Error Analysis of Sea Surface Temperature Retrieved From the HY-1 Satellite Data

In this paper,the estimated error of sea surface temperature(SST) retrieved from the HY-1 sate-(llite) data are analyzed by using GTS ship report SST data and NOAA satellite SST data,respectively.It is shown from the analysis results that the RMS error between HY-1 satellite SST data and NOAA satellite SST data is 0.94 ℃.The main factors affecting the accuracy of the HY-1 satellite SST are the atmospheric water vapor absorption and cloud cover.In addition,the techniques of atmospheric correction and cloud detection for retrieving SST from satellite data are also discussed.
