Characteristics include the location of sea ice cover, sea ice age, day of melt onset, and status of melt onset. Data are gridded in the 25 km Equal-Area Scalable Earth Grid (EASE-Grid) 2.0 and provided as netCDF files.VIEW RELATED INFORMATIONhttps://nsidc.org/sites/default/files/nsidc-0532-v001-userguide.pdfMEaSUREs Arctic Sea Ice Characterization Daily 25km EASE-Grid 2.0, Version 1 User GuideGET DATAhttps://search.earthdata.nasa.gov/search/granules?p=C3291000765-NSIDC_CPRDEarthdata SearchGET DATAhttps://cmr.earthdata.nasa.gov/virtual-directory/collections/C3291000765-NSIDC_CPRDHTTPSGET DATAhttps://nsidc.org/data/data-access-tool/NSIDC-0532/versions/1/Data Access ToolGET DATAhttps://earthaccess.readthedocs.io/en/stable/earthaccessCEOS IDN DIFVERSION 9.92014-06-192026-08-27NSIDCVersion SummaryInitial releaseNSIDCMinor Version1Data type of latitude/longitude arrays changed to float (IEEE single-precision floating point); DOI corrected in metadata; v01.r01 appended to data files.
