Is this behaviour not what the "condensibles" argument to atm_fields_compactAddConstant already does? That was my understanding from reading the documentation! I'm quite happy with the definition of VMR as it is, having just spent ages trying to get my head around what the "correct" VMRs for O2 and N2 are to pass to the legacy complete absorption models in order to reproduce the expected absorption, since lots of these models seem to have a default assumption about what the VMR is built in to the line-strength constants.
