""" GridStat: Cloud Height with Neighborhood and Probabilities ========================================================== model_applications/clouds/GridStat_fcstMPAS_obsERA5_cloudBaseHgt.conf """ ############################################################################## # Scientific Objective # -------------------- # # This use case captures various statistical measures of two model comparisons # for cloud base height with different neighborhood settings for internal # model metrics and to aid in future model updates # ############################################################################## # Datasets # -------- # # | **Forecast:** Model for Prediction Across Scales (MPAS) # | **Observations:** ECMWF Reanalysis, Version 5 (ERA5) # | **Grid:** GPP 17km masking region # # | **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 # | This 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 Python Embedding, which is called using the PYTHON_NUMPY keyword # in the forecast and observation input template settings. The same Python script processes both forecast and # observation datasets. The forecast field is verified against the respective observation field, # with the Python script being passed the input file, the model name, the variable name being analyzed, # the initialization and valid times, and a flag to indicate if the field passed is observation or forecast. # This process is repeated with 2 instance names to GridStat, each with a different setting for regridding, # neighborhood evaluation, thresholding, output line types, and output prefix names. ############################################################################## # METplus Workflow # ---------------- # # GridStat is the only MET tool called in this example. # It processes the following run time: # # | **Init:** 2020-07-23 00Z # | **Forecast lead:** 36 hour # # Because instance names are used, GridStat will run 2 times for this 1 initalization time. ############################################################################## # METplus Configuration # --------------------- # # METplus first loads the default configuration file found in parm/metplus_config, # then it loads any configuration files passed to METplus via the command line: # parm/use_cases/model_applications/clouds/GridStat_fcstMPAS_obsERA5_cloudBaseHgt.conf # # .. highlight:: bash # .. literalinclude:: ../../../../parm/use_cases/model_applications/clouds/GridStat_fcstMPAS_obsERA5_cloudBaseHgt.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!
