AG100: ASTER Global Emissivity Dataset 100-meter V003 (NASA/ASTER_GED/AG100_003)

Version V003

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
