GENERATED FROM PYTHON SOURCE LINES 9-13 .. contents:: :depth: 1 :local: :backlinks: none .. GENERATED FROM PYTHON SOURCE LINES 15-21 Scientific Objective -------------------- To provide useful statistical information on the relationship between observation data in gridded format to a gridded forecast. The Ozone Monitoring Instrument (OMI) data covers a 36 hour period and is compared to the average of the gridded forecast files (all from the same initialization time). .. GENERATED FROM PYTHON SOURCE LINES 23-27 Version Added ------------- METplus version 6.0 .. GENERATED FROM PYTHON SOURCE LINES 29-46 Datasets -------- **Forecast:** NOAA Global Forecast System (GFS) (1 degree Lat/Lon grid) **Observation:** NASA's Level-3 Aura/OMI Global Total Ozone Mapping Spectrometer-Like (TOMS-Like) Total Column Ozone gridded product OMTO3e (0.25deg Lat/Lon grid) **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 48-55 METplus Components ------------------ This use case first runs PCPCombine on the forecast data to build a 36-hour Total Colum Ozone mean/average file. Then the forecast data are compared to the observation data using GridStat. This use case utilizes the METplus GridStat wrapper to read in the observation file using Python Embedding. .. GENERATED FROM PYTHON SOURCE LINES 57-77 METplus Workflow ---------------- **Beginning time (VALID_BEG):** 2023120506 **End time (VALID_END):** 2023120506 **Increment between beginning and end times (VALID_INCREMENT):** 21600 **Sequence of forecast leads to process (LEAD_SEQ):** 48 The following tools are used for each run time: PCPCombine (forecast) > GridStat It processes the following run times: | **Valid:** 2023-12-05 06Z (36 hour period covering 2023-12-03 18Z - 2023-12-05 06Z) | **Init:** 2023-12-03 06Z | **Forecast lead:** 48 .. GENERATED FROM PYTHON SOURCE LINES 79-88 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 parm/use_cases/model_applications/medium_range/GridStat_fcstGFS_obsOMI_TotalColumnOzone.conf .. highlight:: bash .. literalinclude:: ../../../../parm/use_cases/model_applications/medium_range/GridStat_fcstGFS_obsOMI_TotalColumnOzone.conf .. GENERATED FROM PYTHON SOURCE LINES 90-104 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 106-118 Python Embedding ---------------- This use case uses one Python embedding script with GridStat to read the input observation data. .. dropdown:: parm/use_cases/model_applications/medium_range/GridStat_fcstGFS_obsOMI_TotalColumnOzone/read_omi-aura_l3-omto3e.py .. highlight:: python .. literalinclude:: ../../../../parm/use_cases/model_applications/medium_range/GridStat_fcstGFS_obsOMI_TotalColumnOzone/read_omi-aura_l3-omto3e.py For more information on the basic requirements to utilize Python Embedding in METplus, please refer to the MET User’s Guide section on `Python embedding `_. .. GENERATED FROM PYTHON SOURCE LINES 120-124 User Scripting -------------- User Scripting is not used in this use case. .. GENERATED FROM PYTHON SOURCE LINES 126-136 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_obsOMI_TotalColumnOzone.conf /path/to/user_system.conf See :ref:`running-metplus` for more information. .. GENERATED FROM PYTHON SOURCE LINES 138-152 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/medium_range/GridStat_fcstGFS_obsOMI_TotalColumnOzone (relative to **OUTPUT_BASE**) and will contain the following files: * PCPCombine/pcp_combine.tozone_l0.mean.f048.init2023120306.nc * GridStat/grid_stat_GFS_vs_OMI_480000L_20231205_060000V.stat ..
