This file contains a composite of Synthetic Aperture Radar (SAR) derived sea ice classification covering the Arctic for a period of one day. The files are produced in SAROPS (SAR Operational Product System) by the Water Surface Conditions science team within the NOAA STAR Satellite Oceanography and Climatology Division. Data from the following C-Band SAR systems are included: Sentinel-1, RADARSAT-2, and RADARSAT Constellation Mission. Sea ice classification values represent concentration up to 80%, and greater than 80%. Daily coverage varies depending on SAR acquisitions.
Class variable includes 5 discrete numerical values (0, 1, 3, 8) corresponding to: No Data (0), Water (1), ice concentration less than about 80% (i.e. MIZ) (3), ice concentration less than about 80% (i.e. pack ice) (8)
