Description:

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.
