Abstract

We present a method for evaluating characteristics of wind vector retrieval error´s from polarimetric radiometer measurements such as WindSat. Focus is put on moving wind direction errors due to ambiguous solutions, with azimuth angle being 0 and 180. We propose a method to obtain wind direction according to first and second rank solutions of the first scan and first rank solution of the second scan. This algorithm can avoid ambiguous solution.
