Abstract

An attenuation-correction algorithm for the SeaWinds instrument uses the AMSR brightness temperature to find the attenuation experienced by the scatterometer signal. The algorithm uses the concept of excess temperature T_ex to evaluate the attenuation. The excess temperature T_ex is the difference between the measured brightness temperature and the temperature of the emitting surface. The algorithm uses an iterative scheme. Simulation results show obvious improvement on the scatterometer measurements
