Abstract  

This paper proposes a regional algorithm to estimate sea surface temperature (SST) in the East China Sea has been developed using MODIS data aboard Terra and the coefficients of the algorithm were ascertained using MODTRAN 4.0 code and TIGR profiles.The East China Sea's 24 profiles were chosen from TIGR database to input the MOTRAN4 code to calculate the at sensor apparent brightness temperatures in MODIS band 20,29,31 and 32 under 21 observation angles (from 0 to 65 degree) and the coefficients were obtained from the 3,528 samples using the least square method.The preliminary results show a good agreement between SSTs estimated by the proposed algorithm for Terra MODIS data and MODIS SST products.The comparison of the SSTs estimated by the proposed algorithm with concurrent in situ data showed an accuracy of about 1K.With observation angles increase the accuracy deduced from 0.68K to 1.16K.The accuracy of the proposed algorithm was better than that used in MOD28.Our future work would be conducted to collect more profiles and in situ data and improve the accuracy of our algorithm in large observation angles.
