Three sets of satellite-derived SST products(CRW SST,OSTIA SST and RSS SST)are compared and evaluatedduringtyphoonprocessesintheSouthChinaSea.Theresultsshowthatallthreeproductscancapture the spatial-temporal variation of SST in typhoon-affected sea area.The difference between the CRW and OSTIA products is small(root mean square error is 0.22℃,correlation coefficient is 0.97),and the local SST in the RSS product decreases significantly after typhoon process.The root mean square errors of the CRW,OSTIA and RSS products with respect to buoy data are 1.27℃,1.32℃and 1.00℃,respectively.In summary,the RSS product performs best on SST variance during typhoon processes in the South China Sea.
