摘　　要：建立适于FY-3A卫星的海表温度业务化反演算法并验证其精度.采用覆盖我国渤海及北黄海的长时间序列现场观测数据及相应FY-3A VIRR数据,建立了适于FY-3A VIRR海表温度反演的分裂窗算法.独立样本数据验证表明,算法平均误差为0.78℃,RMSE为0.93.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 meastlrements was 0.78 ℃ with a RMSE of 0.93.
