This real-time MPAS forecast is for a CONUS domain with 3-km cell spacing.
Initial conditions come from the experimental RRFS_A on WCOSS2.
The atmosphere_model executable will be updated often to include the latest changes to the HRRR-like physics suite.
Documentation of the MPAS model code used for these real-time forecasts is available here:

-----------------------
7/10/2024: began real-time forecasts
7/13/2024 (09Z): changed source of boundary conditions from RRFS to RAP
7/13/2024 (12Z): in namelist.init_atmosphere, changed config_use_spechumd = false to config_use_spechumd = true
This change will result in some needed drying at low levels.
7/16/2024 (18Z): turned on double-moment graupel/hail by adding "config_thompson_hail_aware = true" to namelist.atmosphere
7/20/2024 (12Z): updated mpassit executable to latest version and updated namelist.mpassit; MPAS output will now
be interpolated to a Lambert conformal grid as specified in the namelist rather than by the
fix geo file; the interpolated wind field will now be grid relative rather than earth relative
7/25/2024 (12Z): changed config_landuse_data from 'MODIFIED_IGBP_MODIS_NOAH' to 'MODIFIED_IGBP_MODIS_NOAH_15s'
in the &data_sources section of namelist.init_atmosphere

https://github.com/NOAA-GSL/MPAS-Model/pull/46
https://github.com/NOAA-GSL/MPAS-Model/pull/43
https://github.com/NOAA-GSL/MPAS-Model/pull/42
https://github.com/NOAA-GSL/MPAS-Model/pull/41

* added related lines to streams.atmosphere
* specified config_gwdo_scheme in namelist.atmosphere
8/03/2024 (12Z): in workflow, changed WPS_GEOG_PATH to "/mnt/lfs5/BMC/wrfruc/HRRRv5/geog/" so that
topo_ugwp_2.5m and topo_ugwp_30s will be available to init_atmosphere
8/04/2024 (12Z): extended forecast length from 42 to 48 h
8/08/2024 (00Z): added olrtoa / OLR to MPASSIT diagnostic output fields

and (2) initialization of vegetation arrays
https://github.com/NOAA-GSL/MPAS-Model/pull/47
https://github.com/NOAA-GSL/MPAS-Model/pull/48
9/04/2024 (12Z): added shdmin, shdmax, and canwat to stream_list.atmosphere.output

https://github.com/NOAA-GSL/MPAS-Model/pull/49
9/04/2024 (12Z): added vegfra, shdmin, shdmax, and canwat to MPASSIT histlist_2d
9/04/2024 (12Z): fixed bug in Vtable.RRFS for CANWAT, added new field VEGFRA
9/04/2024 (12Z): added config_soilcat_data = 'BNU' to the &data_sources section of namelist.init_atmosphere
added config_nvegopt = 2 to namelist.init_atmosphere
added config_gvf_update = false to namelist.atmosphere
9/06/2024 (12Z): turned on initialization of shdmin and shdmax from fix files, with more realistic values than
what was being produced internally within MPAS
9/25/2024 (12Z): updated UPP to latest version (upp.x, postxconfig-NT-rrfs_mpas.txt, and associated changes to upp.sh);
this update also removes a dependency of the post processing on template HRRR grib2 files
9/26/2024 (18Z): added snowc / SNOWC, snownc / SNOWNC, and graupelnc / GRAUPELNC to MPAS stream_list.atmosphere.output
and MPASSIT histlist_2d
9/27/2024 (12Z): added acrunoff / ACRUNOFF to MPASSIT histlist_2d
10/01/2024 (18Z): corrected Vtable.RRFS for the following variables: PMSL
added the following variables to Vtable.RRFS: QNR, QNC, QNI, SHDMIN, SHDMAX, QNWFA, QNIFA
turned off RESET_VEG_MIN_AND_MAX in model initialization (no longer needed because SHDMIN
and SHDMAX are now in RRFS_A grib2 output)
10/01/2024 (21Z): turned on more detailed log output with the following settings in namelist.atmosphere:
config_print_detailed_minmax_vel = true
config_print_global_minmax_sca = true
10/03/2024 (12Z): turned on copying of number concentrations of water- and ice-friendly aerosols (nwfa and nifa)
from HRRRv5 initial conditions to MPAS_RRFSA initial conditions
10/04/2024 (00Z): changed SOILPARM.TBL and VEGPARM.TBL
10/08/2024 (00Z): backed out the Oct 4 changes, which were mistakes; SOILPARM.TBL and VEGPARM.TBL are now the same
as what we used before Oct 4
10/17/2024 (12Z): updated UPP executable, with a bug fix that will result in the correct (non-zero) values of
latent heat flux appearing in the grib2 output and python plots
10/22/2024 (12Z): changed init_atmosphere_model and atmosphere_model to most recent GSL MPAS 8.1 version
(hash number 3ce58de of https://github.com/NOAA-GSL/MPAS-Model/); MPAS_RRFSA forecasts will
be unaffected by this change
10/22/2024 (18Z): updated mpassit to the most recent version (hash number bd91387 of https://github.com/LarissaReames-NOAA/MPASSIT);
refl10cm has been removed temporarily from the list of diagnostic variables owing to a bug that affects
this variable; otherwise, no output changes are expected
10/25/2024 (18Z): updated mpassit (https://github.com/LarissaReames-NOAA/MPASSIT/pull/43) and UPP, with some bug fixes from Eric James
that affect output of precipitation variables
10/26/2024 (12Z): restored refl10cm to list of diagnostic variables processed by mpassit
11/07/2024 (00Z): corrected units (from m to in) for cycled snow depth in python plots
11/08/2024 (15Z): for source of boundary conditions, changed from RAP data on 130 grid to RAP data on full rotated lat lon grid,
to be consistent with the RRFS workflow
11/19/2024 (12Z): changed from RAP to RRFS as source of boundary conditions; increased forecast length to 60 hours
11/19/2024 (18Z): changed ungrib version from WPSv3.9.0.1 to WPSv4.6.0
11/20/2024 (12Z): added nc (QNCLOUD) and ng (QNGRAUP) to MPASSIT histlist_3d.THOM
11/22/2024 (06Z): added swddir, swddni, and swddif to MPAS diagnostic output (stream_list.atmosphere.diagnostics)
11/22/2024 (12Z): added SWDDIR, SWDDNI, and SWDDIF to MPASSIT diagnostic output
11/28/2024 (00Z): water- and ice-friendly aerosol number concentrations because available in the RRFS_A grib2 output
11/28/2024 (12Z): added graupel particle volume (volg / VOLG) to MPASSIT output
11/29/2024 (12Z): turned off copying of RAP aerosol number concentrations to initial conditions so that
RRFS_A aerosol number concentrations will be used instead
12/04/2024 (00Z): changed init_atmosphere_model and and atmosphere_model to versions compiled with spack stack (1.6.0)
12/05/2024 (18Z): upgraded UPP, with the following changes: (1) output of cloud-ice mixing ratio ("ICMR"), graupel mixing ratio ("GRLE"),
ice-friendly aerosol number concentration ("PMTC"), water-friendly aerosol number concentration ("PMTF")
and (2) bug fixes for GOES brightness temperatures
------------------------------------------
12/04/2024 (00Z): *** RRFS_A on WCOSS turned off ***
MPAS_RRFSA forecasts will be unavailable until RRFS_A is turned back on (currently anticipated to happen in Feburary 2025)
