Re: revision_date vs 'updated' in CMR granule search?

by the CMR itself, to describe the metadata record - therefore it will always move forward in time. To iteratively query for updates you can safely move your start-time forward to your previous end-time. The production date, on the other hand, is set by the provider as product metadata describing th...

Re: revision_date vs 'updated' in CMR granule search?

Followup question: I plan to use either production or revision dates as a temporal filter to make sure I retrieve all records from the CMR.

Re: revision_date vs 'updated' in CMR granule search?

Some followup questions:

1. What is the difference between concept_id and collection_concept_id and why is the latter more appropriate?

2. Is there a limit on the number of parallel CMR queries we can send you? We can sometimes generate hundreds of simultaneous queries unless I add some throttling.

Re: revision_date vs 'updated' in CMR granule search?

In order to search for granules in a range of ProductionDate values, use the production_date parameter. See: https://cmr.earthdata.nasa.gov/search/site/docs/search/api.html#g-production-date E.g., to search for granules in your target collection with production_date in the range since 2020-10-16T20:...
