…x for bulk aerosols (BAM) (#331) Originator(s): @jimmielin Most of the code based off from @fvitt; changes had to be made to remove use of pbuf and use the constituents infrastructure in CAM-SIMA/CCPP framework to register store prescribed aerosols data (code borrowed from @peverwhee and @nusbaume) Companion SIMA PR ESCOMP/CAM-SIMA#441 There will not be a CAM PR to bring these changes back because `tracer_data` has breaking interface changes (and no longer using pbuf) that make it infeasible to bring back these schemes into CAM. Description (include issue title and the keyword ['closes', 'fixes', 'resolves'] and issue number): - CCPPize CAM `prescribed_ozone` -- closes #323 - CCPPize CAM `prescribed_aero` into `prescribed_aerosols` scheme -- closes #328 - Partially CCPPize CAM `aerodep_flx` into `prescribed_aerosol_deposition_flux` scheme: only BAM functionality is fully implemented; MAM functionality depends on conversion of the aerosol model -- closes #328; future work documented in #329 List all namelist files that were added or changed: ``` A schemes/chemistry/prescribed_ozone_namelist.xml A schemes/chemistry/prescribed_aerosols_namelist.xml A schemes/chemistry/prescribed_aerosol_deposition_flux_namelist.xml ``` List all files eliminated and why: N/A List all files added and what they do: ``` A schemes/chemistry/prescribed_ozone.F90 A schemes/chemistry/prescribed_ozone.meta - complete CCPPization of prescribed_ozone (#323) A schemes/chemistry/prescribed_aerosols.F90 A schemes/chemistry/prescribed_aerosols.meta - complete CCPPization of prescribed_aero (#328) A schemes/chemistry/prescribed_aerosol_deposition_flux.F90 A schemes/chemistry/prescribed_aerosol_deposition_flux.meta - CCPPize aerodep_flx for bulk aerosols (BAM) only. (#328) future work #329 A test/test_suites/suite_tracer_data_test.xml - suite for testing tracer_data chemistry and aerosols input test via prescribed ozone, aerosols, and aerosol deposition flux -- BAM configuration ``` List all existing files that have been modified, and describe the changes: (Helpful git command: `git diff --name-status development...<your_branch_name>`) N/A List all automated tests that failed, as well as an explanation for why they weren't fixed: N/A Is this an answer-changing PR? If so, is it a new physics package, algorithm change, tuning change, etc? new chemistry and aerosol schemes If yes to the above question, describe how this code was validated with the new/modified features: new regression test verified b4b with cam using same namelist options and input files as described in testmod - see CAM-SIMA PR --------- Co-authored-by: Jesse Nusbaumer <nusbaume@ucar.edu>
