GENERATED FROM PYTHON SOURCE LINES 10-16 Scientific Objective -------------------- To provide useful statistical information on the relationship between observation data (in both grid and point formats) to an ensemble forecast. These values can be used to help correct ensemble member deviations from observed values. .. GENERATED FROM PYTHON SOURCE LINES 19-40 Datasets -------- | **Forecast:** WRF ARW 24 hour precipitation accumulation | ...met_test/data/sample_fcst/2009123112/ | arw-fer-gep1/d01_2009123112_02400.grib | arw-fer-gep5/d01_2009123112_02400.grib | arw-sch-gep2/d01_2009123112_02400.grib | arw-sch-gep6/d01_2009123112_02400.grib | arw-tom-gep3/d01_2009123112_02400.grib | arw-tom-gep7/d01_2009123112_02400.grib | **Gridded Observation:** ST4 24 hour precipitation accumulation | met_test/data/sample_obs/ST4/sample_obs/ST4/ST4.2010010112.24h | **Point Observation:** | met_test/out/ascii2nc/precip24_2010010112.nc | **Location:** All of the input data required for this use case can be found in the met_test sample data tarball. Click here to the METplus releases page and download sample data for the appropriate release: https://github.com/dtcenter/METplus/releases | The tarball should be unpacked into the directory that you will set the value of INPUT_BASE. See `Running METplus`_ section for more information. | **Data Source:** Unknown | .. GENERATED FROM PYTHON SOURCE LINES 42-48 METplus Components ------------------ This use case utilizes the METplus EnsembleStat wrapper to search for files that are valid at a given run time and generate a command to run the MET tool EnsembleStat if all required files are found. .. GENERATED FROM PYTHON SOURCE LINES 50-59 METplus Workflow ---------------- EnsembleStat is the only tool called in this example. It processes the following run times: | **Init:** 2009-12-31_12Z | **Forecast lead:** 24 hour | .. GENERATED FROM PYTHON SOURCE LINES 61-70 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/EnsembleStat/EnsembleStat.conf .. highlight:: bash .. literalinclude:: ../../../../parm/use_cases/met_tool_wrapper/EnsembleStat/EnsembleStat.conf .. GENERATED FROM PYTHON SOURCE LINES 72-87 MET Configuration ----------------- METplus sets environment variables based on user settings in the METplus configuration file. See :ref:`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: :ref:`Overriding Unsupported MET config file settings` .. note:: See the :ref:`EnsembleStat MET Configuration` section of the User's Guide for more information on the environment variables used in the file below: .. highlight:: bash .. literalinclude:: ../../../../parm/met_config/EnsembleStatConfig_wrapped .. GENERATED FROM PYTHON SOURCE LINES 89-113 Running METplus --------------- It is recommended to run this use case by: Passing in EnsembleStat.conf then a user-specific system configuration file:: run_metplus.py /path/to/METplus/parm/use_cases/met_tool_wrapper/EnsembleStat/EnsembleStat.conf /path/to/user_system.conf The following METplus configuration variables must be set correctly to run this example.: * **INPUT_BASE** - Path to directory where sample data tarballs are unpacked (See Datasets section to obtain tarballs). * **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. .. GENERATED FROM PYTHON SOURCE LINES 117-137 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 ensemble/200912311200/ensemble_stat (relative to **OUTPUT_BASE**) and will contain the following files: * ensemble_stat_20100101_120000V.stat * ensemble_stat_20100101_120000V_ecnt.txt * ensemble_stat_20100101_120000V_rhist.txt * ensemble_stat_20100101_120000V_phist.txt * ensemble_stat_20100101_120000V_orank.txt * ensemble_stat_20100101_120000V_ssvar.txt * ensemble_stat_20100101_120000V_relp.txt * ensemble_stat_20100101_120000V_ens.nc * ensemble_stat_20100101_120000V_orank.nc ..
