If in the exp-config.h file the OIFS_PPROC variable has been set to true (or if the --pproc command line parameter was used) then the model output in the experiment directory is further processed after completing the model run.

  • In this case the script will generate a folder called  output_YYYMMDD_HHMMSS , with YYYYMMDD being the current date and HHMMSS the current time. 
  • This avoids accidental modification or overwriting of any previous results when the model experiment is repeated.
  • The variable OUTPUT_ROOT in exp-config.h determines where this ouput folder will be created. The default location is inside the experiment directory, but when assigning another path to OUTPUT_ROOT this could be created elsewhere.

The postprocessing groups all model output fields and diagnostics into individual GRIB files with ascending forecast time step. Also, a copy of the atmospheric model namelist file fort.4, as well as the ifs.stat and NODE.01_001 log files are moved into the output folder.
