MADIS2NC: Basic Use Case
met_tool_wrapper/MADIS2NC/MADIS2NC.conf
Scientific Objective
Converting file formats so point observations can be read by the MET tools.
Datasets
METplus Components
This use case utilizes the METplus MADIS2NC wrapper to generate a command to run the MET tool madis2nc if all required files are found.
METplus Workflow
MADIS2NC is the only tool called in this example. It processes the following run time:
METplus Configuration
METplus first loads the default configuration file found in parm/metplus_config, then it loads any configuration files passed to METplus via the command line.

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
Note
See the MADIS2NC MET Configuration section of the User’s Guide for more information on the environment variables used in the file below:
////////////////////////////////////////////////////////////////////////////////
//
// MADIS2NC configuration file.

////////////////////////////////////////////////////////////////////////////////
//
// The parameters listed below are used to summarize the MADIS data read in
//
//
// Time periods for the summarization
// obs_var (string array) is added and works like grib_code (int array)
// when the obs name is given instead of grib_code
//
//time_summary = {

Running METplus
Pass the path to MADIS2NC.conf as an argument to run_metplus.py:
run_metplus.py /path/to/METplus/parm/use_cases/met_tool_wrapper/MADIS2NC/MADIS2NC.conf
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 madis2nc (relative to OUTPUT_BASE) and will contain the following file:
met_metar_2012040912_F000.nc
