… atmos_phys This is the first step to CCPP conversion of MAM. This PR completes the CAM side work. It refactors CAM-specific code into CAM interfaces (_cam suffix) and includes the MAM core science code sourced from the atmos_phys external. Refactor into portable code: modal_aero_calcsize, wateruptake, gasaerexch, rename Refactor into portable code: modal_aero_calcsize, wateruptake, gasaerexch Initial try at converting modal_aero_calcsize into portable code. Initial try at converting modal_aero_wateruptake into portable code. Put modal_aero_calcdry_run back in the portable subroutine and eliminate dual-path method - move to CAM interface. Cleanup; rewire modal_strat_sulfate Initial attempt for modal_aero_gasaerexch portability Build fixes. Alternate approach for modal_strat_sulfate (put in modal_aero_data) that does not need circular depends Diagnostic b4b (partial) fix; loffset build fix B4B fix for gasaerexch. B4B fixes Various cleanup; thread through rair B4B fix 3 Thread pi through calcsize_dry_run Initial attempt for modal_aero_rename portability. Follow-up cleanups to modal_aero_rename refactor. Refactor into portable code: modal_aero_newnuc (tendency-return). Refactor into portable code: modal_aero_coag (in-place vmr, dqdt diagnostic-only). Refactor into portable code: mo_setsox aqueous sulfur chemistry (setsox_sub + sox_cldaero + cldaero portable; mo_setsox_cam wrapper). Refactor into portable code: aero_activate (activate_aerosol) + wetdep split; rewire convproc call sites. Extract the Abdul-Razzak & Ghan activation kernel activate_aerosol from ndrop.F90 into portable aero_activate.F90. Split wetdep.F90 into portable science (clddiag, wetdepa_v1, wetdepa_v2) Refactor into portable code: full aero_convproc split + impaction tables to wetdep. Remove pre-existing dead code from wetdep scavenging routines (unused dummies/locals). Remove pre-existing dead code from aerosol drydep path. Refactor into portable code: aerosol drydep leaves + dust_sediment_mod. Remove aer_drydep_mod.F90: fully dead after the drydep portable split. Behavior-neutral; separate commit so CAM regression b4b can bisect it. Remove pre-existing dead code from MAM dust/seasalt emissions path. Refactor into portable code: MAM dust + seasalt emissions cores. Rename to avoid naming conflict with GEOS-Chem Remove pre-existing dead code from ndrop gas-mixing path. Refactor into portable code: ndrop (dropmixnuc) droplet activation core. Unify the calcsize/wateruptake diag path in modal_aerosol_state_mod for CAM and CAM-SIMA. Cleanup modal_aero_calcsize/wateruptake diag paths as they are moved to portable code.
