5.1.11.2. MODE: Basic Use Case
met_tool_wrapper/MODE/MODE.conf
Scientific Objective
Compare relative humidity 12 hour forecast to 0 hour observations. Generate statistics of the results.
Datasets
METplus Components
This use case utilizes the METplus MODE wrapper to search for files that are valid at a given run time and generate a command to run the MET tool mode if all required files are found.
METplus Workflow
MODE is the only tool called in this example. It processes the following run times:
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 with the -c option, i.e. -c parm/use_cases/met_tool_wrapper/MODE/MODE.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

Running METplus
This use case can be run two ways:
Passing in MODE.conf then a user-specific system configuration file:
run_metplus.py -c /path/to/METplus/parm/use_cases/met_tool_wrapper/MODE/MODE.conf -c /path/to/user_system.conf
Modifying the configurations in parm/metplus_config, then passing in MODE.conf:
run_metplus.py -c /path/to/METplus/parm/use_cases/met_tool_wrapper/MODE/MODE.conf
The former method is recommended. Whether you add them to a user-specific configuration file or modify the metplus_config files, the following variables must be set correctly:
INPUT_BASE - Path to directory where sample data tarballs are unpacked (See Datasets section to obtain tarballs). This is not required to run METplus, but it is required to run the examples in parm/use_cases
OUTPUT_BASE - Path where METplus output will be written. This must be in a location where you have write permissions
MET_INSTALL_DIR - Path to location where MET is installed locally
Example User Configuration File:
[dir]
INPUT_BASE = /path/to/sample/input/data
OUTPUT_BASE = /path/to/output/dir
MET_INSTALL_DIR = /path/to/met-X.Y
NOTE: All of these items must be found under the [dir] section.
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 mode/2005080712 (relative to OUTPUT_BASE) and will contain the following files:
# * mode_WRF_RH_vs_WRF_RH_P500_120000L_20050807_120000V_000000A_cts.txt
