This benchmark comprises the latter 3 hours of a 6-hour, 2.5km resolution case covering the Continental U.S. (CONUS) domain June 4, 2005, using the Eulerian Mass (EM) dynamics with a 15 second time step. The benchmark period is hours 3-6 (3 hours), starting either from initial conditions (for a 6 hour run) or from a restart file that begins at the end of the initial 3 hour period (for a restart). Since model output at the end of 6 hours is the same either way, it is the benchmarker's choice.
The recommended benchmark code is WRF version 2.1.1 (click here) .
This page contains links to a README file, the basic input files for the benchmark (relatively small), and large input files: (1) the lateral boundary condition file wrfbdy_d01 and (2) either the initial conditions file, wrfinput_d01 (for 6 hour cold start), or the restart file wrfrst_d01_2005-06-04_03:00:00 (for 3 hour restart).
Note that the large benchmark input files are provided unformatted Fortran binary output (big-endian) and the namelist files provided with this benchmark are set to read this format (io_form_* variables = 1). WRF output for this benchmark is also in this binary format. The compile configuration options distributed with WRF are already set to read big-endian binary on all little-endian machines to which WRF is currently ported.
These are the benchmark README file plus the namelist.input files for either a 6 hour code start or a 3 hour restart, and other files that need to be in the directory where WRF is run. This also contains sample stderr and stdout from a benchmark run (3hr restart) and a file containing sample output comparison statistics.
