A legacy of snow science community: 40-years gamma SWE record

November 9, 2020 |

In the western U.S., 85% of freshwater runoff originates as snowmelt. In the north-central and northeast U.S., most significant floods of the 20th century were directly related to snowmelt. Thus, accurate, timely estimates of the snowpack are required to help monitor and manage seasonal snow and melt.
