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 29-36 Datasets -------- | **Forecast:** 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) | **Location:** Click here for 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 `Running METplus`_ section for more information. .. GENERATED FROM PYTHON SOURCE LINES 38-45 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 47-59 METplus Workflow ---------------- 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 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 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 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:`GridStat 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/GridStatConfig_wrapped .. GENERATED FROM PYTHON SOURCE LINES 89-98 Python Embedding ---------------- This use case uses one Python embedding script with GridStat to read the input observation data 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 .. GENERATED FROM PYTHON SOURCE LINES 101-111 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 113-127 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 ..
