ASTER is an instrument on the Terra satellite. ASTER Global Emissivity Dataset (GED) is a global, 90-meter spatial resolution emissivity map of the Earth’s non-frozen land surfaces at different wavelengths in the thermal infrared spectrum. ASTER GED bands 13, 14, and Normalized Difference Vegetation Index (NDVI) are used in the surface temperature algorithm for Landsat 4-9 data.

Back to Products Overview

These data are available for users wanting to generate custom Level-2 products using the Collection 2 surface reflectance and surface temperature algorithms. **It is not necessary for users to download the atmospheric auxiliary data for use with Collection 2 Level-2 products. **

Emissivity data from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Emissivity Dataset (GED) bands 13, 14, and Normalized Difference Vegetation Index (NDVI) are used in the ST algorithm for Landsat 4-9 data. The ASTER GED is divided into a separate file for each 1×1-degree area of all major non-frozen land masses of the Earth’s land surface. Antarctica and some small islands are not covered. The USGS extracts Emissivity, NDVI, and geolocation information from each ASTER GED file and stores them in a new Hierarchical Data Format Version 5 (HDF5) file. Within a file, the Emissivity and NDVI data are recorded in 100m grids. The Emissivity “Mean” and “SDev” datasets contain a value for ASTER bands 10, 11, 12, 13, and 14, although only bands 13 and 14 are used in the ST algorithm. The latitude and longitude values at each grid point are also stored. The new files are in the same format and spatial resolution as the original files.
