The moderate resolution atmospheric radiance and transmission (MODTRAN), with the input parameters obtained from Terra/MODIS (moderate resolution imaging spectroradiometer), was used to calculate the atmospheric effect parameters, including atmospheric transmittance, upward radiance and downward radiance. Combined with the sea surface emissivity provided by the Jet Propulsion Laboratory (JPL) and spectral response functions for five bands of advanced spaceborne thermal emission and reflection radiometer (ASTER) sensor, the sea surface temperatures (SST) were solved from radiative transfer equations pixel by pixel for each band. If the difference between any two bands’ SSTs for the same pixel is less than 0.5K, the average of five bands’ SSTs of the pixel was taken as true SST, which was then used to derive the undetermined coefficients of Split-Window algorithm. Finally, the Split-Window algorithm was applied for the SST retrieval. The results showed the algorithm has good accuracy. The SST values retrieved from ASTER data acquired on October 20, 2007 were compared to the MODIS SST, which gives the mean deviation of 0.35℃ and the root-mean-squared error (RMSE) of 0.49℃. The same procedure was repeated for ASTER data acquired on May 15, 2008, which gives the mean deviation of 0.38℃ and RMSE of 0.52℃.
