The AMSR-E/AMSR2 Unified Level-3 25 km product provides sea ice concentration derived from brightness temperatures using the NASA Team 2 (NT2) algorithm for the Northern and Southern Hemisphere. This data set includes six daily brightness temperature fields for channels ranging from 6.9 through 89.0 GHz, three daily sea ice concentration fields, and three daily sea ice concentration difference fields for ascending orbits, descending orbits, and full orbit daily averages. The sea ice concentration difference fields compare the NT2 algorithm with the Bootstrap algorithm. All fields are mapped to 25 km polar stereographic grids.
<b>Note:</b> This product uses the Japan Aerospace Exploration Agency (JAXA) AMSR2 Level-1R input brightness temperatures that are calibrated, or unified, across the JAXA AMSR-E and JAXA AMSR2 Level-1R products.VIEW RELATED INFORMATIONhttps://doi.org/10.5067/TRUIAL3WPAUPDocumentationGET DATAhttps://n5eil01u.ecs.nsidc.org/AMSA/AU_SI25.001/HTTPSGET DATAhttps://search.earthdata.nasa.gov/search?q=AU_SI25+V001Earthdata SearchGET RELATED VISUALIZATIONhttps://worldview.earthdata.nasa.gov/?p=arctic&l=BlueMarble_NextGeneration,AMSRU2_Sea_Ice_Concentration_25km,CoastlinesWorldviewGET DATAhttps://nsidc.org/data/data-access-tool/AU_SI25/versions/1/Data Access ToolPROJECT HOME PAGEhttps://nsidc.org/data/amsre_amsr2AMSR-E Website at NSIDCARCTIC, Amd, ceosCEOS IDN DIFVERSION 9.92018-09-202023-11-15NSIDCVersion SummaryNSIDCMinor VersionNSIDCCurrent Version1NSIDCSpatial Reference SystemsEPSG:3411NSIDC Sea Ice Polar Stereographic NorthEPSG:3412NSIDC Sea Ice Polar Stereographic SouthNSIDCLevel of ServiceComprehensiveNSIDCFull Dataset CitationMarkus, T., J.
