Researchers at Concordia have developed a new method of measuring the amount of usable water stored in snowpacks. The comprehensive technique, known as snow water availability (SWA), uses satellite data and climate reanalysis techniques to calculate snow depth, snow density and snow cover across a wide swath of Canada and Alaska. “SWA quantifies how much water is available where snowpack exists. Data gathered using this methodology shows that usable snow water has declined sharply in areas of the Canadian Rockies, where major river headwaters originate.
