Correcting SeaWinds scatterometer measurements for atmospheric attenuation

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/sub ex/ to evaluate the attenuation. The excess temperature T/sub 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.
