NASA ASTER GED Project

The AG1kmB Version 3 dataset was decommissioned as of December 14, 2016. Users are encouraged to use the ASTER Global Emissivity Dataset 1-kilometer AG1km dataset in HDF5. The Terra Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Emissivity Dataset (GED) land surface temperature and emissivity (LST&E) data products are generated using the ASTER Temperature Emissivity Separation (TES) algorithm with a Water Vapor Scaling (WVS) atmospheric correction method using Moderate Resolution Imaging Spectroradiometer (MODIS) MOD07 atmospheric profiles and the MODerate sp...AG1kmB Version 3数据集已于2016年12月14日正式停用。推荐用户采用HDF5格式存储的ASTER全球发射率数据集1公里分辨率AG1km数据集。Terra高级星载热发射与反射辐射计（Advanced Spaceborne Thermal Emission and Reflection Radiometer, ASTER）全球发射率数据集（Global Emissivity Dataset, GED）的地表温度与发射率（Land Surface Temperature and Emissivity, LST&E）数据产品，采用ASTER温度发射率分离（ASTER Temperature Emissivity Separation, TES）算法，并结合基于中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer, MODIS）MOD07大气廓线的水蒸气定标（Water Vapor Scaling, WVS）大气校正方法，以及MODerate sp...
