GENERATED FROM PYTHON SOURCE LINES 9-13 .. contents:: :depth: 1 :local: :backlinks: none .. GENERATED FROM PYTHON SOURCE LINES 15-21 Scientific Objective -------------------- Evaluate the skill of a high resolution multi-model ensemble mean at predicting 6 hour precipitation accumulation using the NCEP Stage IV gauge corrected analysis. .. GENERATED FROM PYTHON SOURCE LINES 23-27 Version Added ------------- METplus version 3.0 .. GENERATED FROM PYTHON SOURCE LINES 29-46 Datasets -------- **Forecast:** NOAA High Resolution Ensemble Forecast (HREF) mean forecasts in Gempak **Observation:** Stage IV GRIB 6 hour precipitation accumulation **Climatology:** None **Location:** All of the input data required for this use case can be found in a sample data tarball. Each use case category will have one or more sample data tarballs. It is only necessary to download the tarball with the use case’s dataset and not the entire collection of sample data. Click here to access the METplus releases page and download sample data for the appropriate release: https://github.com/dtcenter/METplus/releases This tarball should be unpacked into the directory that you will set the value of INPUT_BASE. See :ref:`running-metplus` section for more information. .. GENERATED FROM PYTHON SOURCE LINES 48-65 External Dependencies --------------------- GempakToCF.jar GempakToCF is an external tool that utilizes the Unidata NetCDF-Java package. The jar file that can be used to run the utility is available here: https://dtcenter.org/sites/default/files/community-code/metplus/utilities/GempakToCF.jar To enable Gempak support, you must set [exe] GEMPAKTOCF_JAR in your user METplus configuration file: [exe] GEMPAKTOCF_JAR = /path/to/GempakToCF.jar See the GempakToCF use case for more information: parm/use_cases/met_tool_wrapper/GempakToCF/GempakToCF.conf More information on the package used to create the file is here: https://www.unidata.ucar.edu/software/netcdf-java .. GENERATED FROM PYTHON SOURCE LINES 67-74 METplus Components ------------------ This use case first runs PCPCombine on the forecast data to build a 6 hour precipitation accumulation from 1 hour files or a single 6 hour file. Then the observation data is regridded to the model grid using the RegridDataPlane. Finally, the observation files are compared to the forecast data using GridStat. .. GENERATED FROM PYTHON SOURCE LINES 76-98 METplus Workflow ---------------- **Beginning time (INIT_BEG):** 2017050912 **End time (INIT_END):** 2017050912 **Increment between beginning and end times (INIT_INCREMENT):** 43200 **Sequence of forecast leads to process (LEAD_SEQ):** 18 The following tools are used for each run time: PCPCombine (observation) > RegridDataPlane (observation) > GridStat This example loops by initialization time. There is only one initalization time in this example so the following will be run: Run times: | **Init:** 2017-05-09_12Z | **Forecast lead:** 18 .. GENERATED FROM PYTHON SOURCE LINES 100-110 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, i.e. parm/use_cases/model_applications/precipitation/GridStat_fcstHREFmean_obsStgIV_Gempak.conf .. highlight:: bash .. literalinclude:: ../../../../parm/use_cases/model_applications/precipitation/GridStat_fcstHREFmean_obsStgIV_Gempak.conf .. GENERATED FROM PYTHON SOURCE LINES 112-126 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` .. dropdown:: GridStatConfig_wrapped .. literalinclude:: ../../../../parm/met_config/GridStatConfig_wrapped .. GENERATED FROM PYTHON SOURCE LINES 128-132 Python Embedding ---------------- This use case does not use Python embedding. .. GENERATED FROM PYTHON SOURCE LINES 134-138 User Scripting -------------- User Scripting is not used in this use case. .. GENERATED FROM PYTHON SOURCE LINES 140-149 Running METplus --------------- Pass the use case configuration file to the run_metplus.py script along with any user-specific system configuration files if desired:: run_metplus.py /path/to/METplus/parm/use_cases/model_applications/precipitation/GridStat_fcstHREFmean_obsStgIV_Gempak.conf /path/to/user_system.conf See :ref:`running-metplus` for more information. .. GENERATED FROM PYTHON SOURCE LINES 151-166 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 model_applications/precipitation/GridStat_fcstHREFmean_obsStgIV_Gempak/GridStat/201705091200 (relative to **OUTPUT_BASE**) and will contain the following files: * grid_stat_000000L_20170510_060000V_eclv.txt * grid_stat_000000L_20170510_060000V_grad.txt * grid_stat_000000L_20170510_060000V.stat ..
