Thanks for starting this! One thing to note while WACCM is HT we would stick with FWHIST rather than FHTHIST.

I think that would work but not sure how FX fits in... @fvitt should comment. I think the idea here is to avoid keying off the number of levels to...

@cacraigucar -- @fvitt is certainly the expert for this, but I think it should be as simple as copying the directory src/chemistry/pp_waccm_sc_mam4 to src/chemistry/pp_ghg_mam4 and adding CO2 to the chem_mech.in...

@adamrher what are the current atm_in settings used in the FHIST compset for the section &chem_surfvals_nl I hope it's a simple as adding 'CO2' to the flbc_list and pulling from...
