MODE: Hail Verification
model_applications/short_range/MODE_fcstHRRR_obsMRMS_Hail_GRIB2.conf
Scientific Objective
To provide statistical inforation on the forecast hail size compared to the observed hail size from MRMS MESH data. Using objects to verify hail size avoids the “unfair penalty” issue, where a CAM must first generate convection to have any chance of accurately predicting the hail size. In addition, studies have shown that MRMS MESH observed hail sizes do not correlate one- to-one with observed sizes but can only be used to group storms into general categories. Running MODE allows a user to do this.
Version Added
METplus version 3.0
Datasets
Forecast: HRRRv4 data
Observation: MRMS
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 MODE to create object statistics on forecast hail size from the HRRR version 4 model and the observed MRMS MESH hail size.
METplus Workflow
Beginning time (VALID_BEG): 2019052902
End time (VALID_END): 2019052903
Increment between beginning and end times (VALID_INCREMENT): 3600
The MODE tool is run for each time. This example loops by valid time. It processes 2 valid times, 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/MODE_fcstHRRR_obsMRMS_Hail_GRIB2.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
