Quantitative Evaluation of Ocean Surface Spectral Model Influence on Sea Surface Backscattering

Abstract

Sea surface backscattering in the microwave region is evaluated for three ocean surface wavenumber spectral models using the composite surface method. The three ocean surface spectral models considered are a power law spectrum, the Durden-Vesecky spectrum and the Apel spectrum. Backscattering results obtained for the power law spectrum are found to be in good agreement with those calculated using a small slope approximation method. Backscattering results obtained for the Durden-Vesecky and Apel spectral models are also compared with three empirical scattering models (CMOD2-I3, SASS-II and NSCAT-I). In general, the empirical scattering models fall between the predictions of the Durden-Vesecky and Apel spectra.
