1. Data Set Overview

1.1 Data Set Identification

BOREAS AES MARS II Surface Meteorological Data

1.2 Data Set Introduction

This data set contains 15 minute meteorological data from six Meteorological 
Automatic Reporting System II (MARSII) meteorology stations in the BOReal 
Ecosystem-Atmosphere Study (BOREAS) region in Canada.  Parameters include site, 
time, temperature, dewpoint, visibility, wind speed, wind gust, wind direction, 
two cloud groups, precipitation and station pressure.  BOREAS received data for 
the Intensive Field Campaigns (IFCs) of 1994.

1.3 Objective/Purpose

These monitoring sites were established by Environment Canada to provide hourly 
weather reports to  1) provide input to the operational program of forecasts and 
warnings, 2) provide input to operational weather prediction models, and 3) 
provide climate data. 

The frequency of observation was increased to 15 minutes at the request of 
BOREAS. Data collection for BOREAS occurred during IFCs 1, 2, and 3 in 1994.

1.4 Summary of Parameters

Parameters include site, time, temperature, dewpoint, visibility, wind speed, 
wind gust, wind direction, two cloud groups, precipitation, and station 
pressure.

1.5 Discussion

Generally, these stations were installed well before BOREAS began, and they 
conform to Environment Canada's criteria for accuracy and exposure.

6.1 Data Notes

Not applicable.

6.2 Field Notes

The following was obtained from the inspection books.  Obviously some visits 
have not been recorded.

Normal practice is to disable the TBRG for the winter and to disable the 
weighing gauge for the summer. 

WEQ Swan River, MB 

Inspection 21-Mar-1994  
All instruments were cleaned and calibrated. Pressure averaged +0.235 mb 
different from the inspection barometer for 10 readings. Clouds were too high 
and too few to verify operation of the ceilometer. Temperature averaged 0.0 C 
different from inspection psychrometer for 9 readings.  The dewpoint was +1.2 
deg C different. A newly calibrated tipping bucket bridge was installed and 
checked. Bearings in both the speed and direction wind detectors were replaced. 
Visit 18-May-1995 F&P taken out of service and TBRG installed for the summer.

WDC Uranium City, SK
 
Inspection 06-Dec-1993  
All instruments were cleaned and calibrated. Pressure averaged -0.42 mb 
different from the inspection barometer for 10 readings. The wind speed detector 
and the dewcel were changed as per their replacement schedule. The wind 
direction indicator was still in good condition.

WJD Grand Rapids, MB 

Inspection 20-Apr-1993 
All instruments were cleaned and calibrated. Pressure averaged -0.55 mb 
different from the inspection barometer. Air temperatures were within +/- 0.2 
C, and dewpoint temperatures were within +/- 0.7 degrees C.  

Inspection 22-Jul-1994  
All instruments were cleaned and calibrated. Pressure averaged +0.654 mb 
different from the inspection barometer.

Inspection 29-Mar-1995  
All instruments were cleaned and calibrated. Pressure averaged +0.71 mb 
different from the inspection barometer for six comparisons. 
The dewpoint was reading higher than temperature. The problem was traced to an 
out-of-alignment temperature bridge card, which was replaced with a spare. Then 
psychrometer/MARS II comparisons were well within limits.

Visit 24-May-1995
TBRG installed for the summer.

WOY Wynard, SK 

Inspection 20-Jul-1994  
All instruments were cleaned and calibrated. The dewcel was changed. The 
amplifier in the videograph was replaced, and the videograph is now back in 
service.

Inspection 24-Nov-1994  
All instruments were cleaned and calibrated. The dewcel was changed. The aneroid 
barometer was replaced. The nipher shield was placed on the F&P, and it is now 
in service. The TBRG was removed for the winter.

WSZ Fisher Branch, MB 

Inspection 17-Mar-1993  
All instruments were cleaned and calibrated. Pressure averaged -0.25 mb 
different from the inspection barometer for 10 comparisons.

WEQ Swan River, MB

The autostation is located at the Swan River Airport in the Swan River Valley. 
Exposure is open in all directions.  Instruments are located on a level, grassed 
surface.  The Valley runs in a southwest to northeast direction with the 
Porcupine Mountains to the north-northwest and the Duck Mountains to the south-
southeast. The Valley bottom is fairly flat cropland with the occasional bluff 
of trees.

WDC Uranium City, SK

The instrument area is located on a 23-m-wide strip of grass running northeast 
from the airport terminal building.  This grassy area is sandwiched between a 
gravel vehicle parking area to the southeast and a paved aircraft parking ramp 
to the northwest.  The instrument exposure is fair, with some sheltering to the 
northeast by the Eldorado warehouse and to the west by the air terminal 
building.  Airflow from the north and south is generally unrestricted, although 
the south side of the instrument area is bounded by a 2-m security fence.  The 
instruments are subject to occasional "propwash" from aircraft in the parking 
area immediately to the north.  The airport is located approximately 15 km to 
the north of Lake Athabaska, and the surrounding countryside is quite hilly, and 
covered with evergreen and birch trees.  Numerous small lakes dot the area.

WJD Grand Rapids, MB

The site is located in the town of Grand Rapids, just north of the intersection 
of the main thoroughfare of the town and Highway #6.  Instrument exposure is 
very good.  Instruments are located in a 30-m-square area surrounded by a 1.2-m- 
high chain link fence.  Low brush has been cleared to a distance of 
approximately 60 m in all directions.  The surrounding terrain is flat, with 
mixed forest, scrub bush, and muskeg.  The mouth of the Saskatchewan River, 
where it flows into the north basin of Lake Winnipeg, is approximately 1 km to 
the southeast.  These two bodies of water, particularly open water on faster 
flowing sections of the river, contribute to high year-round humidities, 
frequent fog conditions, and heavy hoarfrost in the winter months.  The wind 
exposure is excellent in all directions because the 16-m wind mast extends well 
above the surrounding treetops.  In addition, the nearest tall trees (5-10 m) 
are at least 70 m away.

WOY Wynard, SK

The autostation is located at 505 5th St. W, at the corner of 5th St and Highway 
#16, in the southwest corner of the town of Wynard (population approximately 
2200).  The station is situated on a parcel of land that is approximately 98 m 
(north-south) by 152 m (east-west), grassed, and surrounded by a fence.  
Buildings from the former manned program are at the west end of the property, 
and the instruments are located in a 30-m by 30-m plot near the center of the 
property, with the wind tower near the east end.  The immediate surroundings 
are:  North - residential street, mostly one story single family dwellings; East 
- open school yard; South - Provincial Highway #16; and West - the local golf 
course.  Farther out to the north and east are residential and business 
districts. Farther to the south and west is mostly open crop and pasture land. 
The Quill lakes are located to the west and northwest, with the closest 
shoreline approximately 8 km away. These lakes are very shallow and can produce 
local low clouds during periods of northwest winds.  The local terrain is mostly 
gently rolling farmland, open except for an occasional farm shelterbelt or small 
wooded area in a depression. The topography has a gentle slope from the 
Touchwood Hills (elevation 670 m) some 10 km to the south, to the shores of the 
Quill lakes to the northwest (elevation 533 m).  The site offers an excellent 
exposure from all directions and is representative of the area.

WSZ Fisher Branch, MB

The station is situated at the southeast end of the 240 (north-south) by 90 
(east-west) m AES reserve. The instrument area is a 25 m square grass on gravel 
area in a rural setting and has good exposure. The reserve has been cleared of 
trees, but a line of trees borders the reserve on the western and northern 
edges. The surrounding countryside is generally flat farmland, with about 30% 
tree coverage. Lake Winnipeg lies about 50 km to the east and Lake Manitoba 
about 70 km to the west.

WVT Buffalo Narrows, SK

The autostation instruments are colocated with the manned site on a large (60 by 
60 m) grass-covered area surrounded by a wire security fence situated along the 
southwest side of the Buffalo Narrows airport. The airport is located on a broad 
peninsula that extends northeastward into Churchill Lake. Topography within a
30-km radius is 50% thickly treed bush and muskeg, and 50% large and small lakes 
of the Churchill River system. The wind tower is located near the runway, with 
open exposure in all directions.
