GENERATED FROM PYTHON SOURCE LINES 10-14 Scientific Objective -------------------- None. Simply regridding data to match a desired grid domain for comparisons. .. GENERATED FROM PYTHON SOURCE LINES 16-24 Datasets -------- | **Forecast:** ASCII sample file | **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 26-30 METplus Components ------------------ This use case utilizes the METplus RegridDataPlane wrapper to generate a command to run the MET tool RegridDataPlane if all required files are found. .. GENERATED FROM PYTHON SOURCE LINES 32-41 METplus Workflow ---------------- RegridDataPlane is the only tool called in this example. It processes a single run time, but the data does not contain any time information in the filename, so the run time is irrelevant. This use case regrids data to another domain specified with REGRID_DATA_PLANE_VERIF_GRID. This is done so that forecast and observation comparisons are done on the same grid. Many MET comparison tools have regridding capabilities built in. However, if the same file is read for comparisons multiple times, it is redundant to regrid that file each time. Running RegridDataPlane allows you to regrid once and use the output in many comparisons/evaluations. .. GENERATED FROM PYTHON SOURCE LINES 43-52 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/met_tool_wrapper/RegridDataPlane/RegridDataPlane_python_embedding.conf .. highlight:: bash .. literalinclude:: ../../../../parm/use_cases/met_tool_wrapper/RegridDataPlane/RegridDataPlane_python_embedding.conf .. GENERATED FROM PYTHON SOURCE LINES 54-59 MET Configuration ----------------- None. RegridDataPlane does not use configuration files. .. GENERATED FROM PYTHON SOURCE LINES 61-68 Python Embedding ---------------- This use case calls a Python script to read the input data. The Python script is stored in the MET repository: /path/to/MET/installation/share/met/python/read_ascii_numpy.py `read_ascii_numpy.py `_ .. GENERATED FROM PYTHON SOURCE LINES 70-98 Running METplus --------------- This use case can be run two ways: 1) Passing in RegridDataPlane_python_embedding.conf then a user-specific system configuration file:: run_metplus.py -c /path/to/METplus/parm/use_cases/met_tool_wrapper/RegridDataPlane/RegridDataPlane_python_embedding.conf -c /path/to/user_system.conf 2) Modifying the configurations in parm/metplus_config, then passing in RegridDataPlane_python_embedding.conf:: run_metplus.py -c /path/to/METplus/parm/use_cases/met_tool_wrapper/RegridDataPlane/RegridDataPlane_python_embedding.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 100-112 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 met_tool_wrapper/RegridDataPlane/regrid_py (relative to **OUTPUT_BASE**) and will contain the following file: * numpy_data.nc ..
