Description
The Canadian Daily Snow Depth Database consists of daily ruler measurements of snow depth taken by Meteorological Service of Canada observers. The depth data extends from the late 1800s to early 1996 in the database, although most of the data are in the period after 1950. Daily snow depth data from the National Climate Data Archive have been included on the CD-ROM for the 1996-1999 period to provide users with the capability of updating information to the end of the 1998/1999 snow season.
The Canadian Snow Water Equivalent Database contains snow water equivalent (SWE) and snow depth measurements from snow surveys taken by more than twenty agencies at weekly, biweekly or monthly frequencies. The data cover the period from the mid-1950s to the mid-1990s, with a pronounced peak in the 1976-1985 decade. At peak levels in the early 1980s, there were over 1700 snow course observations per year in the database. This number declined to around 800/year in the early 1990s. In many cases, updates to the snow course data contained in this CD-ROM can can be readily obtained from the various provincial agencies involved in taking snow surveys.
