Grid-Stat: Surrogate Severe and Practically Perfect Probabilistic Evaluation
model_applications/short_range/GridStat_fcstHRRR_obsPracPerfect_SurrogateSevereProb.conf
Scientific Objective
To evaluate the surrogate severe forecasts at predicting Severe weather using the (12Z - 12Z) practically perfect storm reports an obtain probabilistic output statistics.
Version Added
METplus version 3.1
Datasets
Forecast: HRRR Surrogate Severe Data
Observation: Practically Perfect from Local Storm Reports
Climatology: None
Location: All of the input data required for this use case can be found in a sample data tarball. Each use case category will have one or more sample data tarballs. It is only necessary to download the tarball with the use case’s dataset and not the entire collection of sample data. Click here to access the METplus releases page and download sample data for the appropriate release: https://github.com/dtcenter/METplus/releases This tarball should be unpacked into the directory that you will set the value of INPUT_BASE. See Running METplus section for more information.
METplus Components
This use case runs grid_stat to create probabilistic statistics on surrogate severe from the HRRR model and Practially Perfect observations computed from local storm reports.
METplus Workflow
Beginning time (VALID_BEG): 2020020612
End time (VALID_END): 2020020612
Increment between beginning and end times (VALID_INCREMENT): 86400
The grid_stat tool is run for each time. This example loops by valid time. It processes 1 valid time, listed below.
METplus Configuration
METplus first loads all of the configuration files found in parm/metplus_config, then it loads any configuration files passed to METplus via the command line, i.e. parm/use_cases/model_applications/short_range/GridStat_fcstHRRR_obsPracPerfect_SurrogateSevere.conf

MET Configuration
METplus sets environment variables based on user settings in the METplus configuration file. See How METplus controls MET config file settings for more details.
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 currently not supported by METplus you’d like to control, please refer to: Overriding Unsupported MET config file settings

Expected Output
A successful run will output the following both to the screen and to the logfile:
INFO: METplus has successfully finished running.
Refer to the value set for OUTPUT_BASE to find where the output data was generated. Output for this use case will be found in model_applications/short_range/surrogate_severe_prac_perfect/grid_stat/prob (relative to OUTPUT_BASE) and will contain the following files:
