AST_05 V003

10.5067/ASTER/AST_05.003
ASTER Surface Emissivity
AST_05

The ASTER Surface Emissivity (AST_05) is an on-demand product 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.
