This dataset consists of a total of seven files, for five weather station
locations along the BOREAS transect in Canada.  Each file contains the climate
values for each month and for each year of the station's history.  Variables
reported include total precipitation, mean daily minimum and maximum
temperature for all stations, and three solar radiation measurements for
several stations.  These stations are:

   Churchill       - tundra on Hudson Bay coast
   Thompson        - in forest, towards northern limit
   Flin-Flon       - mid-transect
   Prince Albert   - near southern limit of forest
   Medicine Hat    - grassland, well to southeast of forested region.

   Churchill and Medicine Hat fall outside the main transect area, but
within the "extended" transect. The middle three stations provide a
reasonable range of conditions within the core transect.

   Churchill and Prince Albert stations have moved during the recording
period, and are in two files. Thompson is a pretty short record.

   The files are in a format where each file begins with a line that contains
the AES station ID number and name, latitude and longitude, and the period of
record.  The period of record is given in two forms: the first is the AES
claim, and the second is the actual period found in the file (listed as first
year, last year, then first month {of the first year} and last month {of the
last year}).  The second line of each file provides column headings.  Always
present are year, month, mean daily minimum temperature for the month (C),
mean daily maximum, and total precipitation (mm).  Some files may also have
bright sunshine hours, sunshine hours as a percentage of daylight hours, and
solar radiation (mean daily total, in MJ/sq.m).  Each following line is one
monthly set of values.  Missing data is coded as -99.999.
