MODIS AQUA CMR concept ID
Posted: Tue Apr 15, 2025 3:34 am America/New_York
Can you provide MODIS AQUA CMR concept ID for CHL, KD, PAR, Rs Level 3 Data?
Hello. Concept IDs change as versions change, so be careful to check for the latest available version.
Here is an example of how to find collection concept IDs using a CMR query. Search for the field "concept-id" and find the one that begins with the letter 'C'. Collection concept-id's start with the letter 'C'.

If you are not sure about a collection short_name, you can find the collection in Earthdata Search first. By the way, the Earthdata Search URL will show the collection concept ID too!

In both examples, you'll see the concept id for Aqua MODIS L3 mapped chlorophyll is C3380709133-OB_CLOUD.
