The effect of sea surface temperature (SST) on sea surface brightness temperature measured by L-band microware radiometers is estimated in this paper. We found systematic SST dependence in Aquarius radar backscatter σ 0 , radiometer excess emissivity Δe as well as sea surface excess brightness temperature Δ Tb . The influences of SST on σ 0 , Δe and Δ Tb in cold water are much more bigger than that in warm water. The precision of the corrected measured flat sea surface bright temperature is improved significantly after correcting with SST.
