Hi Alison, Christophe, et al.,
I agree that this name follows existing patterns.
It would be good to add a comment similar to the one we added for
atmosphere_mole_content_of_ozone (although we don't currently have the
corresponding layer version of
equivalent_thickness_at_stp_of_atmosphere_ozone_content, so the wording will
need to be tweaked):
"N.B. Data variables containing column content of ozone can be given the
standard name of either equivalent_thickness_at_stp_of_atmosphere_ozone_content
or atmosphere_mole_content_of_ozone.The latter name is recommended for
consistency with mole content names for chemical species other than ozone."
Although this shouldn't affect the current proposal, I note for the record that
it seems strange that for the Integral of the whole atmosphere our pattern is:
atmosphere_X_content
But for a partial integral we put 'atmosphere' after X:
X_content_of_atmosphere_layer
Best wishes,
Philip
