GENERATED FROM PYTHON SOURCE LINES 9-13 .. contents:: :depth: 1 :local: :backlinks: none .. GENERATED FROM PYTHON SOURCE LINES 15-20 Scientific Objective -------------------- To provide useful statistical information on the relationship between observation data in gridded format to a gridded forecast. These values can be used to help correct model deviations from observed values. .. GENERATED FROM PYTHON SOURCE LINES 22-26 Version Added ------------- METplus version 3.0 .. GENERATED FROM PYTHON SOURCE LINES 28-45 Datasets -------- **Forecast:** NOAA Global Forecast System (GFS) **Observation:** NOAA Global Forecast System (GFS) analysis **Climotology:** NCEP-NCAR 40-year Reanalysis (daily 1 degree global) **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 47-54 METplus Components ------------------ This use case utilizes the METplus GridStat wrapper to search for files that are valid at a given run time and generate a command to run the MET tool grid_stat if all required files are found. Then StatAnalysis is run on the GridStat output. .. GENERATED FROM PYTHON SOURCE LINES 56-80 METplus Workflow ---------------- **Beginning time (VALID_BEG):** 2017061300 **End time (VALID_END):** 2017061306 **Increment between beginning and end times (VALID_INCREMENT):** 21600 **Sequence of forecast leads to process (LEAD_SEQ):** 24, 48 GridStat and StatAnalysis are the tools called in this example. It processes the following run times: | **Valid:** 2017-06-13 0Z | **Forecast lead:** 24 hour | | **Valid:** 2017-06-13 0Z | **Forecast lead:** 48 hour | | **Valid:** 2017-06-13 6Z | **Forecast lead:** 24 hour | | **Valid:** 2017-06-13 6Z | **Forecast lead:** 48 hour .. GENERATED FROM PYTHON SOURCE LINES 82-91 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/medium_range/GridStat_fcstGFS_obsGFS_climoNCEP_MultiField.conf .. highlight:: bash .. literalinclude:: ../../../../parm/use_cases/model_applications/medium_range/GridStat_fcstGFS_obsGFS_climoNCEP_MultiField.conf .. GENERATED FROM PYTHON SOURCE LINES 93-111 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 .. dropdown:: StatAnalysisConfig_wrapped .. literalinclude:: ../../../../parm/met_config/STATAnalysisConfig_wrapped .. GENERATED FROM PYTHON SOURCE LINES 113-117 Python Embedding ---------------- This use case does not use Python embedding. .. GENERATED FROM PYTHON SOURCE LINES 119-123 User Scripting -------------- User Scripting is not used in this use case. .. GENERATED FROM PYTHON SOURCE LINES 125-134 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/medium_range/GridStat_fcstGFS_obsGFS_climoNCEP_MultiField.conf /path/to/user_system.conf See :ref:`running-metplus` for more information. .. GENERATED FROM PYTHON SOURCE LINES 136-149 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 gather_by_date/stat_analysis/grid2grid/anom (relative to **OUTPUT_BASE**) and will contain the following files:: * 00Z/GFS/GFS_20170613.stat * 06Z/GFS/GFS_20170613.stat ..
