Hydrological Processes, 10:1565-1574.This data set comprises global, monthly satellite-derived Snow Water Equivalent (SWE) climatologies from November 1978 through May 2007, with periodic updates released as resources permit. Global data are gridded to the Northern and Southern 25 km Equal-Area Scalable Earth Grids (EASE-Grids). Global snow water equivalent is derived from Scanning Multichannel Microwave Radiometer (SMMR) and selected Special Sensor Microwave/Imagers (SSM/I). Northern Hemisphere data are enhanced with snow cover frequencies derived from the Northern Hemisphere EASE-Grid Weekly Snow Cover and Sea Ice Extent Version 2 data (these data were not produced for the Southern Hemisphere). The data are binary data files and PNG images, and are available via HTTPS.VIEW RELATED INFORMATIONhttps://nsidc.org/sites/default/files/nsidc-0271-userguide-v1_1.pdfGlobal Monthly EASE-Grid Snow Water Equivalent Climatology, Version 1 User GuideGET DATAhttps://daacdata.apps.nsidc.org/pub/DATASETS/nsidc0271_monthly_ease_grid_swe/HTTPSVIEW RELATED INFORMATIONhttp://nsidc.org/data/nsidc-0046.htmlNorthern Hemisphere EASE-Grid Weekly Snow Cover and Sea Ice Extent Version 3CEOS IDN DIFVERSION 9.92005-05-312026-01-26NSIDCVersion SummaryInitial releaseNSIDCMinor VersionNSIDCCurrent Version1NSIDCSpatial Reference SystemsEPSG:3408NSIDC EASE-Grid NorthEPSG:3409NSIDC EASE-Grid SouthNSIDCLevel of ServiceBasicNSIDCFull Dataset CitationArmstrong, R., Brodzik, M.
