Google Earth Engine ——高级星载热辐射和反射辐射计全球发射率数据库(ASTER-GED)地表温度数据集
The Advanced Spaceborne Thermal Emission and Reflection Radiometer Global Emissivity Database (ASTER-GED) was developed by the National Aeronautics and Space Administration's (NASA) Jet Propulsion Laboratory (JPL), California Institute of Technology. This product includes the mean emissivity and standard deviation for all 5 ASTER Thermal Infrared bands, mean land surface temperature (LST) and standard deviation, a re-sampled ASTER GDEM, land-water mask, mean Normalized Difference Vegetation Index (NDVI) and standard deviation, and observation count.
ASTER-GED land surface temperature and emissivity (LST&E) are generated using the ASTER Temperature Emissivity Separation (TES) algorithm in combination with a Water Vapor Scaling (WVS) atmospheric correction method using MODIS MOD07 atmospheric profiles and the MODTRAN 5.2 radiative transfer model.
This product was derived from clear-sky pixels for all available ASTER data (2000-2008).

高级星载热辐射和反射辐射计全球发射率数据库(ASTER-GED)是由美国国家航空航天局(NASA)加州理工学院喷气推进实验室(JPL)开发。该产品包括所有5个ASTER热红外波段的平均发射率和标准差,平均陆地表面温度(LST)和标准差,重新采样的ASTER GDEM,陆地-水掩码,平均归一化植被指数(NDVI)和标准差,以及观测次数。
ASTER-GED地表温度和发射率(LST&E)是使用ASTER温度发射率分离(TES)算法,结合水汽缩放(WVS)大气校正方法,使用MODIS MOD07大气剖面和MODTRAN 5.2辐射传输模型生成。
这个产品是由所有可用的ASTER数据(2000-2008)的晴空像素得出的。
