| 摘 要： | 利用MODIS数据可见光波段b1、近红外波段b2和中红外波段b19，获得所需要的两个基本参数：地表比辐射率和大气水分含量，然后对于热红外波段b31，采用Jimenez—Mufioz和Sobrino的普适性单通道算法反演地表温度。最后以长株谭地区为研究区，研究结果表明，这一方法能获得较为合理的地表温度。

| Abstract: | First of all,the surface emissivity was computed from the band 1 and band 2 of MODIS data,and the atmospheric water content was computed from the band 2 and band 19.Then in conjunction with the band 31,the values of land surface temperature were derived by a generalized single-channel method developed by Jim nez-Mu oz and Sobrino.At last,this method was applied to Chang-Zhu-Tan area and the result shows that the method can yield a reasonable estimation of land surface temperature. |
