Welcome to the Earthdata Forum! Here, the scientific user community and subject matter experts from NASA Distributed Active Archive Centers (DAACs), and other contributors, discuss research needs, data, and data applications.
All ASTER data, aside from the Precision Terrain Corrected (AST_L1T) and expedited data (AST_L1AE and AST_L1BE), require an order to be placed, as the product will be made on-demand. This includes radiance data (AST_09, AST_09T, AST_09XT, AST_L1B, and AST_14OTH), elevation data (AST14DEM, AST14DMO), emissivity data (AST_05), temperature data (AST_08), reflectance data (AST_07 and AST_07XT), and unprocessed data (AST_L1A). In addition, ASTER GDEM (ASTGTM) Version 3 data can be accessed using NASA's Earthdata Search.
