""" EnsembleStat: Using Python Embedding for Aerosol Optical Depth ============================================================================= model_applications/air_quality_and_comp/EnsembleStat_fcstICAP_obsMODIS\ _aod.conf """ ############################################################################ # Scientific Objective # -------------------- # # To provide useful statistical information on the relationship between # observation data for aersol optical depth (AOD) to an ensemble forecast. # These values can be used to help correct ensemble member deviations from observed values. ############################################################################## # Datasets # -------- # # | **Forecast:** International Cooperative for Aerosol Prediction (ICAP) ensemble netCDF file, 7 members # | **Observation:** Aggregate netCDF file with MODIS observed AOD field # # | **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. # | # ############################################################################## # METplus Components # ------------------ # # This use case utilizes the METplus EnsembleStat wrapper to read in files using Python Embedding # ############################################################################## # METplus Workflow # ---------------- # # EnsembleStat is the only tool called in this example. It processes a single run time with seven ensemble members. Three of the members do not have data for the AOD field, so EnsembleStat will only process four of the members for statistics. # ############################################################################## # 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/air_quality_and_comp/EnsembleStat_fcstICAP_obsMODIS_aod.conf # # .. highlight:: bash # .. literalinclude:: ../../../../parm/use_cases/model_applications/air_quality_and_comp/EnsembleStat_fcstICAP_obsMODIS_aod.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!
