By using MODIS images of EOS satellite as data source，and taking coas tal region of Fujian as a demonstration site, the retrieval experiment of sea su rface temperature was carried out based on MODIS multichannel data，and the pr e cision of MODIS sea surface temperature was verified and analyzed with measureme nts of ten stations in coastal region of Fujian during 2003-2004. The average ab solute error of sea surface temperature calculated by MODIS data was 0.75℃ ，the standard error was 0.52℃，the samples of absolute error within 1.0℃ was 68% o f total samples. The results showed that the accuracy of sea surface temperature calculated by MODIS data in coastal region was equivalent with the accuracy of sea surface temperature calculated by NOAA/AVHRR data.
