The PO.DAAC would like to inform its users about the PO.DAAC Cloud Data Migration Timeline Update.
- The Phase 3 and 4 of our migration will be transitioned on November 14th, 2022.
- The retirement date for PO.DAAC Drive and certain legacy data access tools and services (specifically LAS, CWS, THREDDS) will be moving to March 31, 2023. After March 31, 2023, users will only be able to access PO.DAAC data through the NASA Earthdata Cloud endpoints.
As detailed in the 12 July 2021 announcement, PO.DAAC has been migrating datasets to the NASA Earthdata Cloud, hosted in Amazon Web Services (AWS). PO.DAAC data have been migrated to the cloud in four phases.
For up-to-date information, please visit the PO.DAAC Cloud Data Migration page and subscribe to the PO.DAAC mailing list.
What Users Can Expect on November 14, 2022:
- Discoverability of the local archive instance of Phase 3 and 4 datasets will be removed and only the cloud archive version will be available.
- References to legacy data access tools and services for the Phase 3 and 4 datasets, including PO.DAAC Drive, will also be removed.
- The PO.DAAC users will need to complete the transition of their legacy data access scripts and methods to conform to cloud data access endpoints, as PO.DAAC Drive and certain legacy data access tools and services (LAS, CWS, THREDDS) will be retired in the near future.
- Earthdata Cloud access end-points for the listed datasets can be found on the respective dataset landing pages under Data Access tab:
- CMR Virtual Directories provides HTTPS endpoint for data browse and download;
- Earthdata Search provides search and data access or download capabilities, for both in-cloud and non-cloud workflows.
- An additional CLOUD DATASETS listing page for cloud enabled datasets is available on the PO.DAAC Web Portal, which offers more tool/service integration
- The Earthdata Cloud data access end-points are also made available on this listing.
- Users will need to create a free Earthdata Login Account in order to download files or access PO.DAAC data through the Earthdata Cloud.
