Abstract

A theoretical assessment has been made on the relationship between the number of chan-nels used and the accuracy of remotely measured sea surface temperature (SST) by multi-channel radiance observations from satellite. It has been shown that the accuracy of SST continuously increases with the increase of the number of channels. The accuracy also depends on the accuracy of they clear radiance, accuracy of the initial guess of the SST and transmittance of the atmosphere.A procedure of the objective analysis for the SST has been developed and applied to the analysis of the SST that is obtained in Meteorological Satellite Center (MSC) on routine base from NOAA-6 meteorological satellite. The results has been compared with buoy and ship reports of SST and the GOSSTCOMP sea surface temperature made by NOAA/NESS. Root-mean-square deviation of satellite derived SST from ship reports is about 0.8°K.
