| 摘 要： | 分析了MODIS地表温度产品的误差来源，重点研究利用高分辨率遥感影像数据ASTER同步反演的验证方法。以2003年8月1日太湖地区为例，用ASTER数据的反演结果与同时相的MODIS地表温度产品进行比较，分别在太湖水面、无锡城区及城郊农田3个典型地表状况下选取感兴趣区域做线性拟合，取得了较好的结果，拟合的R2值可达0.966 6。

| Abstract: | As an important parameter governing energy balance over land,Land Surface Temperature(LST) plays an important role in meteorology,hydrology,ecology and some other disciplines.In this paper,the authors have analyzed the probable sources of errors in retrieving land surface temperature using MODIS data and dealt in detail with the validation method for simultaneous retrieval using relatively high resolution remote sensing data.A comparison between ASTER land surface temperature and MODIS LST products was conducted in Taihu area on August 1,2003.Linear regression of three typical areas in water surface,city ground,and outskirts of Wuxi respectively shows that the result is satisfactory for validation,with R~2 being 0.9666. |
