ASTER L2 Surface Emissivity V004
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/aster/ast_05.004
The Terra Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Surface Emissivity (AST_05) is produced using the Temperature/Emissivity Separation (TES) algorithm for the five Thermal Infrared (TIR) 90 meter bands, acquired during the day or night.
Description
The product comprises per-pixel emissivity measurements generated over land in addition to embedded metadata and quality assurance data planes. Acquisitions for AST_05 ended on January 16, 2026, at 05:10:45 UTC, when the ASTER TIR instrument was permanently turned off due to power limitations on the Terra spacecraft.

Known Issues
* Level 2 products that are on the international date line/anti-meridian have incorrect bounding coordinates for the Universal Transverse Mercator (UTM) zone defined in the file metadata.
