Abstract

WindSat is the first spaceborne fully polarimetric microwave radiometer. We describe a nonlinear optimization algorithm for WindSat wind vector and sea surface temperature retrievals. The algorithm simultaneously retrieves the atmospheric water vapor and cloud liquid water, sea surface temperature and the ocean surface wind vector that matches our forward model to the measured brightness temperatures. The forward model is based on parameterizations of a radiative transfer model with empirical corrections. We describe our retrieval algorithm and present analysis of retrieval performance
