Abstract

The atmosphere influence on sea-surface emission is discussed in the context of passive microwave polarimetry application for surface wind vector retrieval. Two aspects of the problem are considered. First, the atmosphere stability affects sea surface roughness and therefore its emissivity. This dependence restricts the accuracy of wind speed retrieval algorithm. A feasible way of algorithm correction is proposed. The second issue addressed is atmospheric attenuation of microwaves. A simplified radiative transfer equation is used to estimate this effect, and to correct wind retrieval algorithm for atmospheric attenuation
