Microwave Signatures of Sea Ice Based on Airborne Radiometer Measurements
Airborne measurements carried out with a radiometer system at 5, 17 and 34 GHz in the Greenland area have been used for derivation of sea ice signatures. A fixed, profiling antenna system, having equal, overlapping footprints, was used on some flights, while a scanning antenna producing high resolution imagery, was used on others. A great variety of sea ice conditions have been experienced: different ice concentrations, large single floes of first-year ice and multiyear ice, thin new ice and various combinations of these ice types.
