| 摘 要： | Sea surface salinity (SSS) plays an important role in the sub-polar area, where intrusions with low salinity influence the deep thermohaline circulation and the meridional heal transport. SSS fields and their seasonal and inter-annual variability are thus…

| Abstract: | Using the small-slope approximation model of microwave emission of rough sea surface, the impacts of sea surface wind on brightness temperature variations generated by the surface roughness, i.e. ΔT h,v, are investigated. Here ΔT denotes the brightness temperature variation, and “h” and “v” denote the horizontal and vertical polarizations respectively. ΔT h,v has a linear relation with wind speed, sea surface temperature (SST) and sea surface salinity (SSS) respectively. Further more, the impact of wind direction on SSS retrieval, under small incidence angles, can be removed by calculating (ΔT h+ΔT v). These characteristics provide simple new ways to develop an SSS retrieval algorithm without wind direction factor. |
