CS2/SMOS NRT Sea-Ice thickness
Sea ice thickness (SIT) is calculated by merging Cryosat-2 altimeter and Soil Moisture and Ocean Salinity (SMOS) radiometer measurements. The combination of both datasets is based on an algorithm developed at the Alfred Wegener Institute. It uses a statistical approach (optimal interpolation), which merges weekly information from CryoSat-2 and SMOS based on the respective uncertainties for different thickness classes. The product contains the sea ice thickness for each calendar week on the 25 km EASE2 Grid.
