GENERATED FROM PYTHON SOURCE LINES 9-13 .. contents:: :depth: 1 :local: :backlinks: none .. GENERATED FROM PYTHON SOURCE LINES 15-34 Overview -------- This use case illustrates the use of grid_stat tool for the space weather domain. It compares Total Electron Content for a GloTEC model run initialized with COSMIC-1 radio occultation (RO) data to a GloTEC model run without such data. In this use case, the forecast is considered to be the run without COSMIC-1 RO data. The observations are considered to be the run with COSMIC-1 RO data. This use case runs grid_stat for the first two forecast times of a space weather event known as the St. Patrick's Day Storm (Mar 17, 2015). Novel aspects of this use case: * This is the first example use case to run grid_stat on a space weather model (GloTEC) * Example of how to run with NetCDF input data which do not strictly conform to the Climate Forecasts (CF) conventions * Example of using masks covering latitudinal bands of interest to the space weather community: equatorial region, mid-latitude region, and polar region * Example of masking using the values of a quality flag which vary at each time step and grid point ..

GENERATED FROM PYTHON SOURCE LINES 42-48 Scientific Objective -------------------- Compare gridded forecast data from a run of the GloTEC model that includes assimilation of COSMIC-1 radio occultation (RO) observations to gridded forecast data from a GloTEC model run that does not include COSMIC-1 RO data. .. GENERATED FROM PYTHON SOURCE LINES 50-61 Datasets -------- | **Forecast:** GloTEC Total Electron Content (TEC) model run without assimilation of any COSMIC-1 RO data | **Observation:** GloTEC TEC model run that assimilates COSMIC-1 RO data | **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.

Vigh (National Center for Atmospheric Research / Research Applications Laboratory / Joint Numerical Testbed) | **Last modified:** 06 February 2020 | .. GENERATED FROM PYTHON SOURCE LINES 72-78 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. .. GENERATED FROM PYTHON SOURCE LINES 80-93 METplus Workflow ---------------- GridStat is the only tool called in this example. It processes the following run times: | **Init:** 2015-03-17 0005Z | **Forecast lead:** 0 | | **Init:** 2015-03-17 0015Z | **Forecast lead:** 0 | .. GENERATED FROM PYTHON SOURCE LINES 95-104 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 with the -c option, i.e. -c parm/use_cases/model_applications/space_weather/GridStat_fcstGloTEC_obsGloTEC_vx7.conf .. highlight:: bash .. literalinclude:: ../../../../parm/use_cases/model_applications/space_weather/GridStat_fcstGloTEC_obsGloTEC_vx7.conf .. GENERATED FROM PYTHON SOURCE LINES 106-121 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 123-151 Running METplus --------------- This use case can be run two ways: 1) Passing in GridStat_fcstGloTEC_obsGloTEC_vx7.conf then a user-specific system configuration file:: run_metplus.py -c /path/to/METplus/parm/use_cases/model_applications/space_weather/GridStat_fcstGloTEC_obsGloTEC_vx7.conf -c /path/to/user_system.conf 2) Modifying the configurations in parm/metplus_config, then passing in GridStat_fcstGloTEC_obsGloTEC_vx7.conf:: run_metplus.py -c /path/to/METplus/parm/use_cases/model_applications/space_weather/GridStat_fcstGloTEC_obsGloTEC_vx7.conf The former method is recommended. Whether you add them to a user-specific configuration file or modify the metplus_config files, the following variables must be set correctly: * **INPUT_BASE** - Path to directory where sample data tarballs are unpacked (See Datasets section to obtain tarballs). This is not required to run METplus, but it is required to run the examples in parm/use_cases * **OUTPUT_BASE** - Path where METplus output will be written. This must be in a location where you have write permissions * **MET_INSTALL_DIR** - Path to location where MET is installed locally Example User Configuration File:: [dir] INPUT_BASE = /path/to/sample/input/data OUTPUT_BASE = /path/to/output/dir MET_INSTALL_DIR = /path/to/met-X.Y **NOTE:** All of these items must be found under the [dir] section. .. GENERATED FROM PYTHON SOURCE LINES 153-168 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 space_weather/glotec_vs_glotec/output_data/2015_03_17 (relative to **OUTPUT_BASE**) and will contain the following files: * grid_stat_GloTEC_without_cosmic-vx7_TEC_vs_GloTEC_with_cosmic_000000L_20150317_000500V_pairs.nc * grid_stat_GloTEC_without_cosmic-vx7_TEC_vs_GloTEC_with_cosmic_000000L_20150317_001500V_pairs.nc * grid_stat_GloTEC_without_cosmic-vx7_TEC_vs_GloTEC_with_cosmic_000000L_20150317_000500V.stat * grid_stat_GloTEC_without_cosmic-vx7_TEC_vs_GloTEC_with_cosmic_000000L_20150317_001500V.stat ..
