Abstract :
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.
