""" CycloneVerification: TC Verification Compare ADECK vs BDECK =========================================================== model_applications/tc_and_extra_tc/TCPairs_TCStat_fcstADECK_obsBDECK_ATCF_BasicExample.conf """ ########################################### # Scientific Objective # -------------------- # # This use case run TC-Pairs to produce produce matched pairs of forecast model # output and an observation dataset. TC-Pairs produces matched pairs for position # errors, as well as wind, sea level pressure, and distance to land values for # each input dataset. Then TC-stat will filter TC-pairs output based on user criteria. ############################################################################## # Datasets # -------- # # # | **Forecast:** Adeck # | /path/to/TCPairs_TCStat_fcstADECK_obsBDECK_ATCF_BasicExample/a{basin}{cyclone}{init?fmt=%Y}.dat # | **Observation:** Bdeck # | /path/to/{TCPairs_TCStat_fcstADECK_obsBDECK_ATCF_BasicExample/b{basin}{cyclone}{init?fmt=%Y}.dat # # | **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 # | The 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 # | ############################################################################## # METplus Workflow # ---------------- # # The following tools are used for each run time: # # TCPairs # TCStat # # To generate TCPairs output, this example loops by initialization time for every 6 hour period that is available # in the data set between 2021082500 and 2021083000. Then TCStat filters the TCPairs output based on user criteria # (e.g. storm characteristics in this use case). # ############################################################################## # METplus Components # ------------------ # # This use case first runs TC-Pairs to produce matched pairs of Adeck and Bdeck files. # The TC-Pairs output (tcst files) is then read by the TC-Stat tool to further filter the tcst files # as well as summarize the statistical information. ############################################################################## # METplus Workflow # ---------------- # # TCPairs is the first tool called in this example. It processes the following # run times for each storm file (e.g. aal092021.dat, aal102021.dat) against the corresponding # Bdeck files (e.g. bal092021.dat, bal102021.dat): # # | **Init/Valid:** 2021082500 # | **End/Valid:** 2021083000 # # TC-Stat is the second (and final) tool called in this example. It processes the output # from TCPairs. In this example the TC-Stat filters the TC-Pairs output based on the # characteristics of the storm (HU, SD, SS, TS, TD). The output from the TC-Stat can be used to # aggregate verification statistics (e.g. Track, Intensity, MSLP, wind radii errors etc.). # ############################################################################## # 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 /path/to/TCPairs_TCStat_fcstADECK_obsBDECK_ATCF_BasicExample.conf # # .. highlight:: bash # .. literalinclude:: ../../../../parm/use_cases/model_applications/tc_and_extra_tc/TCPairs_TCStat_fcstADECK_obsBDECK_ATCF_BasicExample.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!
