A full-Stokes vector model for the microwave emissivity of an anisotropic wind driven ocean surface based on measured satellite data and using a two-scale model for surface emission is being developed for the purpose of assimilation of satellite microwave radiances. The model is based on the Ohio State University two-scale model and tuned to WindSat full-Stokes emissivity data as analyzed by Meissner and Wentz. Several physical inconsistencies were corrected in the model. The tuned model results over a range of wind speeds from 0-20 m/sec show good agreement in the 0th, 1st, and 2nd azimuthal brightness temperature harmonics. A bias model for the tuned model was developed to account for residual discrepancies.
