During 2021 PO.DAAC is in the process of migrating its data archive to the Earthdata Cloud, hosted in Amazon Web Services (AWS). During this transition, some data will continue to be available from the on premise archive, while some data will also be available from and within the Earthdata Cloud.

What to Expect

You will notice there will be some duplicate collections available. For example, if you search for “VIIRS_N20-OSPO-L2P-v2.61” in Earthdata Search, you will see two collections. One of these is our normal, on-premise collection, while the other is the cloud hosted collection.

The PO.DAAC Web Portal will label cloud hosted datasets as  CLOUD ENABLED  in an orange rectangle. This will let you know, at a glance, which datasets are cloud-enabled from the dataset search and dataset landing pages. For now, check out the Migration FAQ “How do I know if a collection is in the cloud or not? below.

In the future, we will be removing discoverability of the “on-premise” collection and only the cloud version will be available, and you will not see duplicates.

Migration FAQs
Are there any collections in the cloud I can try out right now?

Public cloud collections are those that are new to PO.DAAC and went immediately into the cloud. These collections are only available through the cloud. Some examples of these are the ECCO data products. As new collections become available, you will see them show up on our Portal, CMR, and Earthdata Search. You will soon also see migrated datasets from PO.DAAC on-premise into the cloud and both will be available until on-premise access ends.

How do I know if a collection is in the cloud or not?

There are several ways to see the PO.DAAC cloud collections.

For public collections, you can use Earthdata Search and the PO.DAAC Web portal filter options.

The PO.DAAC Web Portal will also label datasets as  CLOUD ENABLED  in an orange rectangle. This will let you know, at a glance, which datasets are cloud-enabled from the dataset search and dataset landing pages.

On Earthdata Search, you can use the ‘Available from AWS Cloud’ feature, as well as searching using the key word  POCLOUD.  But for PO.DAAC Cloud collections only, we’ve built a PO.DAAC Cloud Search Portal (again, make sure you’re logged in!).

Why are there so few collections in the first phase? Why so many in other phases?

The first set of collections moving to the cloud were scoped to the most used or voluminous PO.DAAC collections*. PO.DAAC wanted to make these collections available in the cloud to our user community as soon as possible to educate and foster the migration process. Once a user understands the cloud access points, migrating to new collections will be done consistently and easily.

Because access will be consistent, PO.DAAC feels confident in migrating more and more collections over the last 3 phases.

*These collections account for nearly 75% of PO.DAAC data volume, 80% of our distribution, and 40% of our total number of files.
