6.2.2 Snow Water Equivalent (SWE) product

Snow water equivalent (SWE) estimates have widespread applications in hydrology, agriculture, and emergency management.

This example, created from satellite and surface observations of SWE, shows snowpack conditions during late winter in the CONUS. Notice the high SWE values over the western mountain ranges and the extreme northern parts of New England, and the lower values (10 to 15 cm or 4 to 6 in) over some of the flatter areas of the northern fringes of the U.S.
