The SST operational retrieval algorithm has been derived and validated for FY-3A. Using long time series of in-situ measurements data and coincide/collocated FY-3A VIRR sensor data collected in the Bohai Sea and northern Yellow Sea, we proposed a split-window algorithm suitable for FY-3A VIRR SST retrieval. Validation against independent data shows the mean deviation between satellite and matchup in-situ measurements was 0.78 ℃ with a RMSE of 0.93.
