摘要: 利用TRMM卫星和GMS-5卫星的两个红外分裂窗通道的亮温资料,结合淮河流域能量与水分试验(HUBEX)加密观测期间获得的地面温度的观测资料,建立了反演淮河流域地面温度的参数化方程。结合地面观测站的资料,分别从不同的角度对TRMM和GMS卫星反演的结果做了检验,得到的反演结果比较接近于实际情况。最后结合1998年淮河流域试验加密观测期间的主要天气形势,分析了江淮梅雨4个阶段相对应的地面温度的特征。

Abstract: The equation for estimating land surface temperature of Huaihe River Basin has been set up by using the data of split window channels of TRMM and GMS-5 satellite and the ground observation data of HUBEX. Comparison with the ground observation data of Huaihe River Basin from many aspects shows the result is in good agreement with observation. On the basis of the typical weather situation in Huaihe River Basin in 1998, the paper analyses the features of the land temperature of Huaihe River Basin in the four stages of the 1998's Meiyu of Yangtze.

Key words: TRMM, GMS, Huaihe River Basin, land temperature, split window, NDVI
