Configure

MODE Tool: Configure

Start by making an output directory for MODE and changing directories:

mkdir -p ${METPLUS_TUTORIAL_DIR}/output/met_output/mode

cd ${METPLUS_TUTORIAL_DIR}/output/met_output/mode

The behavior of MODE is controlled by the contents of the configuration file passed to it on the command line. The default MODE configuration file may be found in the data/config/MODEConfig_default file.

Prior to modifying the configuration file, users are advised to make copies of existing configuration files:

cp ${METPLUS_DATA}/met_test/scripts/config/MODEConfig_APCP_12 MODEConfig_APCP_12

cp ${METPLUS_DATA}/met_test/scripts/config/MODEConfig_APCP_24 MODEConfig_APCP_24

cp ${METPLUS_DATA}/met_test/scripts/config/MODEConfig_RH MODEConfig_RH

We'll be using these three configuration files during this session.

Open up the MODEConfig_APCP_12 file to view it.

vi MODEConfig_APCP_12

The configuration items for MODE are used to specify how the object-based verification approach is to be performed. In MODE, as in the other MET statistics tools, you can compare any two fields. When necessary, the items in the configuration file are specified separately for the forecast and observation fields. In most cases though, users will be comparing the same forecast and observation fields. The configurable items include parameters for the following:

The forecast and observation fields and vertical levels or accumulation intervals to be compared
Options to mask out a portion of or threshold the raw fields
The forecast and observation object definition parameters
Options to filter out objects that don't meet a size or intensity criteria
Flags to control the logic for matching/merging
Weights to be applied for the fuzzy engine matching/merging algorithm
Interest functions to be used for the fuzzy engine matching/merging algorithm
Total interest threshold for matching/merging
Various plotting options

While the MODE configuration file contains many options, beginning users will typically only need to modify a few of them. You may find a complete description of the configurable items in the mode configuration file section of the MET User's Guide. Please take some time to review them.

At the bottom of MODE_Config_APCP_12, change "version" to "11.0"

////////////////////////////////////////////////////////////////////////////////

output_prefix = "";
version = "V11.0";

////////////////////////////////////////////////////////////////////////////////

Close MODEConfig_APCP_12. Also change the version number in MODEConfig_APCP_24 and MODEConfig_RH.

We'll start here using by running the configuration files we copied over, as-is.
