""" MODEMultivar: Create objects of brightness temps and radar reflectivity ======================================================================= model_applications/short_range/MODEMultivar_fcstRRFS_obsGOES_MRMS_BrightnessTemp_Lightning.conf """ ############################################################################## # .. contents:: # :depth: 1 # :local: # :backlinks: none ############################################################################## # Scientific Objective # -------------------- # # This use case identifies convective objects, which are defined by # the intersection of: 1) satellite infrared brightness temperature < 235 K and # 2) radar reflectivity > 40 dBZ. # Satellite brightness temperatures are used in conjunction with radar reflectivity # to capture both the cloud top (satellite) and in-cloud (radar) characteristics. # Convective objects are also defined as lightning thresholds exceeding the 10th percentile. # A percentile threshold is used for lightning data as RRFS lightning has units # which are “non-dimensional” and therefore cannot be directly compared to the # Geostationary Lightning Mapper. ############################################################################## # Version Added # ------------- # # METplus Version 6.0 ############################################################################## # Datasets # -------- # # **Forecast:** Rapid Refresh Forecast System (RRFS) 3km resolution, # channel 13 brightness temperature, # composite reflectivity, and lightning strike density. # # **Observation:** Geostationary Operational Environmental Satellites (GOES) 3km resolution, # channel 13 brightness temperature; # Multi-radar Multi-sensor (MRMS) 3km resolution, composite reflectivity; # GOES Global Lightning Mapper (GLM) 3km resolution, flash_extent_density. # # **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` for more information. ############################################################################## # METplus Components # ------------------ # # The only tool this use case calls is MODE, which will identify super-objects # by intersection of the multiple variable fields. ############################################################################## # METplus Workflow # ---------------- # # **Beginning Time (INIT_BEG):** 2024010905 # # **End Time (INIT_END):** 2024010905 # # **Increment between beginning and end times (VALID_INCREMENT):** 1H # # **Sequence of forecast leads to process (LEAD_SEQ):** 9,10 # # This use case runs twice, once for each forecast lead time provided. It # creates objects valid at 14UTC and 15UTC from 09 January 2024 are compared to # the 9h and 10h forecasts initialized at 05UTC on 9 January 2024. # Convective objects are identified with thresholds of # satellite brightness temperature < 235 K and radar reflectivity > 40 dBZ, # or lightning > 10th percentile. # In this use case, MODE super-object intensity statistics are output for both # radar reflectivity and lightning. Using the MODE_MULTIVAR_INTENSITY_FLAG, # users can control for which variables super object intensity statistics will be output. # If all are set to False, then no intensity information will be output # and only statistics relative to the super-object geometry will be available. ############################################################################## # 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/short_range/MODEMultivar_fcstRRFS_obsGOES_MRMS_BrightnessTemp_Lightning.conf # # .. highlight:: bash # .. literalinclude:: ../../../../parm/use_cases/model_applications/short_range/MODEMultivar_fcstRRFS_obsGOES_MRMS_BrightnessTemp_Lightning.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!
