[CF-metadata] Proposal for additional CF biogeochemistry attributes

Hi,

I was too quick in my last msg, sorry. Got to thinking about the n/p ratio and checked it out with the people who programmed it. It is the ratio of mole concentrations that we are calculating and putting into netCDF files. That's what we suggest establishing a standard_name for.

Our motivation is that marine biologists use the N/P ratio, calculated in this way. (They also seem to prefer expressing oxygen concentration in ml/l, by the way.)

Should we change the proposed name to "mole_ratio_of_nitrate_to_phosphate_in_sea_water"?

Cheers,
Bruce
