摘要

一般认为，获取海面盐度(SSS)的最佳方法是l波段辐射测量(1400-1427 MHz)。然而，除了极化和入射角、SSS和海表温度(SST)外，海表亮温还取决于海况。这项工作描述了一种混合的l波段辐射计和GPS L1反射计，提出了在类似的表面粗糙度尺度上推断海况信息，从而提高海况在表面盐度估计中的校正。

PAU in SeoSAT: A proposed hybrid L-band microwave radiometer/GPS reflectometer to improve Sea Surface Salinity estimates from space

It is generally accepted that the best way to retrieve sea surface salinity (SSS) is by means of L-band radiometry (1400-1427 MHz). However, in addition to the polarization and the incidence angle, the SSS and the sea surface temperature (SST), the sea surface brightness temperature depends on the sea state. This work describes a hybrid L-band radiometer & GPS L1 reflectometer proposed to infer sea state information at similar surface roughness scales and therefore improve the sea state correction in surface salinity estimates.
