AST_05 v003

ASTER Surface Emissivity


PI: U.S./Japan ASTER Science Team

Description

The 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. The product is comprised of per-pixel emissivity measurements generated over land in addition to embedded metadata and quality assurance data planes.
