Benchmark Cases

Benchmark cases are available for WRFv4.4 and WRFv4.2.2.


WRFv4.4

Files for benchmarking are created with WPSV4.4 and WRFV4.4 (but can be used with any V4* WRF code).

  • Input data : GFS 0.25 degree analysis

  • The case used for the CONUS tests is the Pre-Thanksgiving Winter Storm of 2019.

  • The full test (original wrf simulation, and then restart) was completed with both an ifort and gnu build of WRF.

  • The tar files listed below contain the following data and scripts for benchmarking purposes:

    • namelist.input (x2) - set up to run a full WRF simulation, and then a 1 hour restart, as well as the namelist.wps for each case

    • wrfbdy_d01 and wrfinput_d0* - Boundary and initial conditions created by the real program

    • A batch script used to run wrf for the original simulation and the restart simulation

    • *.dat files - data files required for Thompson microphysics (these are usually generated during WRF, but take a while to produce)

    • diffwrf.py - script to compare the wrfout file generated by the initial simulation with the wrfout file generated by the restart simulation

    • *.png files - sample PNG files of acceptable differences

    • README - A text file including details about the cases and instructions for running the test and verifying results

    • wrfout* and wrfrst* files - history and restart files created during the tests - can be used for comparison

    • rsl.out.000* files - simulation log files for the original WRF simulation and restarts
