The Daily 4 km Gridded SWE and Snow Depth from Assimilated In-Situ and Modeled Data over the Conterminous US, Version 1 data set, accessible from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated. New data have been added so the data set now spans 1 October 1981 to 30 September 2020. This data set provides daily 4 km snow water equivalent (SWE) and snow depth over the conterminous United States from 1981 to 2020, developed at the University of Arizona (UA) under the support of NASA MAP and SMAP Programs.
