Dear Martina
Although the discussion was difficult, we did in the end reach an agreement
to use the phrase "moles_of_X_in_atmosphere" for "burden". Please see Veronika
Eyring's posting of 7 March 2008
http://mailman.cgd.ucar.edu/pipermail/cf-metadata/2008/002049.html
and Alison's follow-up
http://mailman.cgd.ucar.edu/pipermail/cf-metadata/2008/002051.html
In the standard name table there are now quite a lot of names with this
phrase, and also with tendency_of_moles_of_X_in_atmosphere.
> column_integrated_mass_density_of_X_in_air : kg.m-2
In existing standard names, this is called "atmosphere_mass_content_of_X",
which corresponds to ...
> tendency_of_atmosphere_mass_content_of_X_due_to_respiration : kg.m-2.s-1
Should "respiration" specify heterotrophic, plant or soil? We have distinct
standard names of
heterotrophic_respiration_carbon_flux:kg m-2 s-1
plant_respiration_carbon_flux:kg m-2 s-1
soil_respiration_carbon_flux:kg m-2 s-1
or do you mean the total?
> tendency_of_mole_concentration_of_X_due_to_chemical_gross_production :
> mol.m-3.s-1
> tendency_of_mole_concentration_of_X_due_to_chemical_gross_destruction :
> mol.m-3.s-1
I think these should have "X_in_air", corresponding to existing standard names
of mole_concentration_of_X_in_sea_water.
> total_yearly_average_burden_of_X_in_atmosphere : mol
That is moles_of_X_in_atmosphere, as above. The "yearly average" is indicated
by the time-bounds and the cell_methods.
> total_yearly_averaged_atmospheric_loss_of_X : mol.s-1
What does "loss" mean? Is this the time-derivative with a negative sign, or
some specific removal processes?
> surface_area_density_of_X : m-1
How is this defined?
Best wishes
Jonathan
