    Output BVOC species mixing ratios in CAM6

    Hi all, I'm a CESM2 novice interested in BVOC emissions. I'm planning some runs using a CESM2 build that couples CLM5 and CAM6. I know that the MEGAN model in CLM5 produces various BVOC species and that CAM6 can be set to show the MEGAN fluxes from the land to the atmosphere by adding the...

    how to close atmospheric chemistry in FHIST_BGC case

    Hi 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...

    How to add heterogeneous reaction in CAM-chem

    Dear all, 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.
