WRF use_theta_m check

• Assert use_theta_m=0 in WRF when initializing wrf model_mod. #837
  For use of THM vs T & use_theta_m in WRF refer to the WRF v4 release notes
• Fixed documentation broken links. #829

WRF tutorial and prepbufr documentation

• Observation section of WRF tutorial updated to match provided obs. #792
• Prepbufr docs updated to describe complete conversion process.

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

Inflation documentation

• Improved inflation documentation #775, #276
• CAM FV and SE checks for required state variables #662
• GitHub action to alert on files with legacy svn info #802
• Fwd op documentation formatting fix #797

Bug-fix: Explicitly handle BNRHF transform failures

• Probit transform failure is caught and an error code is returned
• filter_mod and assim_tools_mod skip variables that fail the transform

DART_LAB QCEFF

• DART_LAB updated to include QCEFF #739
• NSF NCAR RDA links updated #755
• /glade RDA locations updated #755

Bug-fix: Gamma and Beta Distributions

Bug fixes:

• Beta distribution only supporting standard Beta, bounded 0-1. #717
• Gamma distribution only supporting standard, lower bound 0. #786
• Beta and Gamma bounds are forced in the QCEFF table.

Updates:

• Explicitly setting distribution type, now have UNSET.
• Message about failing to converge changed to E_ALLMSG to be visible
  on all MPI ranks. If you get a significant increase in output, please email [email protected] to let us know
• remove unused test_obs directory #220

Bug-fix MOM6 potential temperature

• MOM6 model_interpolate for potential temperature #773
• Update lorenz workshop input.nmls to v11 #789

Bug-fix 1D obs_diag

• Added a dummy dimension so 1D obs_diag output can be used with
  MATLAB diagnostic tools #230
• Added a notification that probit inflation QCEFF options are ignored
  for RTPS (posterior inflation) #748
