Hi Tyler,
> Regarding the measurement keywords, the EOSDIS data centers needed a more fine-grained list of specific measurements (e.g.atmosphere_absorption_optical_thickness_due_to_black_carbon_ambient_aerosol_at_532nm) than the science keywords offered.
It appears to me that the correct place for this is in the CF Conventions... which has a hugely active community for exactly this kind of thing. Actually, if you look at the current CFConventions standard name table, you can already find atmosphere_absorption_optical_thickness_due_to_black_carbon_ambient_aerosol... try it out http://cfconventions.org/Data/cf-standard-names/70/build/cf-standard-nam...

This is even more concerning... why wasn't guidance issued to use CFConventions?

... there are thousands of existing, well defined variables measured in CFConventions. Why start a new list in GCMD?
here in that review. The measurement keywords specifically support the NASA UMM Variables Model (UMM-Var) evolution which has a field called 'MeasurementName' that allows metadata curators to provide community sourced names to further describe variable
data.
I understand that other variable names can be used in UMM, namely CFConventions. Thanks for pointing that out.
