""" PointStat: Python embedding to read Argo netCDF files to verify ocean temperature forecast at 50 m depth ======================================================================================================== model_applications/marine_and_cryosphere/PointStat_fcstRTOFS_obsARGO_climoWOA23_temp.conf """ ############################################################################## # .. contents:: # :depth: 1 # :local: # :backlinks: none ############################################################################## # Scientific Objective # -------------------- # # This use case utilizes the ASCII2NC tool with python embedding to natively read in Argo # netCDF files, a common source of ocean profile data for operational entities. These # values are then used by the PointStat tool to verify RTOFS ocean temperature forecast at 50 m depth. ############################################################################## # Version Added # ------------- # # METplus version 5.1 ############################################################################## # Datasets # -------- # # **Forecast:** NOAA Global Real-Time Ocean Forecast System (RTOFS) v2.3 forecast # data pre-processed into 0.1 degree lat-lon grid # # **Observations:** Argo free drifting profiling floats # # **Climatology:** World Ocean Atlas 2023 (WOA23) # # **Sea Ice Mask:** Mask file to exclude forecast grid points with sea ice concentration > 15% # # **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 calls ASCII2NC to read in Argo netCDF files and then PointStat for # verification against RTOFS model data. ############################################################################## # METplus Workflow # ---------------- # # **Beginning time (VALID_BEG):** 20230318 # # **End time (VALID_END):** 20230318 # # **Increment between beginning and end times (VALID_INCREMENT):** 24H # # **Sequence of forecast leads to process (LEAD_SEQ):** 024 # # ASCII2NC is the first tool called. It pulls in three Argo files for the Atlantic, # Pacific, and Indian Oceans, respectively using a Python script. These observations are converted into a netCDF # file, which is then called by PointStat as the observation dataset. PointStat also pulls # in a forecast from the RTOFS for ocean temperature at 50 m depth, which is included in # the range of available observation times, and two monthly climatology files from the # WOA23 to calculate daily climatology for the valid date. A 24-hour (18Z to 18Z) window is # allowed for the observational data, and a “UNIQUE” flag is set to only use the # observational data closest to the forecast valid time at a given location. Temperature # thresholds are set to correspond to operational usage, and the CTC, CTS, CNT, SL1L2, and # SAL1L2 line types are requested. # It processes the following run time: # # **Valid:** 2023-03-18 00Z # # **Forecast lead:** 24 hour ############################################################################## # METplus Configuration # --------------------- # # METplus first loads all of the default 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/marine_and_cryosphere/PointStat_fcstRTOFS_obsARGO_climoWOA23_temp.conf # # .. highlight:: bash # .. literalinclude:: ../../../../parm/use_cases/model_applications/marine_and_cryosphere/PointStat_fcstRTOFS_obsARGO_climoWOA23_temp.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!
