GENERATED FROM PYTHON SOURCE LINES 9-16 Scientific Objective -------------------- This use case captures various statistical measures of two model comparisons for low and total cloud fraction with different neighborhood and probability settings for internal model metrics and to aid in future model updates .. GENERATED FROM PYTHON SOURCE LINES 18-28 Datasets -------- | **Forecast:** Global Forecast System (GFS) | **Observations:** Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA2) | **Grid:** GPP 17km masking region | **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 | 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 30-41 METplus Components ------------------ This use case utilizes Python Embedding, which is called using the PYTHON_NUMPY keyword in the observation input template settings. The same Python script processes both forecast and observation datasets, but only the observation dataset is not set up for native ingest by MET. Two separate forecast fields are verified against two respective observation fields, with the Python script being passed the input file, the model name, the variable name being analyzed, the initialization and valid times, and a flag to indicate if the field passed is observation or forecast. This process is repeated with 3 instance names to GridStat, each with a different setting for regridding, neighborhood evaluation, thresholding, output line types, and output prefix names. .. GENERATED FROM PYTHON SOURCE LINES 43-53 METplus Workflow ---------------- GridStat is the only MET tool called in this example. It processes the following run time: | **Init:** 2021-07-03 12Z | **Forecast lead:** 36 hour Because instance names are used, GridStat will run 3 times for this 1 initalization time. .. GENERATED FROM PYTHON SOURCE LINES 55-64 METplus Configuration --------------------- METplus first loads the default configuration file found in parm/metplus_config, then it loads any configuration files passed to METplus via the command line: parm/use_cases/model_applications/clouds/GridStat_fcstGFS_obsMERRA2_lowAndTotalCloudFrac.conf .. highlight:: bash .. literalinclude:: ../../../../parm/use_cases/model_applications/clouds/GridStat_fcstGFS_obsMERRA2_lowAndTotalCloudFrac.conf .. GENERATED FROM PYTHON SOURCE LINES 66-81 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 83-92 Python Embedding ---------------- This use case utilizes 1 Python script to read and process both forecast and observation fields. parm/use_cases/model_applications/clouds/GridStat_fcstGFS_obsMERRA2_lowAndTotalCloudFrac/read_input_data.py .. highlight:: bash .. literalinclude:: ../../../../parm/use_cases/model_applications/clouds/GridStat_fcstGFS_obsMERRA2_lowAndTotalCloudFrac/read_input_data.py .. GENERATED FROM PYTHON SOURCE LINES 94-103 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/clouds/GridStat_fcstGFS_obsMERRA2_lowAndTotalCloudFrac.conf /path/to/user_system.conf See :ref:`running-metplus` for more information. .. GENERATED FROM PYTHON SOURCE LINES 105-123 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/clouds/GridStat_fcstGFS_obsMERRA2_lowAndTotalCloudFrac (relative to **OUTPUT_BASE**) and will contain the following files: * grid_stat_GFS_TO_MERRA2_F36_CloudFracs_360000L_20210705_000000V_pairs.nc * grid_stat_GFS_to_MERRA2_F36_CloudFracs_360000L_20210705_000000V.stat * grid_stat_GFS_to_MERRA2_F36_CloudFracs_NBR_360000L_20210705_000000V_pairs.nc * grid_stat_GFS_to_MERRA2_F36_CloudFracs_NBR_360000L_20210705_000000V.stat * grid_stat_GFS_to_MERRA2_F36_CloudFracs_PROB_360000L_20210705_000000V_pairs.nc * grid_stat_GFS_to_MERRA2_F36_CloudFracs_PROB_360000L_20210705_000000V.stat ..
