CanSISE Observation-Based Ensemble of Northern Hemisphere Terrestrial Snow Water Equivalent, Version 2

This data set is a daily gridded terrestrial snow water equivalent (SWE) dataset based on five component SWE products: 1) GlobSnow combined SWE product (passive microwave/ground-based weather station, version 2) at http://www.globsnow.info. 2) ERA-Interim/Land reanalysis SWE product at http://apps.ecmwf.int/datasets/. 3) MERRA reanalysis SWE product at http://gmao.gsfc.nasa.gov/pubs/docs/Reichle541.pdf. 4) Crocus SWE data set (Brun et al. 2013): output from the Crocus snowpack model, driven by ERA-Interim meteorology (https://doi.org/10.1175/JHM-D-12-012.1). 5) GLDAS SWE product (version 2): Rodell et al. 2004 (https://doi.org/10.1175/BAMS-85-3-381); Rodell and Beaudoing 2013 (https://doi.org/10.5067/0JNJQ8ZDZRBA).
