Global Sea Ice TypeOperational Near real time product
Ice classes are assigned from atmospherically corrected SSMIS brightness temperatures and ASCAT backscatter values, using a Bayesian approach. Both the sea ice edge product and the sea ice type product are classification products differing between different ice classes. Sea ice type differs between First-year ice and Multiyear ice which are defined from target regions of known ice types. The product series is operational since 2005 (version OSI-403-b since 15/09/2015, version OSI-403-c since 30/05/2017).
