ASTER Global Emissivity Dataset, Monthly, 0.05 deg, netCDF4

Published by LP DAAC;NASA/JPL/ASTER | National Aeronautics and Space Administration | Metadata Last Checked: September 14, 2025 | Last Modified: 2025-09-10
The AG5KMMOH Version 4 dataset was decommissioned as of December 14, 2016. Users are encouraged to use [Version 4.1 of ASTER Global Emissivity Dataset, Monthly, 0.05 degree, HDF5](https://doi.org/10.5067/Community/ASTER_GED/AG5KMMOH.041).The Terra Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Emissivity Dataset (GED) is a collection of monthly files (see known issues for gaps) for each year of global emissivity. The ASTER GED data products are generated for 2000 through 2015 using the ASTER Temperature Emissivity Separation (TES) algorithm atmospheric correction method. This algorithm method uses Moderate Resolution Imaging Spectroradiometer (MODIS) Atmospheric Profiles product [MOD07](https://doi.org/10.5067/MODIS/MOD07_L2.006) and the MODerate spectral resolution TRANsmittance (MODTRAN) 5.2 radiative transfer model along with the snow cover data from the standard monthly MODIS/Terra snow cover monthly global 0.05 degree product [MOD10CM](https://doi.org/10.5067/MODIS/MOD10CM.006), and vegetation information from the MODIS monthly gridded Normalized Difference Vegetation Index (NDVI) product [MOD13C2](https://doi.org/10.5067/MODIS/MOD13C2.006).The National Aeronautics and Space Administration’s (NASA) Jet Propulsion Laboratory (JPL), California Institute of Technology, developed the ASTER GED product.Improvements/Changes from Previous Versions* This V4 product incorporates an emissivity adjustment to the ASTER GED V003 product. See “[The ASTER Global Emissivity Dataset (ASTER GED): Mapping Earth’s emissivity at 100 meter spatial scale](https://doi.org/10.1002/2015GL065564)" publication Section 4 for more information.
