| 摘 要： | 基于MODIS数据,运用毛克彪的劈窗算法反演了具有冰雪、冻土地表类型的黑河流域2009年9月23日的地表温度。结果表明：沙漠和戈壁的温度最高,永久积雪/冰川的温度最低,能够客观地反映黑河流域9月下旬白天的气候特点。将反演结果与流域内9个气象站点的实测数据对比分析,得出反演的地面温度与实测的地面温度平均误差为0.82℃,在当前遥感反演地表温度的误差之内。因此,该算法适合大面积的地表温度快速反演。

| Abstract: | Land Surface Temperature(LST) is a key parameter in geophysics and is widely used in climatology,hydrology and ecology.Nowadays,many methods have been developed on retrieving LST using infrared bands,and have good results in many arid and humid regions of China.Based on MODIS data,this paper retrieves land surface temperature of Heihe Basin with Mao's split-window algorithm.The results show surface temperatures of desert and gobi are the highest,surface temperatures of water body and permanent snow/ice are ... |
