Standard for surface level prefix/suffix?

[svahl991]

I think we've discussed this before, but I didn't find an official issue. Apologies if I missed it.

I believe the ESM standard is to use the suffix _at_surface for surface variables, which departs from CF naming, which often uses a surface_ prefix. But some ESM names still seem to carry the CF name. For example, air_pressure_at_surface is listed right above surface_pressure_of_dry_air:

ESMStandardNames/Metadata-standard-names.md

Lines 114 to 116 in 71d9a92

	* `air_pressure_at_surface`: Air pressure at local surface
	* `real(kind=kind_phys)`: units = Pa
	* `surface_pressure_of_dry_air`: Surface pressure of dry air

Is the plan to do a "bug smash' sometime to bring ESM into consistency on this? Is there a timeline for this effort? Or is this likely to be the case for a while? For new names being added, the plan is to enforce the _at_surface suffix?

Thanks.
