Data set update: Daily 4 km Gridded SWE and Snow Depth from Assimilated In-Situ and Modeled Data over the Conterminous US, Version 1

The temporal coverage of 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 through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been extended to include the 2021 water year. This data set provides daily 4 km snow water equivalent (SWE) and snow depth over the conterminous United States from 1981 to 2021, 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.
