Published by NASA NSIDC DAAC;UAZ/ATMOS | National Aeronautics and Space Administration | Catalog Last Checked: July 28, 2026 at 10:44 PM | Dataset Last Updated: June 23, 2026
This data set provides daily 4 km snow water equivalent (SWE) and snow depth over the conterminous United States. It was developed at the University of Arizona (UA) under the support of the NASA MAP and SMAP Programs. The data were created by assimilating in-situ snow measurements from the National Resources Conservation Service's SNOTEL network and the National Weather Service's COOP network with modeled, gridded temperature and precipitation data from PRISM.
