Abstract

We consider an advanced variant of an electromagnetic model of a rough surface with the goal to provide numerical modeling of the salinity-temperature radiometric contrasts. These calculations are made especially at the wavelength of 21 cm (14.3 GHz) and the nadir incidence angle for low-wind (<7 m/s) and foam-free sea conditions. In these cases, passive microwave radiometric measurements perhaps are the best suited for the sea salinity mapping and the retrieval is quite accurate. Some numerical examples of salinity radiometric effects are presented
