A method for Sea Surface Temperature: SST estimation with thermal infrared radiometer data by means of non-linear iteration is proposed. Although it is essential that SST is estimated by solving of radiative transfer equation: RTE, it is not so easy to solve the equation because of a non linearity of the equation. In the proposed method, RTE is symplified and is solved with a iterative method such as Conjugate Gradient method, etc. Through a comparison of the Root Mean Square error of the proposed method with that of the well known Split Window method, it is found that 7.9 to 56.3% of improvement can be achieved by the proposed method for 1350 of atmospheric and ocean surface parameters for the MODTRAN 3.7. Further, the proposed method is applied to the ADEOS/OCTS data. It is also found that RMS error of the proposed method is around 0.382 [K] .
