GENERATED FROM PYTHON SOURCE LINES 9-16 Scientific Objective -------------------- Converting file formats so data can be read by the MET tools. This use case demonstrates the ability to utilize two python embedding script calls to generate multiple fields in a single output file. .. GENERATED FROM PYTHON SOURCE LINES 18-26 Datasets -------- | **Inputs:** Canned ASCII data to test functionality | **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 28-32 METplus Components ------------------ This use case utilizes the METplus PyEmbedIngest wrapper to generate a command to run the MET tool RegridDataPlane if all required files are found. .. GENERATED FROM PYTHON SOURCE LINES 34-39 METplus Workflow ---------------- PyEmbedIngest is the only tool called in this example. It has one run time, but the time is not relevant because the files processed do not have any time information in the names. .. GENERATED FROM PYTHON SOURCE LINES 41-50 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/PyEmbedIngest/PyEmbedIngest_multi_field_one_file.conf .. highlight:: bash .. literalinclude:: ../../../../parm/use_cases/met_tool_wrapper/PyEmbedIngest/PyEmbedIngest_multi_field_one_file.conf .. GENERATED FROM PYTHON SOURCE LINES 52-57 MET Configuration ----------------- None. RegridDataPlane does not use configuration files. .. GENERATED FROM PYTHON SOURCE LINES 59-66 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 68-96 Running METplus --------------- This use case can be run two ways: 1) Passing in PyEmbedIngest_multi_field_one_file.conf then a user-specific system configuration file:: run_metplus.py -c /path/to/METplus/parm/use_cases/met_tool_wrapper/PyEmbedIngest/PyEmbedIngest_multi_field_one_file.conf -c /path/to/user_system.conf 2) Modifying the configurations in parm/metplus_config, then passing in PyEmbedIngest_multi_field_one_file.conf:: run_metplus.py -c /path/to/METplus/parm/use_cases/met_tool_wrapper/PyEmbedIngest/PyEmbedIngest_multi_field_one_file.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 98-112 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/PyEmbedIngest (relative to **OUTPUT_BASE**) and will contain the following file: * test.nc * regrid_data_plane.nc ..
