| \item Add data file, \execout{suite\_sim\_file} created in \ref{section:Creating_Custom_Data_for_Simulator} to the namelist. | ||

fix reference here - should point to listing 7.2

| For example, in Listing \ref{lst_css_nml}, there are two active schemes, longwave and shortwave radiaiton, and five simulated schemes: PBL, gravity-wave drag, deep/shallow convection, and cloud microphysics. The radiation, gravity-wave drag and PBL schemes are all process-split, whereas convection and cloud microphysics are time-split. |

It seems this is still pointing to the wrong Listing (looking at the most updated pdf)
| nfiles = 0 | ||
| fileSCM = [] | ||
| for nml in namelist: | ||
| fileSCM.append("../../../../scm/run/output_" + case_name + "_" + suite+"_"+nml+"/output.nc") |

This does not work for my test runs as the 'nml' is not appended to my case directory.
For example, when executing this script, it looks for
../../../../scm/run/output_MAGIC_LEG15A_SCM_GFS_v17_p8_input_GFS_v17_p8/output.nc does not exist.
But it is named:
../../../run/output_MAGIC_LEG15A_SCM_GFS_v17_p8/output.nc
It looks like the 3d works in this way as well.

@hertneky Good catch. It should be fixed now.

@dustinswales In input_GFS_v17_p8.nml, there is a parameter do_ccpp_suite_sim, but I don't see it documented. This looks like it is used by ccpp_suite_simulator.F90 and GFS_ccpp_suite_sim_pre.F90. Does this also need to exits and be turned on in the namelist? |
@hertneky Another good catch! |
|
@mkavulich This is ready to merge. Can you approve? |

@dustinswales Sorry this review is so late. The code changes look good but I have some minor documentation corrections. Otherwise good to go.

This PR adds a new functionality, a physics process scheme simulator, to the CCPP-physics.
Data-driven tendencies can be used to drive process schemes (e.g. PBL, Deep-Convection, etc..). The control over which schemes are used are set in a new physics namelist, scm_data_nml. These data tendencies are read in during the CCPP initialization stage, and applied during the _run stage, if requested by the nml. There are new interstitial variables for the data tendencies.
To use this feature on the host-model side the Suite Definition File (SDF) needs to be modified to include the ccpp_scheme_simulator scheme, and GFS_ccpp_scheme_sim_pre.
There are examples included that exercise this new tool. Documentation will follow.
