Document:
This data set contains monthly mean precipitation sums from Russian arctic stations. Precipitation measurements were acquired using a Tretyakov precipitation gauge. Data have not been adjusted for wind bias. Data from 1967 and later are corrected for wetting loss (this correction was made by observers as they recorded the station data). Precipitation measurements from 216 stations are available. An analysis of existing precipitation data sets confirmed that data from these stations are not, at the time of publication, available in other commonly used precipitation data sets. Most data records begin in 1966 and end in 1990.

These data are provided as part of an ongoing effort to fill gaps in the precipitation record available to the arctic research community.
A tab-delimited ASCII text file, precip_station_list.txt, is available via FTP. This file lists the station name, latitude (deg N) and longitude (deg E) of the station position, the temporal range, the river basin name (if known) and the station number (if known). This station list was created by NSIDC based on a station list with station positions provided by V. Vuglinsky. Users should note that station name spellings and positions can vary depending on the original data source and on the interpretive translation between languages.
Precipitation is the only parameter in this data set. It is provided in monthly mean precipitation sums in mm.
Data were collected at stations between 50.17 N and 69.77 N, and 38.25 E and 164.17 E. Monthly data records in this data set begin in 1966 and end in 1990. The map in Figure 1 displays the location of meteorological stations where these precipitation measurements were taken.
The data files are in tab-delimited ASCII text format.
The following text shows the first segment of the northern_dvina_precip.txt file.
In this example, Northern Dvina is the river basin, Biryakovo refers to the station name, Year gives the year the precipitation measurement was taken (ranges from 1966 to 1990), values 1-12 denote months (1 = January and 12 = December), and the sum is the sum of the monthly mean precipitation measurements from a specific station (Biryakovo) for a particular year.
Precipitation is recorded in mm.
If the river basin name was unknown for a station at the time of the data set publication, the station data were put in the output_precip.txt file.
The data files range from 13 KB to 64 KB.
The precipitation data were transferred to NSIDC from the State Hydrological Institute in St. Petersburg, Russian Federation by V. Vuglinsky. The original precipitation data were written records, prepared by regional hydrometeorological authorities. Editors at the regional hydrometeorological authorities quality control data before publishing the data in monthly precipitation bulletins. Because the data were transcribed (keyed) at the State Hydrological Institute, the data are subject to transcription errors. NSIDC did not perform a quality assessment on the precipitation data.
Users should note that precipitation sums for certain months are missing from some stations. Reasons for the missing sums include that certain stations had closed, there were gaps in the observations, the quality of the data was poor or a data value was lost during transmission. A file containing the missing values is available. Note that not every precipitation file was exhaustively checked. Therefore, there may be missing precipitation values that are not listed in the missing values file.
Measuring arctic precipitation accurately is difficult. Users of these data should first become familiar with error sources inherent in all arctic precipitation measurements. We strongly suggest consulting Groisman and Rankova (2001) and Groisman et al. (1991) and references contained therein, and the documentation on gridded precipitation fields in Arctic Climatology Project (2000) for an introduction to precipitation measurement issues.
The original monthly precipitation sums were acquired from the official monthly precipitation bulletins prepared by regional hydrometeorological authorities in paper form and transcribed (keyed) to digital form at the State Hydrological Institute.
Meteorological observations including precipitation were performed according to the Manual for Hydrometeorological Stations and Posts, Gidrometeoizdat, 1985 (from "Nastavlenie gidrometeorologicheskim stantsyyam i postam." Vypusk 3, chast’ 1). A standard meteorological site was 26 m by 26 m, and was located on relief typical of the area. It was more than 100 m distant from any bodies of water, and at a distance 20 times the height of any obstruction (such as trees or a building). A meteorologist measured the amount of precipitation two or four times every 24 hours (see Groisman et al.,1991 for detailed instructions). Duration and type of precipitation were observed continuously. Amount of precipitation was measured to a precision of 0.1 mm.
The data were received at NSIDC in two deliveries, on 3 December 2004 and also on 30 January 2006. These data, in Excel spreadsheets, were combined with data from V. Vuglinsky already in use by NSIDC researchers to create this data set. The data were reformatted from Excel spreadsheets to tab-delimited ASCII file.

Planning for this data set began in 2003, as part of a Study of Environmental Arctic Change (SEARCH) project to acquire data sets that may be needed for an arctic reanalysis effort. Precipitation data was seen as important, but identifying what stations or temporal coverage was missing from the many precipitation data sets already available was a necessary first step. A table of precipitation data sets potentially valuable for arctic reanalysis was constructed, and a match was sought between the stations that could be acquired for this data set and stations in most of the data sets in the table, based on proximity of station location (to within 0.25 degrees, or 27.75 km). In March of 2004, it was determined that the stations provided in this data set were not available elsewhere, with the exceptions noted below. For completeness, the precipitation data set table is included here as a document file (Precipitation_Dataset_Inventory.pdf) for downloading. This data set, G02170, is an extension of the “R4” data set in the table. The "R4" data have an associated station number in the station list. Station numbers are not available for other stations in the data set.
The document, G02170_Overlap_Stations.doc, contains a list of stations that appear in this data set and also in other readily available data sets (though the date range may be different) is available.

Gridded monthly mean precipitation, climatological means for period 1950-1990. See http://nsidc.org/data/g01938.html. Fields (250 km equal area EASE-Grid) were created from station data using iterated Cressman interpolation and a first guess (Legates and Willmott, 1990) field. Precipitation over land uses the Former Soviet Union Monthly Precipitation Archive, 1891-1993 and Canadian Monthly Precipitation (see below). Monthly precipitation totals for the Arctic Ocean are Russian North Pole (NP) drifting station data corrected for biases by Daqing Yang. There are no plans to remake these 12 average precipitation fields with additional data, but they are mentioned here because they were prepared with bias-corrected data and are a convenient representation of climatology.
USSR Monthly Precipitation for 622 Stations 1891-1999 (NCDC DSI-3720). Available from the NOAA National Climatic Data Center.
NSIDC previously distributed the following two data sets. These data sets were withdrawn because they duplicated data in the above two data sets distributed by NCDC.
Adjusted Monthly Precipitation, Snowfall and Rainfall for Canada (1874-1990).
These data sets were prepared by P. Groisman, NOAA National Climatic Data Center. The original data were purchased by NCDC from the Canadian Atmospheric Environment Service in the early 1990s and then subjected to bias corrections. A total of 6692 stations are available, extending from the beginning of record to 1990. Adjusted Monthly Precipitation, Snowfall and Rainfall for Canada contains only the corrected data, while Canadian Monthly Precipitation (TD-9816) has original data as well.
Monthly precipitation totals from 622 stations. Work on this archive began at the State Hydrological Institute in St. Petersburg in 1977. The data are available along with a file containing the correction factors so that it is possible to reconstruct the uncorrected data.
NCDC's Climate Services Branch produces global summary of day data for 18 surface meteorological elements including precipitation. These are derived from the synoptic/hourly observations contained in TD9956 (USAF DATSAV3 Surface data). Historical data are generally available for 1973 to the present, with some stations having data back to before 1930. Data from 1994 on are available online. Synoptic data undergo extensive automated QC. These data are quality controlled further as the summary of day data are derived. Data are ongoing, and are normally available a few days after the end of the data week . A visualization tool (CLIMVIS) can be used to plot data from individual stations.
Global Historical Climate Network Daily that is available from the NOAA National Climatic Data Center.
The GHCN contains monthly average temperature and precipitation data. The GHCN incorporates data from NCAR ds570.0, and from many additional sources. A subset of all GHCN stations is updated monthly (primarily those for which data from the Global Telecommunications System or GTS, are available). For any given station, the GHCN may have more than one time series and each time series taken singly may not cover the entire history of that station.
Provides monthly, seasonal and annual rain, snow and total precipitation from the second generation Adjusted Precipitation for Canada (APC2) dataset for over 450 locations. Series extend back to 1895.
Data from National Climatic Data Center (NCDC) Monthly Climate Data of the World, plus other data sources including World Weather Records from the Smithsonian Institution, the U.S. Weather Bureau, and the Department of Commerce. Standard parameters are sea level pressure, station pressure, temperature, and precipitation. Data from more than 4700 stations were quality controlled at NCAR by looking for deviations of greater than four or five standard deviations from the long period monthly mean. These extreme values were then manually inspected and either accepted, or set to missing. Updated yearly.
