[CF-metadata] standard name proposal for CCMVal

Dear Jonathan and Martin,

I don't normally wade in muddy waters, but perhaps a separate
perspective would be useful. Problem is that I'm hopelessly uneducated
in this area.

I always thought that "burden" referred to some amount (either moles per
unit area or mass per unit area) of a chemical species in the *entire
atmospheric column*, extending from the surface to the top of the
atmosphere. Is this correct?

If it is invariably the total column amount, then I think
atmosphere_mole_burden_of_X is a more specific definition than
moles_of_X_in_atmosphere, which I should think could refer to moles per
unit area or moles per unit volume, or even total number of moles in
some limited region of the atmosphere. Of course the units attribute
should make this clear.

If, on the other hand, atmosphere_mole_burden_of_X is more general than
total column amount per unit area, then I think moles_of_X_in_atmosphere
is better because it is plainer English.

Forgive me, if you've already gone over this ground before.

cheers,
Karl
