基于RS的陆面温度反演研究进展

Research on the Retrieving of Land Surface Temperature Based on RS

陆面温度(LST)是研究地表和大气之间物质交换和能量交换的重要参数,利用遥感方法反演陆面温度已经成为重要的获取陆面温度的途径.回顾了热红外遥感研究,阐述了地表温度反演原理,比较了2种主要的地表温度反演方法,并重点对针对Landsat TM数据的3种温度反演算法进行了对比.利用遥感研究地表温度将向着精确化的方向发展,如何利用反演出的精确地表温度将是更加重要的工作.

Land surface temperature （LST） is a more important parameter in studying the material exchange and energy exchange between the land and the atmosphere. Retrieving of the land surface temperature by remote senseing （RS） has been an important method in obtaining the land surface temperature. This paper reviews the research of the hot infrared remote sensing, explains the principle of the retrieving of land surface temperature, compares two main methods of the retrieving of the land surface temperature, and contrasts the three different temperatures based on the Landsat TM data especially. Researching land surface temperature by remote senseing will develop in the accurate direction, and how to utilize the obtained accurate land surface temperature will be more important.
