404 Not Found for Granule Metadata File MOD13A2

by africanriskcapacity » Fri Mar 24, 2023 6:11 am America/New_York

Hi there,

Until recently I have been able to discover (through CMR) and download the MODIS MOD13A2 product (C6.1), including metadata -- from which we read the hash to validate the downloaded .hdf file.

However, now the LP DAAC gives HTTP 404 resource not found for .hdf.xml file; for example:

Available:
https://data.lpdaac.earthdatacloud.nasa.gov/lp-prod-protected/MOD13A2.061/MOD13A2.A2023049.h17v05.061.2023070134018/MOD13A2.A2023049.h17v05.061.2023070134018.hdf

NOT available:
https://data.lpdaac.earthdatacloud.nasa.gov/lp-prod-protected/MOD13A2.061/MOD13A2.A2023049.h17v05.061.2023070134018/MOD13A2.A2023049.h17v05.061.2023070134018.hdf.xml

For your reference, in some alternative download location the .hdf.xml is actually available:
https://e4ftl01.cr.usgs.gov/MOLT/MOD13A2.061/2023.02.18/


Could you look into the issue? Hope this can be resolved soon.

Thanks,
Rob

@africanriskcapacity ,

Thanks for point this out. As you probably know, the LP DAAC is migrating its on-prem data to the Earthdata Cloud. With this comes a few changes, which you stumbled upon, and we apologized for the inconvenience. The .hdf.xml file you know from the on-prem data distribution system has been replaced by the .cmr.xml file for data that’s been migrated to the cloud. Unfortunately, that’s not the only change here. While the .cmr.xml contains the same metadata information – including the checksums – as the .hdf.xml file, the structure and the keywords are slightly different so any scripts that parse the xml file will need to be updated to the schema used by the .cmr.xml file. Again, we apologize for the inconvenience. Please reach out if you have any further questions.
