Overview

This data set is a daily gridded terrestrial snow water equivalent (SWE) dataset based on five component SWE products:

GlobSnow combined SWE product (passive mircowave/ground-based weather station, version 2)
ERA-Interim/Land reanalysis SWE product
MERRA reanalysis SWE product
Crocus SWE data set: output from the Crocus snowpack model, driven by ERA-Interim meteorology (Brun et al. 2013)
GLDAS SWE product (version 2) (Rodell et al. 2004; Rodell and Beaudoing 2013)
