| # Scientific Objective | ||
| # -------------------- | ||
| # | ||
| # Run PCPCombine, EnsembleStat, and RegridDataPlane tools to create surrogate severe probability | ||
| # forecasts (SSPFs) for a given date. SSPFs are a severe weather forecasting tool and is a techniqu | ||
| # used by the Storm Prediction Center (SPC) as well as others. SSPFs are based on updraft helicity | ||
| # (UH; UH = ∫z0 to zt (ω * ζ) dz) since certain thresholds of UH have been shown as good proxies for# severe weather. SSPFs can be thought of as the perfect model forecast. They are derived as follows: | ||
| # 1. Regrid the maximum UH value over the 2-5km layer at each grid point to the NCEP 211 grid (dx = ~80km). | ||
| # 2. Create a binary mask of points that meet a given threshold of UH) | ||
| # 3. Convert the binary mask into a probability field by applying a Gaussian filter. | ||
| # | ||

| # Datasets | ||
| # -------- | ||
| # | ||
| # There are two dates that can be used as input data for this use case 20190518 or 20200205. | ||
| # | ||
| # * Input Data: HRRR data | ||
| # - There should 24 grib2 files. | ||
| # - Variable of interest: MXUPHL; the maximum updraft helicity | ||
| # - Level: Z2000-5000; from 2 - 5km | ||
| # - Format: grib2 | ||
| # - Projection: Lambert Conformal | ||

| # METplus Components | ||
| # ------------------ | ||
| # | ||
| # This use case runs the PCPCombine, EnsembleStat, and RegridDataPlane MET tools. | ||
|
|
||
| ################################################################################################### | ||
| # METplus Workflow | ||
| # ---------------- | ||
| # | ||
| # This workflow loops over the data by process, meaning that each MET tool will run over all times | ||
| # before moving onto the tool. PCPCombine is called first, followed by EnsembleStat, | ||
| # and then, finally, RegridDataPlane. | ||
|
|
||
| ################################################################################################### | ||
| # METplus Configuration | ||
| # --------------------- | ||
| # | ||
| # METplus first loads all of the configuration files found in parm/metplus_config. Then, it loads | ||
| # any configuration files passed to METplus by the command line with the -c option. | ||
| # | ||
| # .. highlight:: bash | ||
| # .. literalinclude:: ../../../../parm/use_cases/model_applications/convection_allowing_models/EnsembleStat_fcstHRRR_fcstOnly_SurrogateSevere.conf | ||
|
|
||
| ################################################################################################### | ||
| # MET Configuration | ||
| # ----------------- | ||
| # | ||
| # METplus sets environment variables based on the values in the METplus configuration file. | ||
| # These variables are referenced in the MET configuration file. **YOU SHOULD NOT SET ANY OF THESE ENVIRONMENT VARIABLES YOURSELF! THEY WILL BE OVERWRITTEN BY METPLUS WHEN IT CALLS THE MET TOOLS!** If there is a setting in the MET configuration file that is not controlled by an environment variable, you can add additional environment variables to be set only within the METplus environment using the [user_env_vars] section of the METplus configuration files. See the 'User Defined Config' section on the 'System Configuration' page of the METplus User's Guide for more information. | ||
| # | ||
| # **EnsembleStatConfig_Surrogate_severe** | ||
| # | ||
| # .. highlight:: bash | ||
| # .. literalinclude:: ../../../../parm/use_cases/model_applications/convection_allowing_models/EnsembleStatConfig_Surrogate_severe | ||
| # | ||
| # See the following file for more information about the environment variables set in this configuration file: | ||
| # parm/use_cases/met_tool_wrapper/EnsembleStat/EnsembleStat.py | ||
|
|
||
| ################################################################################################### | ||
| # Running METplus | ||
| # --------------- | ||
| # | ||
| # The command to run this use case is:: | ||
| # | ||
| # master_metplus.py -c /path/to/METplus/parm/use_cases/model_applications/convection_allowing_models/EnsembleStat_fcstHRRR_fcstOnly_SurrogateSevere.conf | ||
|
|
||
| ################################################################################################### | ||
| # Expected Output | ||
| # --------------- | ||
|
|
||
| # A successful run of this use case will output the following to the screen and logfile:: | ||
| # | ||
| # INFO: METplus has successfully finished runing. | ||
| # | ||
| # A successful run will have the following output files in the location defined by {OUTPUT_BASE}, which | ||
| # is located in the metplus_system.conf configuration file located in /path/to/METplus/parm/metplus_config. | ||
| # This list of files should be found for every time run through METplus. Using the output for 20190518 as an example. | ||
| # | ||
| # **PCPCombine output**: | ||
| # | ||
| # * 20190518/hrrr_ncep_2019051800f036.nc | ||
| # | ||
| # **EnsembleStat output**: | ||
| # | ||
| # * ensemble_stat_20190519_120000V_ens.nc | ||
| # | ||
| # **RegridDataPlane output**: | ||
| # | ||
| # * surrogate_severe_20190518_036V_regrid.nc | ||
