Instructions for downloading restart and reference output for 2.5km V3 benchmark. Created July 8, 2008. Thanks to Andy Vogelmann at Brookhaven National Laboratory for generating the restarts and reference outputs on NYBlue, BNL's 18K node BG/L. --- 1. Data for doing the run (restart dataset, boundary file, and namelist) The restart data is in the 1-RST/RST subdirectory divided over 34 256KB files named rst_6hr* a. Download these. If your system has the wget utility: wget http://www.mmm.ucar.edu/WG2bench/conus_2.5_v3/1-RST/RST/files foreach f ( `cat files` ) echo $f wget http://www.mmm.ucar.edu/WG2bench/conus_2.5_v3/1-RST/RST/$f end Otherwise, right click each link to download the rst_6hr* files (lucky you). b After downloading, concatenate and unzip cat rst_6hr* | gunzip -c > wrfrst_d01_2005-06-04_06_00_00 c. Also download the namelist file 2-9HR/namelist.input. Note, the io_form_* settings in the time_control section of the namelist are currently set to 11, for paralel NetCDF (http://trac.mcs.anl.gov/projects/parallel-netcdf). If you prefer to use regular NetCDF change these settings from 11 to 2. (20090922 JM) d. Also download the boundary file, wrfbdy_d01.gz from this directory and then: gunzip wrfbdy_d01.gz e. Move or copy the restart, wrfbdy_d01, and namelist files to your run directory and run WRF 2. Validating your output against reference dataset The reference output is in the 2-9HR/9HR directory divided over 9 256KB files naed out_9hr* a. Download these and then: cat out_9hr* | gunzip -c > wrf_reference b. Run diffwrf to compare your history file with this one: /external/io_netcdf/diffwrf wrf_reference wrfout_2005-06-04_09_00_00 c. send the diffwrf output for this case when submitting your benchmark results (see benchmark instructions). Sample diffwrf output that was generated by comparing the wrf_reference data with wrfout file produced from a perturbed but otherwise identical run is included in this directory in the file diffout_reference_2.5km_v3. Perturbation was done by setting the pertub_input flag to true in the namelist.input file (see 3-9PERTURB subdirectory). DO NOT use this flag for your benchmark runs.
