摘要 分别利用GTS船舶报海温数据和NOAA卫星海温数据分析了HY-1卫星海温反演误差。结果显示,对于GTS海温数据,RMS为1.26℃;对于NOAA卫星海温数据,RMS为0.94℃。影响HY-1卫星海温反演精度的主要因素为大气中的水汽吸收和云覆盖。另外,对HY-1卫星海温反演中的大气校正和云检测技术的改进进行了探讨。 In this paper, the estimated error of sea surface temperature(SST) retrieved from the HY-1 satellite 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.
