METplus Use Case: MTD
Reference Material
The MTD (Mode Time Domain) use case utilizes the MET MTD tools.
Optional: Refer to the MET Users Guide for a description of the MET tools used in this use case.
Optional: Refer to the A-Z Config Glossary section of the METplus Users Guide for a reference to METplus variables used in this use case.
Review Use Case Configuration File: MTD.conf
Note that there are options to specify to run the tool with one file or two, depending on the science question being answered, as well configuration options for the settings regularly adjusted by users. For example:
MTD_SINGLE_DATA_SRC = OBS
FCST_MTD_CONV_RADIUS = 0
FCST_MTD_CONV_THRESH = >=10
OBS_MTD_CONV_RADIUS = 15
OBS_MTD_CONV_THRESH = >=1.0
Also note that there is a configuration option to run MTD variables in MTD.conf reference other config variables that have been defined in other configuration files. For example:
This references INPUT_BASE which is set in the METplus data configuration file (metplus_config/metplus_data.conf). METplus config variables can reference other config variables even if they are defined in a config file that is read afterwards.
Run METplus
${METPLUS_BUILD_BASE}/parm/use_cases/met_tool_wrapper/MTD/MTD.conf \
${METPLUS_TUTORIAL_DIR}/tutorial.conf \
config.OUTPUT_BASE=${METPLUS_TUTORIAL_DIR}/output/MTD
METplus is finished running when control returns to your terminal console and you see the following text:
INFO: METplus has successfully finished running as user.
