Thanks Jonathan,
Yes, OK.
I guessed why you wanted the vaguer term!
Cheers, Roy.

Subject: [CF-metadata] new standard name request for pH
Dear Roy
Thanks for clarification.
> pH_of_sea_water_defined_by_mole_concentration_of_hydrogen_ion_per_unit_mass (free scale)
> pH_of_sea_water_defined_by_mole_concentration_of_hydrogen_ion_per_unit_volume (NBS)
In other standard names, "mole concentration" means mol m-3. So the second
should be
> pH_of_sea_water_defined_by_mole_concentration_of_hydrogen_ion (NBS)
In existing names, we say "moles per unit mass" for mol kg-1. So the first is
> pH_of_sea_water_defined_by_moles_of_hydrogen_ion_per_unit_mass (free scale)
OK?
My main argument for plain pH_of_sea_water is that in many ocean models these
two quantities would be identical.
Cheers
Jonathan
