Description

This PR does several things:

  1. Move the Noah MP initialization of surface fields from fv3atm (io/FV3GFS_io.F90) to CCPP from @climbfuji.
  2. Updates to Noah MP and Noah MP - radiation coupling from @HelinWei-NOAA. The changes in ccpp-physics require adding four additional variables in GFS_typedefs.F90.
  3. Revert a change in ccpp/data/GFS_typedefs.F90, made as part of the UGWP update PR (UGWP v0 v1 combined #241), that permanently disabled the old GFS v12-v15 convective gravity wave drag scheme. @SMoorthi-emc @ValeryYudin-NOAA please check, around line 4030 in the updated GFS_typedefs.F90.
  4. Cleanup work in GFS_typdefs.F90 for the recently merged RRTMGP updates: Add Interstitial%gas_concentrations%concs(:)%conc to the Interstitial%rad_reset call, remove RRTMGP variables that no longer exist from GFS_typedefs.meta, add missing active flags to RRTMGP variables in GFS_typedefs.meta

Issue(s) addressed

This finally completes step 2 of #214.

Fixes #206.

use CCPP_data,         only: ccpp_suite,          &
                                cdata => cdata_tile, &
                                CCPP_interstitial

where cdata is from ccpp-framework (ccpp_t). Is this a direct or indirect dependency? Whatever, I'll remove the one line.

I think that is implicit, fv3 dycore itself only needs ccpp_data and ccpp_static_api

Agreed, I'll make this change and address @barlage's comments to the ccpp-physics PR when it these PRs are the next to commit.

…_reset call, remove RRTMGP variables from GFS_typedefs.meta that no longer exist, add missing active flags to RRTMGP variables in GFS_typedefs.meta

@dustinswales I added the rad_reset call for the gas concentrations that was missing in the last PR, and fixed a few RRTMGP issues in GFS_typedefs.meta. Please check commit 1d9c848. Thanks!

I assume the changes in radiation_surface are applicable only to NoahMP.

I assume the changes in radiation_surface are applicable only to NoahMP.

Yes, they are only used when the ialbflg parameter is set to 2. All regression tests that do not use Noah MP pass against the existing baselines with those changes.
