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: https://github.com/NOAA-GSL/MPAS-Model/ David Dowell, 7/10/2024 ----------------------- 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;

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
