ASTER L1A Reconstructed Unprocessed Instrument Data

by persia » Thu Jan 22, 2026 9:57 pm America/New_York

When I was downloading the ASTER L1A Reconstructed Unprocessed Instrument Data, I found that there were only files in HDR format in Earthdata. Could I still download the ZIP format files (which are in Geotif format)?

@persia Thank you for your message regarding the availability of a GeoTIFF output option for ASTER Version 4. As ASTER products are now archived, we are only storing the HDF versions of the ASTER L1A and L1B products going forward.

Please send an email to LP DAAC User Services

please see this news announcement about the release of ASTER Version 4 data: https://www.earthdata.nasa.gov/data/alerts-outages/aster-version-4-historical-processing-completed

Thank you very much for your response.I would like to ask if there is any method to convert HDR format data into the previous GeoTIFF data?
Looking forward to your reply.
