  1. USING SMOS POLARIMETRIC BRIGHTNESS TEMPERATURES TO CORRECT FOR ROUGH SURFACE EMISSION BEFORE SALINITY INVERSION

  2. COMBINING HORIZONTALLY AND VERTICALLY POLARIZED BRIGHTNESS TEMPERATURES TO REMOVE SSS DEPENDENCE

  3. COMBINING HORIZONTALLY AND VERTICALLY POLARIZED BRIGHTNESS TEMPERATURES TO REMOVE SSS DEPENDENCE The relative sensitivities of horizontally and verticallypolarizedbrightnesstemperatures to changes in salinity and wind speed are differentat large incidence angles. Wewill exploit thisdifferenceto derive the windfrom a linearcombination of Th and Tv thatisinsensitive to salinity changes and then use thiswind to derivesalinityusing the first Stokes parameter.
