Manual snow survey sampling from snow courses consisting of 10 measurement points. Measurements of snow water equivalent (SWE), and snow density are expressed as an average across the snow course. Measurements are taken three times a year at the start of March, April , and May.

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Snow cover indicators show how Canada's snow cover is changing from year-to-year and over time. Snow cover extent is expressed in millions of square kilometres and is presented for the spring months of April, May and June. Sixty-five (65) percent of Canada's land mass has annual snow cover for more than 6 months of the year.

This dataset corresponds to daily snow cover percentage at 1km resolution grid over land areas of Canada from 2006-2010. The data are subsampled by 4km to reduce data volumes and considering the geolocation uncertainty of the input satellite imagery. The daily maps are generated by assimilation of daily cloud screened NOAA AVHRR satellite imagery and Canadian Meteorological Centre (CMC) snow depth analysis snow depth and density fields within an off-line version of the CMC daily snow depth model. The snow depth model is modified to include snowpack reflectance model and a surface radiative transfer scheme that relates vegetation and snowpack reflectance to top-of-canopy bi-directional reflectance.

Permafrost and snow are critical to the ecology of many northern ecosystems. They influence hydrology and vegetation and can dramatically affect the quality of wildlife habitat. In recent decades permafrost temperatures in North America have increased and snowfall and spring snow cover in the Arctic have declined. These trends are predicted to continue, although with regional and seasonal variability.

Snow and ice are important hydrological resources. Their minimum spatial extent here referred to as annual minimum snow/ice (MSI) cover, plays a very important role as an indicator of long-term changes and baseline capacity for surface water storage. The MSI probability is derived from sequence of seventeen 10-day clear-sky composites corresponding to April, 1 to September, 20 warm period for each year since 2000. Data from Moderate Resolution Imaging Spectroradiometer (MODIS) on Terra satellite for the period since 2000 have been processed with the special technology developed at the Canada Centre for Remote Sensing (CCRS) as described in Trishchenko, 2016; Trishchenko et al., 2016; 2009, 2006, Khlopenkov and Trishchenko, 2008, Luo et al., 2008.

In situ observations of snow water equivalent (SWE) from manual snow surveys and automated sensors are made at ~1000 sites across Canada in support of water resource planning for flood control and hydroelectricity production. These data represent an important source of information for research (e.g. validation of hydrological and climate model models), for applied studies (e.g. snow loads) and for climate monitoring.
