The # HRRR-Time Lag Ensemble (TLE) used in this example was used to demonstrate # prototype ensemble post-processing techniques. A time-lagged ensemble can # provide higher temporal resolution and be used to compute several different # accumulation amounts based on # what data is available for each run time. 6 hour and 1 hour observation data # is available at 6Z, so the 6 hour accumulation data is used. However, at 7Z # only a 1 hour accumulation field is available, so it uses the 1 hour field, # then steps back in time trying to build a 6 hour accumulation with earlier # data. METplus is configured to only allow 1 hour or 6 hour accumulations in # the input files, so a set of six 1 hour accumulation fields are combined to # create a 6 hour accumulation field. The result is compared to the 6 hour # forecast data. ############################################################################## # Version Added # ------------- # # METplus version 3.0 ############################################################################## # Datasets # -------- # # **Forecast:** NOAA High Resolution Rapid Refresh Time-Lagged Ensemble (HRRR-TLE) # probabilistic forecasts in GRIB2 # # **Observation:** Stage IV GRIB 1 and 6 hour precipitation accumulation # # **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. ############################################################################## # METplus Components # ------------------ # # This use case first runs PCPCombine on the observation data to build a 6 # hour precipitation accumulation from 1 hour files or a single 6 hour file. # Then the observation data is regridded to the model grid using the RegridDataPlane. Finally, the # observation files are compared to the forecast data using GridStat. ############################################################################## # METplus Workflow # ---------------- # # **Beginning time (INIT_BEG):** 2016090412 # # **End time (INIT_END):** 2016090412 # # **Increment between beginning and end times (INIT_INCREMENT):** 60 # # **Sequence of forecast leads to process (LEAD_SEQ):** 6, 7 # # The following tools are used for each run time: # # PCPCombine (observation) > RegridDataPlane (observation) > GridStat # # This example loops by initialization time. For each initialization time # it will process forecast leads 6 and 7. There is only one # initialization time in this example, so the following will be run: # # Run times: # # | **Init:** 2016-09-04_12Z # | **Forecast lead:** 6 # | # | **Init:** 2016-09-04_12Z # | **Forecast lead:** 7 ############################################################################## # 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/precipitation/GridStat_fcstHRRR-TLE_obsStgIV_GRIB.conf # # .. highlight:: bash # .. literalinclude:: ../../../../parm/use_cases/model_applications/precipitation/GridStat_fcstHRRR-TLE_obsStgIV_GRIB.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!
