As of 1 April 2016, all Advanced Spaceborne Thermal Emission Reflection Radiometer (ASTER) data products are available at no charge from LP DAAC.
On April 1, 2016, NASA’s Land Processes Distributed Active Archive Center (LP DAAC) began distributing Advanced Spaceborne Thermal Emission and Reflection (ASTER) Level 1 Precision Terrain Corrected Registered At-Sensor Radiance (AST_L1T) data products over the entire globe at no charge. The AST_L1T product provides a quick turn-around of consistent GIS-ready data as a multi-file product, which includes a HDF-EOS data file, full-resolution composite images (FRI) as GeoTIFFs for tasked telescopes (e.g., VNIR/SWIR and TIR), and associated metadata files. In addition, each AST_L1T granule contains related products including low-resolution browse, and when applicable, a quality assurance (QA) browse and QA text report.
More than 2.95 million scenes of archived Terra ASTER data are now available for direct download through the LP DAAC Data Pool and for search and download through NASA’s Earthdata Search. New scenes will be added as they are acquired and archived.
