AG100: ASTER Global Emissivity Dataset 100-meter V003

  • The ASTER Global Emissivity Database (ASTER-GED) provides land surface temperature and emissivity data derived from ASTER satellite imagery.

  • It includes mean and standard deviation for emissivity in 5 thermal infrared bands, land surface temperature, NDVI, and elevation.

  • Covering the period from 2000 to 2008, the dataset was developed by NASA JPL and is available at a 100-meter resolution.

  • ASTER-GED data and products (excluding ASTER GDEM v2) have no restrictions on use, sale, or redistribution.

  • Users can explore and analyze the ASTER-GED dataset using Google Earth Engine.

Description

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).
