Issues Accessing the Ocean Color ATBD Documentation

Since EarthData has now consolidated most of the previous data websites, I’d like to ask whether some of the older documents are still accessible. I’m unable to find a significant portion of the ATBD documentation that was previously available on the Ocean Color website on the consolidated EarthData pages. For example, the page that used to be at https://oceancolor.gsfc.nasa.gov/atbd/ocl2flags/.
Best wishes.

One place to find ATBDs is on the OB.DAAC Center page under OBPG Product Suite descriptions: https://www.earthdata.nasa.gov/centers/ob-daac/data-access-tools

Another place for ATBDs is on each dataset landing page on the Earthdata website: https://www.earthdata.nasa.gov/data/catalog/ob-cloud-pace-oci-l2-bgc-3.2#documents-and-resources

You can find dataset landing pages from the Earthdata Data Catalog: https://www.earthdata.nasa.gov/data/catalog

Let me see if I can find an answer on those L2 flags...

Same issue from here: cannot find any more the MODIS ATBDs, for instance. The 3 links you provide in your answer do not do that actually. A bit lost now! Would be awesome if you could make this easier to find. Thanks!
