- Statement
-
This level 3 product contains arctic polar sterographic 25 km resolution grids of backscatter coefficient over sea-ice from AMI-Wind scatterometers onboard ERS at different incidence angles. The grids are derived from weekly averaged 50 km resolution swath sigma-naught data (from WNF product distributed at CERSAT) and spatially interpolated by a kriging method. The ERS radar backscattering properties enable the monitoring of sea-ice extent and edges (by discriminating open water from sea-ice) but also the categorization of polar sea-ice as : multi-year ice, consolidated first-year ice, or marginal ice. The product includes for each pole the following maps : sea-ice backscatter at 40° and 50° incidence, backscatter derivative at 28° and sea-ice/water mask. The dataset covers the complete ERS-1/-2 mission.
