Abstract :
A sea surface temperature (SST) retrieval methodology based on thermal infrared radiometric measurements from an oil-rig is proposed in order to achieve a precision better than ± 0.3 K. This precision was required for accurate sea surface salinity determination within the WISE campaigns. Possible error sources in the radiative transfer equation are identified to determine the best possible measurement conditions and radiative data corrections. This method permits us to obtain the SST with a precision of ± 0.18 K and an accuracy of 0.0 ± 0.2 K.
