Abstract

This paper proposes an efficient way to retrieve the microwave emissivity from advanced microwave sounder unit (AMSU) brightness temperature measurements. In the first step, the atmospheric temperature profile, moisture profile and surface skin temperature are determined using AMSU channel 5 to 14, 18 and 19 which are less sensitive to surface radiation. In the second step, the microwave emissivity is then determined using the AMSU window channel 3. Finally, the atmospheric profile and the microwave emissivity are retrieved simultaneously based on a non- linear iteration algorithm using all AMSU and high resolution IR radiation sounder measurements. Simulation results have shown this algorithm is practical in solving for the microwave emissivity. This algorithm will be part of the International ATOVS Processing Package developed by Cooperative Institute for Meteorological Satellite Studies, University of Wisconsin-Madison.
