""" TCGen: 2021 Global Forecast System (GFS) Tropical Cyclone Genesis Forecast =========================================================================== model_applications/tc_and_extra_tc/TCGen_fcstGFS_obsBDECK_2021season.conf """ ############################################################################## # .. contents:: # :depth: 1 # :local: # :backlinks: none ############################################################################## # Scientific Objective # -------------------- # # This use case runs TC-Gen to analyze the operational Global Forecast System (GFS) tropical cyclone (TC) genesis forecasts for a portion of the 2021 Atlantic and # Eastern Pacific basin hurrican seasons. TC-Gen will produce verification of deterministic and probabilistic tropical cyclone genesis forecasts in the ATCF # file and shape file formats. TC-Gen will output deterministic and probabilistic categorical counts and statistics and genesis matched pairs, which is a specific # line type for TC-Gen. ############################################################################## # Version Added # ------------- # # METplus version 4.1 ############################################################################## # Datasets # -------- # # | **Forecast:** GFS genesis file, GFS E Deck # | **Observation:** B Deck, A Deck # | **Warning Areas:** Shapefiles # # | **Location:** All of the input data required for this use case can be found in the tc_and_extra_tc 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. # | # | **Data Source:** NHC ftp.noaa.gov/atcf # | **Data Source:** www.nhc.noaa.gov/archive/wgtwo/ # | ############################################################################## # METplus Components # ------------------ # # This case utilizes the METplus TC-Gen wrapper to run TC-Gen for deterministic # and probabilistic genesis forecasts with ASCII and netcdf output. ############################################################################## # METplus Workflow # ---------------- # # TC-Gen is the only tool called in this example. It processes the following # run times: # # | **Init:** 2021-05-07 00 UTC - 2021-11-13 12 UTC # | **Forecast lead:** 06 - 120 hours # | ############################################################################## # 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/tc_and_extra_tc/TCGen_fcstGFS_obsBDECK_2021season.conf # # .. highlight:: bash # .. literalinclude:: ../../../../parm/use_cases/model_applications/tc_and_extra_tc/TCGen_fcstGFS_obsBDECK_2021season.conf ############################################################################## # 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:`TC-Gen 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/TCGenConfig_wrapped ############################################################################## # Running METplus # --------------- # # This use case can be run two ways: # # 1) Passing in the use case configuration file then a user-specific system configuration file:: # # run_metplus.py -c /path/to/METplus/parm/model_applications/tc_and_extra_tc/TCGen_fcstGFS_obsBDECK_2021season.conf -c /path/to/user_system.conf # # 2) Modifying the configurations in parm/metplus_config, then passing in use case configuration file:: # # run_metplus.py -c /path/to/METplus/parm/use_cases/model_applications/tc_and_extra_tc/TCGen_fcstGFS_obsBDECK_2021season.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. # ############################################################################## # 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/tc_and_extra_tc/TCGen (relative to **OUTPUT_BASE**) # and will contain the following files: # # * tc_gen.stat # * tc_gen_pstd.txt # * tc_gen_prc.txt # * tc_gen_pjc.txt # * tc_gen_pct.txt # * tc_gen_cts.txt # * tc_gen_ctc.txt # * tc_gen_genmpr.txt # * tc_gen_pairs.nc # ############################################################################## # Keywords # -------- # # .. note:: # # * TCGenToolUseCase # * TropicalCycloneUseCase # # Navigate to the :ref:`quick-search` page to discover other similar use cases. # # # # sphinx_gallery_thumbnail_path = '_static/tc_and_extra_tc-TCGen_fcstGFS_obsBDECK_2021season.png'
