We recommend you checkout the wrf-unified branch to get the latest developments on this code:

git checkout wrf-unified
git pull

Summary of changes:

• Unifies wrf and wrf_chem capabilities into a single model_mod
• removes wrf_static_data_for_data, uses state_stucture_mod
• Removed wrf%dom%type so any netcdf variables can be added to the state via namelsit
• 2M variables forced to 2M QTYs
• QTY_TEMPERATURE forced to QTY_POTENTIAL_TEMPERATURE
• No vortex forward operator

Generic model_mod subroutine parse_variables

• Creates two generalized subroutines in utilities/default_model_mod.f90 that convert the table of state variables that is read in from the &model_nml to a state_var_type: parse_variables and parse_variables_clamp (#783)
• Alternate versions for this subroutine were replaced with parse_variables in the models MOM6, wrf_hydro, aether_lat-lon, cam-fv, cam-se, POP, and cice
• New dev test test_parse_variables added
