基于Landsat-5 TM估算地表温度

Estimating Land Surface Temperature from Landsat-5 TM

基于Landsat-5 TM的热红外波段(6波段)数据,运用覃志豪的单窗算法估算了张掖绿洲地区的地表温度,结果表明沙漠和戈壁的地表温度最高,水体和绿洲的温度最低,估算的地表温度的结果符合地表水热关系。因此,这种方法能较好地反演出张掖绿洲地表温度的分布状况。

In this paper, we used the thermal infrared band of Landsat-5 TM to estimate Land Surface Temperature （LST） with Qin＇s mono-window algorithm. These results show surface temperature of water body and oasis are low; and desert and gobi are high. These results are consistent with the relation of hydro-thermal. So this mono - window algorithm can be used to estimate spatial distribution of land surface temperature over Zhangye oasis.
