Dear Christophe,
Thank you for proposing this name. I think mole_content_of_ozone_in_atmosphere_layer is the correct name and it is consistent with existing names such as mass_content_of_water_in_atmosphere_layer. The canonical units would be mol m-2 as for the total column name. Regarding your suggested definition, I think we could delete the third sentence: "mole_content_of_X_in_atmosphere_layer" means the vertically integrated number of moles of X above a unit area" as it is essentially repeating the information contained in the previous two sentences, but otherwise it looks fine.
Best wishes,
Alison
