Abstract:

The 89 GHz channels of the passive microwave sensor AMSR-E have more than twice the horizontal resolution of its other lower frequency channels. The retrieval of total ice concentration based on the 89 GHz channels was well established,while retrieval of the multiyear ice concentration was little explored until now. The brightness temperatures of the AMSR-E 89 GHz channels are used to characterize their response to multiyear ice,first-year ice and open water. A simple algorithm,called Algorithm Currently (A...
