Two of the variables are derived from individual source products: the NOAA/NCDC Northern Hemisphere Snow Cover Extent Climate Data Record and Defense Meteorological Satellite Program (DMSP) passive microwave brightness temperatures, respectively. The third variable merges the other two into a single representation of snow cover.VIEW RELATED INFORMATIONhttps://nsidc.org/sites/default/files/nsidc-0531-v001-userguide.pdfMEaSUREs Northern Hemisphere Terrestrial Snow Cover Extent Weekly 100km EASE-Grid 2.0, Version 1 User GuideGET DATAhttps://search.earthdata.nasa.gov/search/granules?p=C3291000593-NSIDC_CPRDEarthdata SearchGET DATAhttps://cmr.earthdata.nasa.gov/virtual-directory/collections/C3291000593-NSIDC_CPRDHTTPSGET DATAhttps://nsidc.org/data/data-access-tool/NSIDC-0531/versions/1/Data Access ToolGET DATAhttps://earthaccess.readthedocs.io/en/stable/earthaccessCEOS IDN DIFVERSION 9.92014-12-162026-03-03NSIDCVersion SummaryInitial releaseNSIDCMinor Version1Added 1D arrays named cols and rows that contain x and y coordinates (meters from origin) of the projection; v01r01 appended to new data files.0NSIDCCurrent Version1NSIDCSpatial Reference SystemsEPSG:6931WGS 84 / NSIDC EASE-Grid 2.0 NorthNSIDCLevel of ServiceStandardNSIDCFull Dataset CitationRobinson, D.
