Inversion of sea surface temperature (SST) with geostationary meteorological satellite (GMS) data has always been based on single infrared channel data. The wavelength of Japan GMS-5 infrared division window channel and of NOAA polar-orbiting weather satellite infrared channel show no difference. Beginning with the S-VISSR image position and data calibration and referring to multichannel SST(MCSST) technology of polar-orbiting satellite, the inversion of SST in 117. 140°E and 25°—45°N area is tried according to the GMS-5 data. Methods of inversion SST with GMS multichannel data are discussed.
