Thanks for that interesting discovery! mole metres-2 does not have the same
physical dimensions as metres, so it must be given a different standard name.
At present we have many atmosphere_mass_content names in kg m-2, and many
tendency_of_ocean_mole_content names in mol m-2 s-1, so I'd suggest the
consistent name for this quantity would be atmosphere_mole_content_of_ozone
in mol m-2, and DU would be dimensionally equivalent to that.
