中文摘要:
      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着,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。
英文摘要:
      On the basis ofextracting the clear brightness temperature in GMS-4 infrared data, the tests have been carried out by using three methods for SST retrieval in the North-western Pacific Ocean in August 1993.Considering error amplification is the inherent nature in the single channel physical method,two statistical methods are developed. One is a sing le channel method.Its precision is 1.18℃,which is superior to that ofother similar methods.The otheris a multi-channel method using both TOVS and GM S-4 data.Its precision is 1.06℃,which is matched with that of other current multi-channel statistical methods(0.5-1.36℃).The retriev al SST distributions obtained by the two methods are in good agreement with real observations.
