ASTER Global Emissivity Dataset, 100 meter, HDF5 V003

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_L2 atmospheric profiles and the MODerate spectral resolution TRANsmittance (MODTRAN 5.2 radiative transfer model). This dataset is computed from all clear-sky pixels of ASTER scenes acquired from 2000 through 2008. AG100 data are available globally at spatial resolution of 100 meters.

The National Aeronautics and Space Administration’s (NASA) Jet Propulsion Laboratory (JPL), California Institute of Technology, developed the ASTER GED product.

高级星载热发射和反射辐射计（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，结合基于中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer，MODIS）MOD07_L2大气廓线的水汽缩放（Water Vapor Scaling，WVS）大气校正方法，以及中分辨率光谱透射辐射传输模型（MODTRAN 5.2）生成。本数据集基于2000年至2008年获取的所有ASTER影像晴空像素计算得到。其中AG100数据以100米空间分辨率实现全球覆盖。

ASTER GED产品由美国国家航空航天局（National Aeronautics and Space Administration，NASA）下属加州理工学院的喷气推进实验室（Jet Propulsion Laboratory，JPL）研发。
