I'm still shooting for sometime this calendar year, but I never make promises about these things - they usually turn into lies....
I am a bit confused about concept ids. For MODIS L3 mapped data for CHL, FLH, POC, RRS, and SST I have this:
However, the names for the second and third datasets in these lists don't quite match. C1458097483-OB_DAAC is "Terra Moderate Resolution Imaging Spectroradiometer (MODIS) Fluorescence Line Height (FLH) Global Mapped Data, reprocessing v2018", while C1442922863-OB_DAAC is "Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) Fluorescence Line Height (FLH) Global Mapped Data" - no "reprocessing". Did I get any of them wrong?
Concept IDs are Earthdata Search's way of keeping track of datasets so we don't have control over those. The good news is that what you have found is correct. The text you mentioned is "free text", so that may change slightly from one reprocessing to another. The best way to verify the version is by looking for the version tag/attribute for the product. You can see it displayed in gray on the bottom of the product description in Earthdata Search. https://search.earthdata.nasa.gov/search?q=C1442922863-OB_DAAC
To find the products by the name we assign at OBPG, use the name shown in gray before version: "MODISA_L3m_FLH". Then you will find any product by that name, any version that exists.
which returns https://oceandata.sci.gsfc.nasa.gov/cmr/getfile/T2020122.L3m_DAY_CHL_chl_ocx_4km.nc
which returns nothing
If you. want more current data, you'll need to look at the corresponding NRT collections.
In this particular case (MODIS-Terra chlorophyll):
C1458097478-OB_DAAC = MODIST_L3m_CHL
C1458149042-OB_DAAC = MODIST_L3m_CHL_NRT
