cesm2_init is the default value for RUN_REFDIR. So I don't believe there is a need have those entries for RUN_REFDIR which are all set to cesm2_init.

@lkemmons should be able to provide advice on how MEGAN emissions should be implemented

> @billsacks and @adrifoster this is the thing that gets in the way of the Ozone tag. What is the "Ozone tag"?

> I think there's more than just that: It looks like we also need to stop setting drydep_method in drv_flds_in, possibly replacing it with some new variable. @fvitt can you...

@lkemmons @dlawrenncar In what units should the lightning flash frequency passed to the mediator be? It seems that mo_lightning computes the flash frequency in units of /min. I can easily...

@ekluzek How does this sound for a namelist indicator in drv_flds_in? ``` char drv_flds_in lightning_coupling_nl If TRUE atmosphere model will provide prognosed lightning flash frequency ```

I am not sure if we are estimating cloud-to-ground flash freq or just the total flash frequency. @lkemmons do you know? https://github.com/ESCOMP/CAM/blob/cam_development/src/chemistry/mozart/mo_lightning.F90

I believe this will give cloud-to-ground flash frequency (per minute) in each grid box which CAM will pass to the mediator (to CTSM) ``` cam_out(c)%lightning_flash_freq(i) = flash_freq(i,c)*cgic(i,c) ``` @ekluzek Is...

@dmleung I don't know which soil erod files should be moved to CTSM. @lkemmons and @tilmes may have an opinion on this.
