Abstract :
This paper presents sea ice environmental parameter retrieval algorithms using data from WindSat, a fully polarimetric passive microwave radiometer. Sea ice concentration and age are retrieved from WindSat data by adapting NASA-TEAM (NT) algorithm, which has been operationally used for special sensor microwave/imager (SSM/I). The tie-points and weather filters are modified. The modified NT algorithm includes sea ice climatology and land contaminations. We develop an alternative algorithm to retrieve snow-layered sea ice in the Southern Hemisphere as a proxy to the enhanced NT (NT2) algorithm. We also develop algorithms using WindSat 10.7 GHz channels. Preliminary results show that modified NT and proxy NT2 algorithms work compatibly well with NT and NT2 algorithms, respectively.
