PO.DAAC has traditionally stored checksum files alongside data files in the archive. With the move to the Earthdata cloud, PO.DAAC will now store checksum information in granule metadata accessible through a search interface. While there is a programmatic (API-based) approach to querying for data file checksums, this tutorial will focus on the interactive approach using the Earthdata Search User Interface.
