Summary: Introduce refactored ZM modifications from THT Contributors: Thomas Toniazzo (@tto061) with editing assistance from @oyvindseland and @gold2718 Reviewers: @oyvindseland Purpose of changes: Improving energy conservation and re-introducing specific NorESM2 ZM settings into NorESM3 (ESCOMP#225) Github PR URL: NorESMhub#235 Changes made to build system: None Changes made to the namelist: - `zmconv_tiedke_lnd`: Parcel temperature perturbation over land in ZM deep convection scheme in units of (K). - Default: a 1K perturbation - `zmconv_use_moist_plume_thermo`: Account for freezing in plume-ensemble buoyancy. When `.true.`, use moist thermodynamics to compute plume-ensemble properties. - Default: `.false.` - `zmconv_retrigger`: Iterate plume-ensemble computation and trigger functions. - Default: `.false.` - `zmconv_entrmn`: Maximum entrainment rate for plume ensemble - Default: 2e-4 m-1 - `zmconv_alfadet`: Convective detrainment/entrainment ratio - Default: 0.1 - `zmconv_plclmin`: Minimum LCL pressure to allow ZM deep convection - Default: 600 hPa - `compute_enthalpy_flux`: Enthalpy flux terms explicitly computed and added in the atmosphere and passed to an active ocean component. - Default: `.false.` Changes to the defaults for the boundary datasets: None Substantial timing or memory changes: None - Added `compute_enthalpy_flux to air_composition` namelist variable but not the code to calculate or send the enthalpy. - Added a regression test of the ZM mods that sets `zmconv_retrigger` and `zmconv_use_moist_plume_thermo` to `.true.` and turned on all ZM output fields. Verified that this test is BFB when `zmconv_retrigger` and `zmconv_use_moist_plume_thermo` are `.false.`. - aux_cam_noresm: Most tests pass except for namelist differences caused by the new namelist items (see above). - ERP_Ln9.ne16pg3_ne16pg3_mtn14.NF1850ghg_fates-nocomp.betzy_intel.cam-outfrq9s is an expected fail due to a CLM restart failure. - NorESMhub#225
