""" Grid-Stat, Stat-Analysis, Data-Ingest: CREDIT and GFS statistics and Data Download ================================================================================== model_applications/medium_range/GridStat_fcstCREDIT_GFS_obsGFS_6hrRealtime.conf """ ############################################################################## # .. contents:: # :depth: 1 # :local: # :backlinks: none ############################################################################## # Scientific Objective # -------------------- # # This use case is an example for verification within RAL to illustrate how to # compare two models and also how to download data automatically. The use case was # originally designed to be run in real-time using the now keyword in VALID_BEG and # VALID_END. However, a specified date is used in this example for our automated # testing. The case demonstrates how to run statistics comparing two models, # NSF NCAR Community Research Earth Digital Intelligence Twin (CREDIT) and GFS # for both the surface and upper air evaluation. Surface and upper air # statistics are run separately since they are stored in separate observation files. ############################################################################## # Version Added # ------------- # # METplus version 6.2 ############################################################################## # Datasets # -------- # # **Forecast**: CREDIT ~0.28 degree model and GFS 0.25 degree model # # **Observation**: GFS Analysis # # **Climatology:** None # # **Location:** The CREDIT model 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. # # The GFS model data and GDAS observations are downloaded automatically. Make sure you # have an internet connection. ############################################################################## # METplus Components # ------------------ # # This use case calls DataIngest once, GridStat 4 times and StatAnalysis once. GridStat # has 4 calls, 2 for the CREDIT model and 2 for the GFS using surface and upper air # observations respectively. ############################################################################## # METplus Workflow # ---------------- # # **Beginning time (VALID_BEG):** 2025-09-24 00Z # # **End time (VALID_END):** 2025-09-24 06Z # # **Increment between beginning and end times (VALID_INCREMENT):** 6 hours # # **Sequence of forecast leads to process (LEAD_SEQ):** 6, 12 # # The DataIngest and GridStat tools are run for each time, whereas StatAnalysis is # run once.

There will # be 3 directories, data_ingest which contains the downloaded data, grid_stat which contains the output # statistics, and StatAnalysis which contains the aggregated statistics. The data_ingest directory # will contain 2 subdirectories, GFS and GFS_analysis, each with the downloaded data. The data inside # the GFS directory is sorted by model initialization time and contains both surface and upper air data. # These files have the format, where II is the model initialzation hours and HHH is the lead time in # hours: # # * gfs.tIIz.pgrb2.0p25.fHHH # * gfs.tIIz.sfluxgrbfHHH.grib2 # # The GFS_analysis directory contains one subdirectory 20250924 with 4 files: # # * gfs.2025092400.pgrb2.0p25.anl # * gfs.2025092406.pgrb2.0p25.anl # * gfs_anal_2025092400.sfcanl.nc # * gfs_anal_2025092406.sfcanl.nc # # Inside the grid_stat directory, there are also 2 subdirectories, CREDIT/6h and GFS.
