GENERATED FROM PYTHON SOURCE LINES 9-13 .. contents:: :depth: 1 :local: :backlinks: none .. GENERATED FROM PYTHON SOURCE LINES 15-20 Scientific Objective -------------------- This use case utilizes the new ASCII2NC method to natively read in NDBC ASCII files, a common source of sea surface data for operational entities. These values are then compared to GFS' new wave height output, which it incorporated from Wave Watch III. .. GENERATED FROM PYTHON SOURCE LINES 22-26 Version Added ------------- METplus version 5.1 .. GENERATED FROM PYTHON SOURCE LINES 28-45 Datasets -------- **Forecast:** NOAA Global Forecast System (GFS) v16 forecast data from WAVE file category **Observations:** ASCII buoy files from NOAA National Data Buoy Center (NDBC) **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 47-52 METplus Components ------------------ This use case calls ASCII2NC to read in ASCII buoy files and then PointStat for verification against GFS model data. .. GENERATED FROM PYTHON SOURCE LINES 54-73 METplus Workflow ---------------- **Beginning time (VALID_BEG):** 2022101609 **End time (VALID_END):** 2022101609 **Increment between beginning and end times (VALID_INCREMENT):** 1M **Sequence of forecast leads to process (LEAD_SEQ):** 0 ASCII2NC is the first tool called. It pulls in all files with a .txt type, which is the ASCII buoy data saved format. These observations are converted into a netCDF, which is then called by PointStat as the observation dataset. PointStat also pulls in a 3 hour forecast from the GFS for wave heights, which is included in the range of available buoy observation times. A +/- 30 minute window is allowed for the observational data. Thresholds are set that correspond to operational usage, and the CTC and CTS line types are requested. It processes the following run time: **Valid:** 2022-10-16 09Z .. GENERATED FROM PYTHON SOURCE LINES 75-84 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/marine_and_cryosphere/PointStat_fcstGFS_obsNDBC_WaveHeight.conf .. highlight:: bash .. literalinclude:: ../../../../parm/use_cases/model_applications/marine_and_cryosphere/PointStat_fcstGFS_obsNDBC_WaveHeight.conf .. GENERATED FROM PYTHON SOURCE LINES 86-104 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:: Ascii2NcConfig_wrapped .. literalinclude:: ../../../../parm/met_config/Ascii2NcConfig_wrapped .. dropdown:: PointStatConfig_wrapped .. literalinclude:: ../../../../parm/met_config/PointStatConfig_wrapped ..

GENERATED FROM PYTHON SOURCE LINES 112-116 User Scripting -------------- User Scripting is not used in this use case. .. GENERATED FROM PYTHON SOURCE LINES 118-127 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/marine_and_cryosphere/PointStat_fcstGFS_obsNDBC_WaveHeight.conf /path/to/user_system.conf See :ref:`running-metplus` for more information. .. GENERATED FROM PYTHON SOURCE LINES 129-144 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 PointStat and buoy_ASCII directories (relative to **OUTPUT_BASE**) and will contain the following files: * point_stat_030000L_20221016_090000V_ctc.txt * point_stat_030000L_20221016_090000V_cts.txt * point_stat_030000L_20221016_090000V.stat * buoy_2022101609.nc ..
