The NASA STI Program Office ... in Profile

Since its founding, NASA has been dedicated to

the advancement of aeronautics and space

science. The NASA Scientific and Technical

Information (STI) Program Office plays a key

part in helping NASA maintain this important

role.

The NASA STI Program Office is operated by

Langley Research Center, the lead center for

NASA's scientific and technical information. The

NASA STI Program Office provides access to

the NASA STI Database, the largest collection of

aeronautical and space science STI in the world.

The Program Office is also NASA's institutional

mechanism for disseminating the results of its

research and development activities. These

results are published by NASA in the NASA STI

Report Series, which includes the following

report types:

• TECHNICAL PUBLICATION. Reports of

completed research or a major significant

phase of research that present the results of

NASA programs and include extensive data or

theoretical analysis. Includes compilations of

significant scientific and technical data and

information deemed to be of continuing

reference value. NASA's counterpart of

peer-reviewed formal professional papers but

has less stringent limitations on manuscript

length and extent of graphic presentations.

• TECHNICAL MEMORANDUM. Scientific

and technical findings that are preliminary or

of specialized interest, e.g., quick release

reports, working papers, and bibliographies

that contain minimal annotation. Does not

contain extensive analysis.

• CONTRACTOR REPORT. Scientific and

technical findings by NASA-sponsored

contractors and grantees.

CONFERENCE PUBLICATION. Collected

papers from scientific and technical

conferences, symposia, seminars, or other

meetings sponsored or cosponsored by NASA.

SPECIAL PUBLICATION. Scientific, technical, or historical information from NASA

programs, projects, and mission, often concerned with subjects having substantial public

interest.

TECHNICAL TRANSLATION.

English-language translations of foreign scientific and technical material pertinent to NASA's

mission.

Specialized services that complement the STI

Program Office's diverse offerings include creating custom thesauri, building customized databases, organizing and publishing research results...

even providing videos.

1. Data Set Overview

1.1 Data Set Identification

BOREAS AES Campbell Scientific Surface Meteorological Data

1.2 Data Set Introduction

This data set contains 15-minute data from 14 automated meteorology stations across the BOREAS

region in Canada. Included in these data are parameters of day, time, mean sea level pressure, station

pressure, temperature, dew point, wind speed, resultant wind speed, resultant wind direction, peak

wind, precipitation, maximum temperature in the last hour, minimum temperature in the last hour,

pressure tendency, liquid precipitation in the last hour, relative humidity, precipitation from a weighing

gauge, and snow depth.

Page 1
1.3 Objective/Purpose

These monitoring sites were established by the Atmospheric and Environment Service (AES) of

Canada to provide hourly weather reports, input to the operational program of forecasts and warnings,

input to operational weather prediction models, and climate data. The frequency of observations was

increased to 15 minutes at the request of the BOReal Ecosystem-Atmosphere Study (BOREAS). Data

collection for BOREAS began in August 1993.

1.4 Summary of Parameters

Parameters include: day, time, mean sea level pressure, station pressure, temperature, dew point,

wind speed, resultant wind speed, resultant wind direction, peak wind, precipitation, maximum

temperature in the last hour, minimum temperature in the last hour, pressure tendency, liquid

precipitation in the last hour, relative humidity, precipitation from a weighing gauge, and snow depth.

1.5 Discussion

Generally these stations were installed before BOREAS began, and conform to Environment

Canada's criteria for accuracy and exposure. Only stations Southend, Saskatoon (SK), and Waskesiu

Lake, SK, have a Fisher and Porter weighing precipitation gauge. Only Waskesiu Lake, SK, measures

snow depth.

The TBRG was cleaned, calibrated and leveled. The anemometer was

replaced with a rebuilt unit. Station pressure was checked against

the calibration barometer, and over 8 readings the average difference

was 0.49 mb with a range of 0.29 to 0.60, but no change was made

to the pressure offset. The Fisher and Porter was cleaned, calibrated

and recharged with glycol/oil. All other normal autostation

comparisons were completed, and were OK.

The alter shield was removed from the Fisher and Porter, and

replaced with a Nipher shield. The sonic transducer was replaced

with a new retrofit for the snow depth sensor.

Precipitation amounts reported from the Fisher and Porter gauge had

become suspect over the past several weeks, and in conjunction

with George Davies, it was decided that the problem might be a

malfunctioning shaft encoder. A new shaft encoder was installed,

and appears to be operating normally, but time will tell. It should

be noted that a significant amount of snow had accumulated on the

shield of the Fisher and Porter gauge, which very likely had a

significant impact on air flow over the gauge. No such

accumulation was observed on the snow gauge Nipher shield.

During the period Sep 21 to 23, 1994, a 60 foot tilting tower from

Downsview was installed, replacing the 60 foot Hossick tower. The

TBRG was cleaned and calibrated. The anemometer speed head was

WBL Bachelors Island, MB

The weather station is located on an island at the south end of Lake Winnipegosis. The nearest

community is the village of Winnipegosis, which is 10 km straight south of the island. Instrument

exposure is excellent in all directions. The station is situated on a flat open area of the island. It is high

enough off the lake shore to prevent damage from ice in the spring, but is close enough that it will be

ideal for its primary purpose as an aid to marine forecasting for this lake. It is located on a narrow spit

of land that is about 35 m across. The site is 1.4 m in elevation from the lake. The surrounding terrain

is sand and gravel, with only a couple of 2-m dead tree skeletons approximately 6 m to the south.

Otherwise, the surrounding area is lake. The nearest mainland is 2.5 km to the west.

Page 10
WFO (FFN) Flin Flon, MB

The instrument area is located on the airport property, adjacent to the U2A tower and ceiling

projector, about 150 m northwest of the airport terminal building. Exposure is excellent in all

directions, with no obstructions present. The surrounding countryside is Precambrian Shield with

numerous lakes, rock outcrops, and heavily forested areas. The station is located on a 1-km2 peninsula

at the midpoint of Lake Athapapuskow, a 20-km-long, 2-km-wide body of water running

south-southwest to north-northeast. A rocky ridge, rising some 30 m, lies 1 km southwest to

northwest of the station. The BOREAS Airborne Fluxes and Meteorology (AFM)-07 automated

meteorological station is co-located with this autostation.

WGX Gillam, MB

The autostation instrument area, located northeast of the aircraft ramp and adjacent to the existing

U2A tower, has excellent exposure. The area is about 175 m northeast of the airport terminal building

and 250 m northeast of the manned instrument area. The immediate terrain is ungrassed natural

ground, recently cleared of brush, and will need an annual brush clearing to maintain this exposure.

Gillam Airport is located 1 km northeast of the town of Gillam on a flat open area beside Stephen's

Lake. This reservoir lies to the west-northwest of the instrument area and is responsible for low stratus

and fog in the spring and fall at this site. Because the runway and airport roads are gravel, there is a

great deal of dust.

WHH Hunters Point, MB

The weather station is located on a long point of land at the north end of Lake Winnipegosis. The

point extends 4 km northeastward into the lake and divides it into two bays: Overflow Bay to the

north, and Dawson Bay to the south. The nearest settlement is Dawson Bay, which is near Highway

10 at the beginning of the point. Because the site is at the end of the point, almost surrounded by

water, instrument exposure is excellent in all directions, except to the southwest, down the length of

the point. The point was heavily wooded almost to the tip, and a significant amount of clearing was

required in order to improve the exposure. The southwest quadrant has some very tall trees that will

affect the wind flow from this direction. The surrounding countryside is heavily wooded with some

open areas of marsh, and a fringe of tall grasses adjacent to the lake

WWC Collins Bay, SK

The instrument area is located at the northwest edge of the Eldor Mines Collins Bay staff"

accommodation complex. The automatic weather station is co-located with the manned observing

program, sharing the same instrument area. The exposure is open to the south, west, and north,

offering good air flow. To the east, there is some sheltering due to the 42- by 8- by 4-m office trailer.

The mine site and the 30- by 30-m instrument area are located on a large plateau that rises about 60 m

above the surrounding countryside. Trees extend around the perimeter of the complex. The wind

equipment is mounted atop a 13-m tower in order to clear local obstructions, and is located in the

instrument area. The RM Young anemometer is co-mounted with the U2A anemometer on the same

mast at 10 m. The Collins Bay mine site is situated 4 km west of Wollaston Lake, and approximately 6

km south of Collins Creek. The terrain is rough and rolling, covered with 5- to 10-m evergreens.

Numerous small lakes, muskeg, swamp, rock outcrops and rivers extend to the north and west.

WLE Lucky Lake, SK

The station is located approximately 3.5 km south-southwest of the town of Lucky Lake. From the

intersection of #45 and #42, travel 0.5 km west on #42, cross the railway tracks, and then 3 km south

on grid road #646. The station is established on relatively flat, open farmland. Lake Diefenbaker is

situated 18 km south and curves to also be 15 km east as it winds its way northwards. To the east and

south, the topography is more undulating with a significant number of sloughs (usually dry) dotting

the landscape. Tree growth is at a minimum here, with only some planned shelterbelts breaking the

otherwise void prairie landscape. The observing site provides excellent exposure to all sectors.

Page 11
WLJ Meadow Lake, SK

The station is located on the Meadow Lake Airport property, 5 km west of the town of Meadow

Lake, and approximately 7 km west of Meadow Lake. The topography to the east, north, and west of

the airport is fairly flat, while to the south it rises from 480 m at the airport to 730 m 30 km south of

the airport. This hilly area is well forested, while mixed farmland surrounds the airport for a radius of

15-25 km in the other directions. The instrument compound is located north of the terminal building,

with cultivated farmland next to the site on the east, north, and west sides, and a trimmed grass area to

the south. The exposure of the instruments is excellent, with no obstructions to airflow in any

direction. The surface is grassed, and the compound is identified by a post and chain fence. The

automatic weather station is co-located with the manned observing program.

WFF Melfort, SK

The Melfort autostation is located at the Melfort CDA Experimental Farm some 200 m southeast of

the existing CDA climate station. The topography is generally flat farmland, with some shelterbelts.

There appear to be no serious restrictive forces at play to hamper representative data collection.

WBU Nipawin, SK

The Nipawin automatic station is co-located with the manned program, in a fenced, protected yard,

to the east of the aircraft parking and maintenance area. The station sensors share a common instrument

area exposure, on a protected 39- by 39-m site, identified by a chain and post fence. The site is grassed

and has excellent exposure in all directions. Air flow is unrestricted from all quadrants, and in the

immediate vicinity the only source of heat might be the taxiway and apron, some 50 m to the south. To

the east and south the surrounding countryside is flat, open farmland, with only the occasional natural

bluff or planned shelterbelt. The Saskatchewan River Valley lies to the west, approximately 1.5 km

distant, and runs north-south. To the north is farmland, with the outskirts of the town of Nipawin

starting at a distance of 1.0 kin. There is no sheltering of the instruments from any direction.

WRJ Rosetown East, SK

The station is located at the Rosetown Municipal Airport, located 4.2 km northeast of the town of

Rosetown in Highway #7. The instruments are located on a level, grassed area with open exposure in

all directions. Some effect may be noticeable from the airport hangers located 50 m to the north. These

hangers range from 3.9 to 5.7 m in height. A 56-m-high grain elevator is located 445 m to the

northeast of the instrument area. Local pilots have reported wind effects extending for up to 0.5 km

downwind of this obstruction. The surrounding countryside is flat, open cropland.

WJH Southend, SK

The station is situated in the northeast portion of Central Saskatchewan. The site is 180 km

northeast of the town of La Ronge, and approximately 5 km west of the village of Southend. The

immediate surrounding area is generally evergreen forest with some small areas of mixed deciduous

growth. Topography is best described as a series of forest covered ridges and hills interspersed with

rivers and lakes. The site lies approximately 0.5 km to the south and west of the southern end of

Numabin Bay of Reindeer Lake. Under a northeast wind, one may expect the water body to exert

some minor influence on "normal" data. A tree covered ridge running east to west lies approximately

1.0 km to the south. Ten-meter-high evergreens begin about 20 m south of the site. Short brush and

bush predominate to the immediate east, slowly giving way to the evergreens father east.

WSR Spiritwood West, SK

The station is located 2.6 km west of the town of Spiritwood, SK. The instruments are located on

a level grassed area adjacent to Highway #3. Exposure is open in all directions, with the only

obstruction being a bluff of 8-m trees 120 m to the southwest. The surrounding countryside is open,

flat cropland with frequent bluffs of trees. Witchekon Lake lies 3 km to the north.

Page 12
WLV Waskesiu Lake, SK

The station is located on the grounds of the Parks Canada Maintenance compound. The

instruments are located on a 22- by 12-m conditioned plot, open to the west, south, and east. To the

north sheltering can be expected due to large fir trees 15 to 17 m high. The Parks building and paved

equipment yard are situated to the southeast about 50 m. Open areas to the west and south are slightly

lower in elevation. With the exception of the north quadrant, exposure is fair to good. General

topography is rolling forest country. Waskesiu Lake lies 1.4 km to the northwest.

WIW Watrous East, SK

The station is located approximately 4 km east of the town of Watrous, SK, at the Saskatchewan

Wheat Pool Product Development Farm. To locate the station, travel north 1.3 km from the junction of

Highways #2 and #365 to Grid road 668. Go east on 668 3.2 km to a small white church and the

Product Development Farm sign. Travel south 1.2 kin, drive through the farm yard, and the station is

approximately 200 m east of the office complex. The instruments are located on a level grassed area

with open exposure in all directions. A low area of ground that may hold water in the spring or during

wet periods is just to the west of the instruments. The surrounding countryside is flat, open cropland.

Little Manitou Lake lies in a valley approximately 4.5 km north.

10.2.5 Data Verification by Data Center

An automated quality assurance program was run on this data set to identify anomalies, including

sudden jumps or drops ("spikes") in the data. Some of these problems are identified in Section 11.2.

11. Notes

11.1 Limitations of the Data

See Section 10.2.2.

11.2 Known Problems with the Data

Snow measurements (Fisher & Porter weight gauge and snow depth) are known to be poor. Some

automated quality assessment was done to identify spikes and other anomalies in the data. These

anomalies are also present in the original data and are not due to BORIS processing. Following are a

few examples of some anomalies that were detected for the various columns of data. This is not meant

to be a comprehensive list.

STN PRESS:

In 1993, spikes of 7 or 8 kiloPascals in a 15-minute period were observed in the data. In 1994, some

larger spikes were seen, such as the following 13-kPa change:

PRESS TEND:

In this data set, some spikes of 6 kPa were observed, but in general most values were less than 1. In

the 1993 and 1994 data, there are some very high values over 97.8 kPa. Most of these problems were

with the WJH, WLE, and WWC sites. In 1995 and 1996. some very high spikes were found in the

data from the WRJ site.

AIR TEMP 1 5M:

In 1993, some spikes of 5 degrees are not uncommon. In addition, some physically impossible values

were found.
