I am planing a long time (more than 200 years) run for FHIST_BGC case, and I find the atm takes more than 80 percent of the total run time. So, I would like to close the atmospheric chemistry to reduce run cost.
I attempt to only change the CAM_CONFIG_OPTS from "-phys cam6" to "-phys cam6...
I'm running CAM-chem simulation with CESM2.1.0 and I want to add heterogeneous reactions in the FCHIST compset.
Where should I change the chemical mechanism?
Which file should I add the reactions and individualized reaction rate constant?
I really appreciate your helps.
