Mean Annual Total Precipitation Contained within the 3rd Edition (1957) of the Atlas of Canada is a plate that shows two maps for the annual total precipitation. Annual precipitation is defined as the sum of rainfall and the assumed water equivalent of snowfall for a given year. A specific gravity of 0.1 for freshly fallen snow is used, which means that ten inches (25.4 cm) of freshly fallen snow is assumed to be equal to one inch (2.54 cm) of rain. The mean annual total precipitation and snowfall maps on this plate are primarily based on thirty-year data during the period 1921 to 1950 inclusive. 1957-01-01 2017-01-26 Natural Resources Canada NRCan.geogratis-geogratis.RNCan@canada.ca Nature and EnvironmentScience and Technologyclimateclimate archivesmeteorological datameteorologyprecipitationsnowweather Download the English JPG through HTTPJPG http://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/atlas_3_ed/eng/environment/climate/025.jpg Download the English PDF through HTTPPDF http://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/atlas_3_ed/eng/environment/climate/025.pdf Download the French JPG through HTTPJPG http://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/atlas_3_ed/fra/environment/climate/025.jpg Download the French PDF through HTTPPDF http://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/atlas_3_ed/fra/environment/climate/025.pdf
