This real-time forecast system is being set up to test the latest HRRR-like physics in a CONUS MPAS domain with 3-km cell spacing. This run ("dev2") is heavily linked to "dev1" and ideally will be used to assess the impacts of a single difference or a small number of differences relative to dev1. Initial and boundary conditions come from the operational Rapid Refresh model. Documentation of the MPAS model code used for these real-time forecasts is available here: https://github.com/NOAA-GSL/MPAS-Model/ David Dowell, 6/17/2024 ----------------------- 6/17/2024 (18Z): started real-time runs with GF convection included in physics suite; currently, the only difference relative to mpas_physics_dev1 is the following in namelist.atmosphere: dev2: config_convection_scheme = 'cu_grell_freitas' dev1: config_convection_scheme = 'off' 6/18/2024 (18Z): added hpbl to the MPASSIT histlist_2d 6/19/2024 (12Z): turned off GWD in namelist.atmosphere: config_gwdo_scheme = 'off' 6/20/2024 (18Z): added ivgtyp to the MPASSIT histlist_2d 6/25/2024 (00Z): updated init_atmosphere_model and atmosphere_model executables, which lead to model crashes after writing out state at t=0 6/26/2024 (03Z): changed init_atmosphere_model and atmosphere_model executables back to June 17 versions 6/26/2024 (06Z): upgraded UPP to authoritative version and changed python graphics to be consistent with grib2 changes;
