- Abstract
- A full-Stokes vector model for microwave ocean surface emissivity based on two-scale theory and incorporating a wide range of published results is being developed for broadband microwave satellite data assimilation. The model is based on the six different modules such as ocean surface permittivity, Fresnel emission, omnidirectional wave height spectrum, small-scale perturbation, large-scale correction, and foam effect modules. The results showed that the calculated Full-stokes emissivities range in theoretically expected values and logically understandable variation with respect to incidence and azimuth angle. This model will be used for understanding of the emissivity uncertainties due to inputs of permittivity, ocean height distribution, and foam influences and for assimilation of fully-polarimetric satellite microwave radiances.
