for each station-month, 

where 0 = missing or unacceptable, 1 = conditionally acceptable, and 2 = acceptable. A 

monthly mean score across all stations was calculated, and Figure 6 shows the moving 12-

month average of these monthly means for the period of available data (1996–2003). A peak 

in data quality/availability is evident between 1999 and 2000—the 2 years ultimately chosen 

for the test-case evaluation data set.

Note: The plot in Figure 6 should not be misinterpreted as indicating the absolute quality of 

solar measurements in the United States. The scale is arbitrary and mixes missing data with 

data quality—two distinct and not comparably scaled characteristics of data. Further, not all 

data from all stations were available at the time of the evaluation. The plot is presented only 

as an indicator of the best years to consider for the NSRDB model evaluation. 

2.1.5 Selection of the NSRDB Model 

Three models were evaluated for modeling NSRDB data: the NREL METSTAT model; a 

model developed by the Northeast Regional Climate Center for the American Society of 

Heating, Refrigerating and Air-Conditioning Engineers (Belcher 2004); and the SUNYdeveloped satellite model (Perez 2002). 

Several modifications have been made to the METSTAT model since its use for the 

original NSRDB. 

• The multiple-reflectance algorithm was modified for better performance under 

overcast skies by using ceiling height as an input rather than present weather (Vignola 

1997, Myers 2002). 

• A software switch that adjusts for the human perception of cloud amounts nearer the 

horizon being greater than actual was added for the perspective function. This function 

was turned off when the model was running on ASOS-based data, which is determined 

by examining only clouds directly overhead. 

• When running the model with the statistics “on,” cloud cover amounts were not 

randomized if the total sky cover was 0 or opaque sky cover was ten-tenths. (If opaque 

sky cover is ten-tenths, the opaque sky cover should not be randomized to a value less 

than 10, which results in direct normal values greater than zero for overcast skies. 

Similarly, if the total sky cover is zero-tenths, it should not be randomized to a greater 

value). Also eliminated was the procedure that modifies the random number for 

consecutive clear or cloudy hours. 

 38
• Cloud indexing changed to allow for fractional cloud amounts. 

The analysis of the test data sets and the evaluation of the results are treated more thoroughly 

elsewhere (Myers 2005). The analysis data set included those hours from all sites for which 

measured and modeled output data for all models were concurrent. This process eliminated 

two sites from the analysis because there were no overlapping data (Barrow, Alaska, and 

Hermiston, Oregon). The analysis compares the measured data to the output for each model 

using the statistical measures of root mean square error (RMSE), MBE, frequency 

distributions, probability distributions, correlation, and autocorrelation. 

 39
The analysis reveals few significant differences among the three candidate models (i.e., 

Northeast Regional Climate Center, SUNY, and METSTAT). The GHI monthly mean daily 

total (MMDT) MBE for all models ranged from -0.06% to 1.73%, and the RMSE ranged from 

5% to 8%. The uncertainty of the validation data is estimated to be about 5%–10%, which 

easily encompasses these errors. The DNI MMDT RMSE was somewhat larger, but all 

models were very close and ranged from 13.7% to 15%. Figure 7, which shows errors for 

hourly global irradiance, illustrates not only the closeness of the model performance but also 

the similarity of excursions for all models in site-to-site variability. These excursions may 

indicate a common bias in the models or input data or an error in the ground validation data. 

Whatever the cause, it is important in this context to note that all models perform similarly. 

Figure 8 shows measured versus modeled DNI MMDT.

regression fit, and correlation coefficients by model 

The study concluded that each model performed comparably in comparisons with measured 

ground data, and the decision for which model to use rested less with technical considerations 

and more with those of convenience. In that context, the METSTAT model, which is already 

deployed at NREL and with which NREL has considerable experience, was chosen. Also, 

because of its use with the original NSRDB, METSTAT may provide greater consistency 

with the older data set. 

2.1.6 Satellite Data Set 

The high-resolution gridded data set derived from the SUNY model provides a consistency in 

modeled output data for its period of record that is not available from the METSTAT model 

during the same period because of the cloud observation issues discussed in Section 2.1.2 and 

elsewhere. The SUNY model covers only the years 1998–2005, the period for which 

necessary GOES imagery was archived by the project. Acquiring older imagery is beyond the 

financial resources of the project, and other input data sets (such as snow cover) required by 

the SUNY model do not exist for the period prior to 1998. 

The output from the SUNY model is not suited for direct inclusion in the conventional 

NSRDB ground-based data scheme, yet it is desirable that it be included at those times when 

METSTAT model input data are not available or are of lesser quality. The satellite data are 

pixel-oriented and based in a different hourly time realm. The pixels in the gridded data carry 

latitude-longitude location information, so it is a simple matter of selecting a corresponding 

pixel using the coordinates of a ground station. (Although more sophisticated methods of 

selecting pixel values, such as pixel interpolation, could have been used, it was believed that 

 41
the 10-km resolution of the pixels was high enough that uncertainty in the final product could 

not be significantly improved for most locations.) 

The issue of converting the gridded data to the NSRDB time realm was more difficult. The 

SUNY satellite model produces solar estimates based primarily on input from GOES images. 

These images originate from two satellites: GOES-East and GOES-West, with the dividing 

line between 105o and 110o west longitude. The GOES-East images occur at 15 minutes after 

the hour, and the GOES West images occur at the top of the hour (referred hereafter as “:15” 

or “:00” images, respectively). These images and resulting solar estimates effectively 

represent conditions at the moment of image acquisition. However, the convention for 

NSRDB solar fields is an integrated hourly value represented by an hour-ending timestamp. 

Although the satellite model output is based on instantaneous conditions in a pixel, the 

resulting irradiance value represents some temporal and spatial integration of all clouds 

present in the 10-km satellite cell at the time of data acquisition. 

Though not strictly true, in this regard, the satellite output is considered an integrated value 

centered on the timestamp. By simple convention, this same value is equivalent to an hourending integrated value by simply moving the timestamp to the end of the integration period. 

For example, a 12:00 hour-centered value is the same as a 12:30 hour-ending value, or a 

12:15 hour-centered value is the same as a 12:45 hour-ending value. (To some degree, the 

METSTAT model, which relies on hour-ending sky cover observations, may also suffer from 

some temporal displacement of the estimated solar value. However, this effect is likely 

mitigated because the model deliberately modifies cloud amounts as part of its statistical 

algorithm and because the model was developed using hour-ending cloud observations 

coupled with hourly integrated solar measurements. Further, ASOS cloud observations 

emanate from 30-minute vertical cloud scans, which increases the temporal scope of the 

reported sky cover value.) 

The main challenge focuses on the shift in time from the hour-centered :00 or :15 value to the 

NSRDB convention that always ends exactly on the hour. After achieving the necessary 

temporal shift, the shift in time-stamp convention is trivial. However, accomplishing the 

temporal shift requires realistic estimates of interim-hour values that take into account not 

only the measured values but also known geometric and atmospheric characteristics of solar 

radiation. Simple interpolation does not suffice, as it fails to mimic true measurements and 

reduces the true variability in measured data. 

To develop a time-shifting method, a sample data set was produced from NREL’s Solar 

Radiation Research Laboratory irradiance measurements for 2005. This method uses a 

modified K-prime equation (Perez 1990) for each hourly model value to provide a 

representative normalization of the irradiance. 

 Kd′ = 1.031 • exp ( -1.4 / ( 0.9 + 9.4 / air mass ) ) – 0.35 

This normalized value can then be used to reconstruct an irradiance at the desired time. To 

illustrate the overall effect of shifting on daily totals, Figure 9 shows the error in daily totals 

(relative to unshifted daily totals) for the Solar Radiation Research Laboratory data set.

Figure 9. Error in daily totals (unshifted minus shifted) 

The conditions that cause these errors occur primarily because of diurnal cloud patterns, day 

length, and the temporal magnitude of the shift. 

• Day length affects the error because of shifting partial sunrise or sunset hours for 

which data may be either discarded or fabricated. 

• Cloud patterns affect error because they can cause asymmetric profiles. Errors in the 

morning will be opposite those in the afternoon, and these errors cancel nicely in a 

symmetrical day. However, if the morning and afternoon profiles are not balanced, an 

error in the daily total occurs. (These errors are also presumed present in the unshifted 

satellite data because instantaneously sampling at different times can result in different 

daily totals, whereas changing the time slices of integrated data will not alter the daily 

totals.) 

• The error because of the magnitude of the shift occurs as an imperfect model increases 

the distance from its anchor with the measured data point. 

Although the errors in daily totals in Figure 9 can be significant (ranging to more than 600 

Wh/m2), they tend to cancel throughout the year. In the Solar Radiation Research Laboratory 

data, the resulting annual errors for global and direct are about 1.2% and 2.0%, respectively. 

However, this may be an extreme case. Figure 10 shows the aggregate errors for the NSRDB 

sites using 3 years of satellite data (as a percent of unshifted aggregate totals).

Figure 10. Aggregate errors for satellite shifted data 

This plot shows error as a function of site longitude. An increase in the typical spread of 

errors rises from about ±0.25% for eastern sites to about ±1% for sites west of approximately 

100o west. Because of GOES-East and -West image acquisition times, the time shift to the 

hour-ending NSRDB convention for the eastern sites is 15 minutes and for the western sites, 

30 minutes. 

The SUNY model produces only values for global and direct solar radiation. When data are 

shifted, diffuse irradiance is calculated from the global and direct irradiances. Very few of the 

unshifted satellite data values were found to be unrealistic, such that the direct value exceeded 

the global value (direct converted to its vertical component using the cosine of the solar zenith 

angle). Before and after shifting, these conditions resulted in negative calculated diffuse 

values. The cause is probably traceable to the post-processing of data to smooth out 

singularities in the data grid. These data records—as well as others that might result in 

abnormally low, though positive, diffuse values—were adjusted to conform to a minimum 

clear sky diffuse envelope, DIFmin, based on aerosols and water vapor according to this 

formula (Ineichen 2004): 

DIFmin = GHI • (0.1 • (1 - 2•exp(-(11.2 • AOD + 0.333 • ln(W) + 2.106)))) • (1/(0.1 + 

0.9 • 0.98/(exp(-ALT/8000)))) 

where 

– GHI is the modeled global horizontal irradiance (Wh/m2) 

– AOD is the BAOD 

– W is the precipitable water vapor (cm) 

– ALT is the station altitude (m). 

 44
In cases in which the calculated diffuse irradiance is less than 85% of DIFmin, the calculated 

diffuse value is set to DIFmin, and the direct beam value, DNI, is replaced with: 

DNI = (GHI - DIFmin) / cos(ZEN) 

where ZEN is the solar zenith angle. 

These modified model data are flagged according to Table 7 but are not flagged in the SUNY 

gridded data set. 

2.2 Sources of Solar Radiation and Meteorological Data 

This section describes the sources of solar radiation and meteorological data that were used to 

produce the updated NSRDB. 

2.2.1 Data Acquisition 

NCDC provided all of the surface meteorological data for the entire period of record. Solar 

radiation data were collected from several sources. These are: 

• ARM Program Network, run by the Department of Energy 

• FSEC, run by the State of Florida 

• Historically Black Colleges and Universities Network, run by NREL 

• ISIS Network, run by the National Oceanic and Atmospheric Administration 

• SURFRAD Network, run by the National Oceanic and Atmospheric Administration 

• University of Oregon Solar Monitoring Lab network 

• University of Texas Solar Energy Laboratory. 

See Section 2.3.6 for details of how measured solar radiation data were processed for the 

NSRDB update. 

2.2.1.1 Meteorological Data 

The meteorological data were available from the NCDC ISH data set (Lott 2001), which 

contained all model input data except for precipitable water, aerosols, ground albedo, and 

ozone. The sources used for these special inputs are detailed below. 

2.2.1.2 Aerosols 

Cloud cover is the dominant input for solar models (excluding solar geometry). Next are 

aerosols, which under clear skies are the dominant meteorological input, which makes them a 

critical factor for estimating the resource for solar power applications. The 1961–1990 

NSRDB used only DNI measurements to estimate BAOD, values that were subsequently 

hand-contoured for the United States and fitted to a seasonal cosine function. Today, much 

less measured DNI data are available, but aerosol data from other sources, including sun 

photometers and satellite-based estimates, are more abundant. These sources produce spectral 

rather than broadband data, so massaging of the data became necessary to make them usable 

by the METSTAT and SUNY models, both of which use BAOD as inputs. 

 45
A combination of surface sun photometry, satellite data from the NASA Multi-Angle Imaging 

SpectroRadiometer (MISR) and Moderate Resolution Imaging Spectroradiometer (MODIS) 

satellite-based instruments, and legacy DNI estimates of BAOD allowed creation of monthly 

mean estimates of BAOD for all locations in the United States. Spectral AOD data were 

converted into BAOD using estimated Ångström Alpha parameters from sun photometry 

(Gueymard and George 2005). Using monthly mean BAOD values rather than specific daily 

or hourly values is likely to introduce significant errors in direct and diffuse hourly irradiance 

predictions under clear skies. Limitations in existing data and budget constraints prevented the 

derivation of more detailed datasets. Still, it is emphasized that the approach used here is 

conducive to overall better accuracy than what was done for the 1961–1990 NSRDB. 

All BAOD data were merged, interpolated, and adjusted to local elevation through use of an 

exponential function (Figure 11) and regridded if necessary. These monthly values were 

finally smoothly fit to daily values using a mean-preserving interpolation method (Rymes 

2001). Values in the period of July 11, 1991, through Dec. 31, 1994, were adjusted with an 

additive factor, AODstrat, to represent the effect of additional stratospheric aerosols from the 

Mount Pinatubo eruption using a double function of date with site-specific latitude 

parameters. The first is a ramp-up function, starting with July 11, 1991.

2.2.1.3 Ozone 

Total column ozone is derived from daily satellite observations from the Total Ozone Mapping 

Scanner (TOMS). Scans occur once per day on a grid with spatial resolution of 1 ̊ in latitude 

and 1.25 ̊ in longitude. The missing data are replaced with long-term mean values for that 

location. Ozone has only a second-order effect on broadband irradiance; hence, the uncertainty 

in the TOMS measurements or their replacement is not of concern. 

2.2.1.4 Precipitable Water 

NREL used the NVAP data set for daily estimates of water vapor on a 1o x 1o grid. NVAP 

integrates sounding data with satellite measurements of atmospheric water vapor. For the 

years 1988–1999, NVAP provides once-daily estimates of water vapor on a 1o x 1o worldwide 

grid. For years 2000 and 2001, NVAP provides the data on a 0.5o x 0.5o grid twice daily. 

These data were interpolated in space to the location of each of the NSRDB stations and 

interpolated in time to provide hourly data for all stations for the years 1991–2001. 

 47
Because of the limited period of record for the NVAP data set, the years 2002–2005 required 

a new source of data. For this, the recently released NARR was chosen. This data source 

provides column water vapor every 3 hours on a nominal 32-km grid. This data product uses a 

data assimilation model derived from National Center for Environmental Prediction weather 

prediction models to interpolate weather observations onto a numerical grid. The data 

observations for precipitable water include radiosondes, dropsondes from airplanes, and the 

infrared radiance data from the Television Infrared Observation Satellite Operational Vertical 

Sounder-1B satellite (over water). 

Geographic information system analysis techniques were used to match each of the NSRDB 

stations with its nearest NARR grid point. Then, data from the NARR grids for each 3-hour 

period were downloaded and interpolated to hourly data files for each station. 

2.2.2 Derived Input Meteorological Data (Data Filling) 

When the 1961–1990 NSRDB was designed, serially complete solar data was a primary goal 

of the project. Rather than attempting to fill gaps in the measured or modeled solar radiation 

data, the solar model input parameters were filled and the solar irradiance was modeled based 

on the filled input parameters. Filling input metrological data for the model is preferred over 

filling output solar data because of the statistical nature of METSTAT, which imposes 

pseudo-natural variability on the output data (while still conforming to long-term means). 

Other meteorological parameters were also filled at the same time in an effort to produce a 

more complete output data set that is suitable for other applications. 

Important note: The data-filling methods described here were not designed to maintain climatological 

characteristics but rather to accomplish the goal of serial completeness with representative and 

realistic solar data. Thus, NSRDB filled meteorological data are not suitable for climatological work 

and should be used only as support data for solar technology applications. 

A criticism of the 1961–1990 NSRDB was that missing nighttime data were not filled 

(nighttime input data were not necessary for solar model operation). This approach had the 

benefit of increasing the population of sites in the NSRDB because many NWS sites routinely 

closed down at night—an operational constraint that would have eliminated them from a 

serially complete database. However, applications that required serially complete 

meteorological data were hampered by this approach. 

In the context of the above discussion, significant value would be derived from an updated 

NSRDB with both serially complete solar and meteorological data. However, stricter 

requirements for serially complete data will increase the probability of a site's exclusion from 

the data set. (Even at full-time sites, there can be gaps of days, weeks, or months.) To 

determine if the design goal of serial completeness was reasonable, other data-filling methods 

were investigated. 

The following methods were used in the 1961–1990 NSRDB: 

 48
• Short-term filling – For gaps of 5 hours or less, linear interpolation 

• Medium-term filling – For gaps of 6–23 hours, substitution of data from the same 

hours of adjacent days 

• Long-term filling – For gaps of 1 day to 1 year, substitution of data from the same 

calendar days from another similar year. 

Additional techniques were employed to fill missing data when NREL developed the Typical 

Meteorological Year 2 data sets (for those data gaps that still existed after NSRDB methods 

were applied). 

• Cloud cover was linearly interpolated over a nighttime-only gap. 

• Dry-bulb temperature was linearly interpolated over a nighttime-only gap and 

modified for expected non-linearities, such as more rapid changes near sunrise or 

sunset. 

• Dew-point temperature (which was not filled by NSRDB methods) was filled using 

psychrometric relationships with dry-bulb and relative humidity values (which were 

filled). 

• Missing nighttime relative humidity was filled using psychrometric relationships with 

dry-bulb and dew-point temperatures. 

• Wind speed and direction (up to 47 hours) were filled with linear interpolation and 

(wind speed) adjusted for expected diurnal non-linearities. 

• Precipitable water (up to 47 hours) was filled with linear interpolation. 

Another technique used for other projects is the Linacre method, which characterizes 

measurements from a nearby station to form a constant relationship with like measurements 

from the target site (Linacre 1992). Data at the target site are then filled with data from the 

nearby station and adjusted according to the relationship. This method was investigated but 

not used for the updated NSRDB because of various constraints. Rather, the method described 

below was used. 

Most meteorological data were extracted from the ISH data set. The following parameters 

were filled in the NSRDB production database: 

• Total and opaque cloud cover 

• Dry-bulb and dew-point temperatures 

• Relative humidity 

• Ceiling height 

• Barometric pressure 

• Wind speed and direction 

• Aerosol optical depth 

• Precipitable water 

• Ozone. 

 49
Relative humidity was not present in the ISH data set and was calculated using psychrometric 

relations of dry-bulb and dew-point temperatures after the completion of all data filling. 

A primary goal of the complete hourly data for the period of record is to form the basis for 

climatological normals and means. Although short gaps of 4 or 5 hours can easily be filled 

with interpolation, over a multi-year period, there may be operational circumstances that 

create larger gaps, sometimes of several months. Even one gap violates the goal of serial 

completeness; therefore, by developing methods to fill both large and small gaps, the number 

of sites included in the updated NSRDB (balanced against the downside of increased 

uncertainty attributable to the filling processes) was greatly increased. 

Data-filling methods were categorized in four levels: 

1. Short-term interpolation

Data gaps of up to 5 hours were filled with linear interpolation or, in the case of 

temperatures, a site- and month-specific diurnal profile imposed on a linear 

interpolation. Gaps that extended through the night were also filled with this method. 

2. Medium-term filling

Gaps of up to 24 hours were filled by building an average profile from the same hours 

of previous and subsequent days and attaching that profile to the end points of the gap. 

3. Long-term filling

Gaps of up to 1 year were filled by characterizing the data before and after the gap and 

then seeking the most similar data from other years to fill the gap. The first and last 12 

hours of the fill data were scaled to fit the end points of the gap, and the rest of the fill 

data were used without modification. When filling dependent parameters (e.g., drybulb and dew-point temperature and total and opaque cloud and ceiling height), fill 

data were pulled from the same source dates when possible. If this could not be 

accomplished, coupling limits were enforced between the parameters. 

4. Last-ditch filling

In a few cases, the above methods left gaps because of insufficient data before and 

after the gap for developing a diurnal profile or characterization. In these cases, data 

from the same days were examined from other years in random order to find an 

uninterrupted run of source data to fill the gap. In addition, if barometric pressure 

could not otherwise be filled, it was modeled from site elevation (resulting in a static 

value). If ceiling height could not be filled, it was modeled from a simple regression 

with opaque cloud cover. 

The data-filling process creates log files for methods 3 and 4 to document the source year of 

the fill data. The type and density of data filling are used to determine the uncertainty of the 

modeled data. 

 50
These methods created serially complete model input data for more than half of the NSRDB 

sites. The sites for which the process was not successful typically had several years of missing 

data. Many were new sites that began operations only in the latter years of the NSRDB update 

period of record. These sites, in particular, have the potential for an expanded and more 

significant period of record in the future as data collection continues. 

Because of the potential use of even incomplete data sets for some applications, the station 

classification system described in Section 2.3.7 was developed. 

2.3 The Production Process 

In the development of the software for the NSRDB update, most resources were dedicated to 

data preparation—collecting, organizing, filling, and storing data such that the solar modeling 

could be completed in a simple input-process-output production run. After completion of the 

production database, additional work was required to produce summary statistics products, 

format the data for distribution, and create NSRDB documentation. 

Data (both measured and modeled) were stored in a flat-file production database that holds 

one station-year per file and 106 fields, including measurement values and associated flags, 

per record. For speed of processing, the fixed-length data records were stored in the file as a 

binary image of the program’s data structure, and all production software included a library of 

database access routines for reading and writing the production files. An NSRDB extractor 

tool was developed to convert the binary data to ASCII comma-separated value format to 

facilitate viewing or ancillary processing of the data by the production and reviewing teams. 

During processes, backup copies of the database files were kept at each stage to guard against 

data loss or corruption and support easy modifications to processes. As software was 

developed, tested, and modified, this scheme allowed the production team to easily revert to a 

previous step and commence processing with modified software without having to reconstruct 

the entire database from the first step. 

The production database was initially created by filling only fields for the date and time, the 

calculated extraterrestrial solar radiation, and the solar geometry (solar zenith and azimuth 

angles). The remaining data fields were flagged as missing. Each significant step in the 

process to complete the database is detailed below. 

2.3.1 Meteorological Data Ingest 

For the 1961–1990 NSRDB, all hourly meteorological data were supplied to the project in the 

NCDC TD-3280 format (NCDC 1991), which consisted of simple hourly records with a topof-hour timestamp. This was imminently compatible with the hourly records of the NSRDB. 

The newer NCDC ISH format (NCDC 2004) has the ability to hold data with minuteresolution timestamps. Many observations with an on-the-hour timestamp in TD-3280 are 

actually taken at other times of the hour, and these data are represented in ISH at the actual 

time of observation. Further, some observations are recorded multiple times during an hour in 

the ISH data set. This required sorting and time-shifting of the meteorological data to conform 

to the NSRDB top-of-hour realm. 

 51
During reading of records from the ISH data file, each field of interest was identified, its 

timestamp recorded, and a validity score assigned based on its proximity to the top of the hour. 

Values with a timestamp more than 15 minutes before or after the top of the hour were 

discarded as non-representative of the NSRDB timestamp. From these candidate values for 

each parameter, the one closest to the top of the hour was chosen to be included in the NSRDB 

as that hour’s value. Fields for which no value was found were marked as missing. All ISH 

flags were transferred to the NSRDB flag fields. (When fields were missing and subsequently 

filled, the ISH flag for missing data was replaced with an NSRDB filled-data flag.) 

Special consideration was given to these fields: 

• Station pressure

If station barometric pressure was missing, the field was calculated from sea level 

pressure, dry-bulb temperature, and ISH altimeter setting if those fields were present. 

• Wind direction

With a wind speed of 0, ISH uses a missing value flag for the wind direction field (as 

the vector value is undefined at magnitude 0). To avoid the appearance of missing data 

in the NSRDB, a convention was adopted that placed 0 in the NSRDB field when 

wind speed is 0. To avoid ambiguity with measured vector values, winds from the 

north are given a direction value of 360o in the NSRDB. 

2.3.2 Cloud Derivations 

The supplemental cloud data from NCDC was processed with the ISH data and converted to 

values of percent cloud cover for total and opaque cloud cover (see Section 2.1.2). These results 

were placed in the NSRDB production database. These percent values were converted to the 

nearest tenths for running the METSTAT model and inclusion in the NSRDB distribution files. 

A process was run to create the cloud distribution probability tables, which were kept in files 

external to the NSRDB database for use in the subsequent process to fill total or opaque cloud 

fields when one of the two observations was missing (see Section 2.1.2). 

2.3.3 Aerosols, Water Vapor, and Ozone 

• Aerosols

Using the methods described in Section 2.2.1.2, monthly mean aerosol values for each 

pixel in the SUNY grid were produced. For each ground station in the NSRDB, the 12 

monthly mean values were extracted from the corresponding cell and then duplicated 

for each of the 15 years in the 1991–2005 NSRDB update period of record. The 15-year 

time series of monthly mean values were then interpolated using a mean-preserving 

smoothing algorithm (Rymes 2001) that produced daily values. These values were then 

adjusted for the effects of the Mount Pinatubo eruption for years 1991–1994. The final 

daily values were then duplicated for the 24 hours in each day. The smoothed daily 

values were subsequently randomly perturbed by the METSTAT model. 

 52
• Water vapor

A time series of hourly water vapor values was produced for the period of record 

according to the methods described in Section 2.2.1.4 and then added to the 

production database. 

• Ozone

A time series of daily ozone values was produced using the methods described in 

Section 2.2.1.3 and then added to the production database. 

2.3.4 Data Filling 

A single program performed the data-filling methods described in Section 2.2.2. The fields 

filled are listed in Table 18. For Method 1 (short-term interpolation), the table lists the 

maximum number of hours for interpolated data. 

 Table 18. Filled Parameters and Short-Term Filling Limits 

Parameter Maximum Interpolation (Hours) 

Total and opaque cloud cover 5 

Dry-bulb and dew-point temperatures 5 

Relative humidity 5 

Ceiling height 5 

Barometric pressure 47 

Wind speed and direction 5 

Aerosol optical depth 5 

Precipitable water 5 

Ozone 23 

For the long-term filling process, which filled gaps using a continuous data series from the 

same dates in other years, a dividing line was determined between automated and manual 

cloud observations at each site. Mixing of these types of cloud data was prevented during 

filling. Further, when dependent parameters were subjected to long-term filling, the selection 

algorithm attempted to pull fill data for the related fields from the same records. 

Dependent parameters are those for which a change in one can cause a direct change in 

another. These are: 

• Total and opaque clouds and ceiling height 

• Dry-bulb and dew-point temperatures 

• Wind speed and wind direction. 

In all filling methods for clouds, ceiling height, and temperatures, physical relationships were 

artificially enforced such that values for opaque cloud cover remain less than or equal to total 

cloud cover, ceiling height is unlimited with 0 cloud cover, and dew-point temperature 

remains less than or equal to dry-bulb temperature. 

 53
2.3.5 Solar Modeling 

The SUNY satellite model was run by SUNY staff using gridded aerosol, water vapor, and 

ozone inputs provided by NREL from the data sources and techniques described 

previously. The gridded solar output files were transferred to NREL, where the solar values 

were time-shifted, the diffuse irradiance calculated, and data formatted for distribution. The 

pixel-based time series for each ground site was extracted and inserted in the production 

database. The SUNY process provided serially complete data for 1998–2005, so no 

additional filling was necessary. 

NREL ran the METSTAT model for each site using model input data drawn from each record 

in the production database and wrote the resulting solar values back to the database. The 

process also saved to the database the aerosol values randomized by the model. When the 

process encountered missing input parameters, the METSTAT solar fields were not filled. 

2.3.6 Adding Measured Solar Data 

Few solar measurement sites are colocated with meteorological sites. Because of the need for 

meteorological data to model a complete period of record and the sensitivity of solar 

geometry to geographic location, all NSRDB sites with measured solar radiation take on the 

coordinates of the measurement site rather than the meteorological site. However, the site 

name and identifier remain that of the meteorological site (with a bracketed annotation in the 

name that refers to the measurement site and network). This is necessary to accommodate 

accurate solar geometry and existing identifiers for cataloging. 

All such pairings were within 45 km of each other, and most were much closer. This may lead 

to some confusion among users who map site coordinates and find a named major 

international airport located, for example, at a nearby university campus or farm. To mitigate 

this confusion, NSRDB station metadata list both the meteorological and solar coordinates 

(see Appendix A), but all solar data are based on the solar site coordinates. 

The measured solar data were obtained from the sources shown in Section 2.2.1. A variety of 

formats included measurements with time resolutions of 1, 3, 5, 15, and 60 minutes. 

Instrumentation included various makes and models of thermopile instruments, silicon-sensor 

instruments, and rotating shadowband instruments (also silicon-based). 

Several processes were necessary prior to including the solar data in the NSRDB 

production database. 

• The rotating shadowband radiometer data were corrected for spectral biases. 

• The data were imported into the Data Quality Management System (DQMS) 

(Augustyn + Company 2004) for analysis. 

• The data were quality-assessed using SERI-QC software (NREL 1993). 

• The data were integrated to hourly values (for sub-hourly sampled data sets). 

• The hourly data were quality-assessed using SERI-QC. 

• The data were exported from DQMS to the NSRDB database. 

 54
Each step is described below. 

2.3.6.1 Correcting the Rotating Shadowband Radiometer Data 

Several sites employ rotating shadowband radiometers as a low-cost method of collecting data. 

These instruments have known deficiencies related to a nonlinear spectral sensitivity of the 

sensor, a silicon-based device with a spectral response significantly different from the 

absorption characteristics of thermal-based solar technologies (Augustyn 2002). This is more 

apparent for clear-sky conditions and particularly for the diffuse measurement, under which the 

sensor sees a deep blue sky, a portion of the spectrum for which the device is less sensitive. 

Some newer models of the instrument have compensation built in to the data acquisition 

system, but no data used for the NSRDB had this feature. Using a correction method refined 

by the University of Oregon (Vignola 2006), all rotating shadowband data were processed and 

the files created with corrected data to minimize the spectral bias. The original uncorrected 

data were not used for the NSRDB. 

2.3.6.2 Importing to DQMS 

Each data set was imported to the DQMS software in its native time resolution to provide a 

common format-independent platform for all solar measurements. This required special 

reformatting software for each data source to put the data in a form easily ingested by DQMS. 

2.3.6.3 Quality-Assessing the Data 

DQMS includes the SERI-QC quality assessment program, and SERI-QC boundaries of 

expected values were determined for each site-month of data using the QC-FIT program (a 

SERI-QC utility). Each data set was then subjected to SERI-QC to determine its overall 

quality and filter data with egregious errors from the subsequent process to integrate the 

hourly values. Only measured fields were imported, as some data sets include calculated 

parameters based on two other components. This included all of the rotating shadowband 

data, as the direct value is a calculated field. The SERI-QC software produces a better 

analysis of data quality without the use of calculated fields. (The direct component was later 

calculated for the hourly NSRDB values.) 

2.3.6.4 Integrating and Quality-Assessing the Hourly Data Values 

The sub-hourly resolution data were exported from DQMS, integrated in a separate process, 

and then re-imported to DQMS as new hourly data sets. New SERI-QC boundaries were 

determined for each site-month of the hourly data and all data flagged in DQMS. 

2.3.6.5 Exporting Hourly Data for the NSRDB 

Hourly data files with SERI-QC flags were exported from DQMS and prepared for importing 

to the NSRDB. The process to add the data and flags to the NSRDB included functions to fill 

missing solar values of global, direct, or diffuse if the other two components were present. 

This included all of the rotating shadowband radiometer data, other sites that routinely 

recorded only two components, and occasional fields missing in three-component sites 

because of operational or data quality problems. All calculated data were specifically flagged 

in the NSRDB (see Section 1.4.5.1). 

 55
2.3.7 Statistical Summaries 

Software was created to produce the statistics and threshold files (see Section 1.4.4) according 

to specifications for the 1961–1990 NSRDB, with minor format changes to accommodate 

different years and a longer station identifier. This process also created tables of percent 

missing and data quality for each site. These were used for the plots in Appendix A. Based on 

an analysis of this data, the software also assigned site classifications. A Visual Basic 

program developed for Microsoft Excel and Word automated the creation of Appendix A. 

The site classification assignments are an important conformance to specifications that data 

quality be communicated to users. Classifications were based on the uncertainty of the data 

and its completeness. Because of plans to create value-added data sets, such as Typical 

Meteorological Year, Class I and II stations were required to have no missing data in the 

following fields: 

• Solar (global, direct, diffuse) 

• Temperature (dry-bulb, dew-point) 

• Humidity 

• Wind speed 

• Aerosol optical depth 

• Precipitable water 

• Station pressure. 

If any data were missing in these fields, the station was designated Class III. If a station had 

less than 3 years of significant data density, it was not included in the NSRDB. (About half of 

the approximately 3,000 ISH stations in the United States were excluded.) 

The algorithm distinguishes between Class I and II stations by examining the uncertainty for 

each hourly modeled value in the global field. If less than 25% of the data for the 15-year 

period of record exceeds an uncertainty of 11%, the station receives a Class I designation. 

Otherwise, it receives a Class II designation. Although the 11% threshold between high and 

low uncertainty may seem arbitrary, based on the uncertainty calculations in Section 1.4.5.1, 

this value easily discriminates between the data modeled with good human-observed or 

satellite-derived cloud cover and the filled or statistically derived cloud cover. It is important 

to note that because of the changes in NWS cloud observations, all sites had significant 

periods of high uncertainty data in the middle 1990s. But, in this sense, the user can more 

easily identify the best available data (not to imply or be confused with perfect data) and be 

alerted to data with higher uncertainty. The plots of high and low uncertainties in Appendix A 

allow users to further refine thresholds for station quality based on the requirements of 

specific applications. 

2.3.8 Distribution Data Extraction 

Extraction software was written to create the files to transfer the distribution fields to NCDC. 

The NCDC data set is a subset of the production database and contains those fields deemed 

most valuable to a broad range of users. 

A different version of the production database was created for distribution at NREL. This data 

set contains all fields except for the meteorological fields, but it adds more solar fields.

If the name of the measurement site is dissimilar from the meteorological site, that name 

appears in the brackets also. In this example, the solar site is similar to the measurement 

site name (Moab, UT), and only the network affiliation abbreviation appears in brackets 

(University of Oregon Solar Radiation Monitoring Laboratory).

Station ID 

The six-digit 

USAF site 

code 

Station information

Class designation – See Section 2.3.7 for an explanation of the class designation. 

If the site holds measured data (as this one does), the class designation is 

followed by a notation that measured data are included. 

Solar coordinates – These coordinates correspond to those used for the modeled 

or measured solar radiation data. 

Meteorological coordinates – These are the coordinates of the station that collects 

the meteorological data. If the station holds no measured solar data, these will 

match the solar coordinates. Because of the sensitivity of solar measurements to 

geographic location, coordinates for sites with measured solar data default to 

those of the solar measurement site. In such cases, the meteorological 

coordinates are included for purposes of documentation. 

Latitude and longitude – These are in decimal degrees. Negative indicates west of 

the prime meridian. Elevation is the site altitude above mean sea level (meters). 

Time zone is the hourly offset from Greenwich Mean Time (negative is west of 

GMT). 

Data quality plot

This plot shows three 

aspects of data quality 

on the same plot: 

• Proportion of low and 

high uncertainty data 

as green and yellow 

stacked bars, 

respectively (see 

discussion in 

Section 2.3.7) 

• Proportion of missing 

data as red bars 

• Percent of measured 

data present in the 

data set as the black 

line graph with circle 

markers.

Appendix B: Old and New NSRDB Station Equivalencies 

This section lists the original 239 1961–1990 NSRDB sites (in order by WBAN ID) with their 

equivalent sites in the 1991–2005 NSRDB update and USAF ID. All of the equivalent sites in 

the updated NSRDB are either Class I or Class II stations, with the exception of Flagstaff, 

Arizona, and Boulder, Colorado, which are Class III. Although some sites have slightly 

different coordinates because of changes in station location or inclusion of different sites with 

measured solar data, all pairs of sites listed here should be climatically similar.
