MPAS ATM bug-fixes

• Fixed 2m and 10m fields not being updated - set istatus for VERTISHEIGHT and VERTISLEVEL for convert_vert_distrib_state. #756
  thanks to Matt Wilson for reporting this
• Fixed vertical location in convert_vertical_obs to use zGridFace. #524

POP initial ensemble available from GDEX

Documentation update:

• POP initial ensemble available from Geoscience Data Exchange (GDEX) #476

Bug-fixes:

• Removed unnecessary loops around calendar types in time_manager_mod. #653
• Removed unused routine from normal_distribution_mod which caused compilation warnings. #736
• Replaced broadcast_minmax calls with all_reduce_min_max. #762

MPI window memory reduction

• Removes unnecessary copy of state into MPI window.
• Removes cray pointer version of the MI window.

We do not expect this internal change to the MPI window to affect users, however if this change causes problems with particular MPI libraries or you are making use of the cray-pointer window, please reach out to dart@ucar.edu

• Fortran-testanything included in developer tests.
  From dennisdjensen: see developer_tests/contrib/fortran-testanything/LICENSE.txt

Bug-fixes: WRF and GOES

• It is now mandatory to use THM as the Temperature variable (type_t) in the WRF model_nml #728
• Removed the offset in the GOES observation converter #731
  Please be aware that when using RTTOV with DART you should confirm that the channels listed in the coefficient file match the channel in the obs_seq.out
  For more detail refer to the obs_def_rttov documentation

MOM6 mask bug-fix

• Fix for MOM6 CESM3 workhorse 2/3 degree grid TL319_t232 to mask missing geolon|lat|u|v|t values
