在提取ＧＭＳ－４红外通道晴空亮温的基础上，用３种方法对１９９３年８月西北太平洋海温进行了反演试验。误差放大的内在特性使得单通道物理法误差显著，所以，建立了一个单通道统计方法，精度（１．１８℃）上优于同类方法；还将ＴＯＶＳ资料与ＧＭＳ资料结合起来，建立海温多通道统计反演方法，精度（１．０６℃）达到了当代同类方法的精度（０．５—１．３６℃）。两种统计方法得到了与实况相近的海温反演分布
On the basis of extracting the bright and clear temperature of GMS-4 infrared channel, three methods were used to invert the SST of the Northwest Pacific Ocean in August 1993. Therefore, a single-channel statistical method is established with accuracy (1.18 ℃) superior to similar methods. The TOVS data is also combined with GMS data to establish the SST Channel statistical inversion method, accuracy (1.06 ℃) reached the accuracy of contemporary methods (0.5-1.36 ℃). Two statistical methods have been obtained with the inversion of the sea temperature inversion distribution
