Run real.exe for 2 domains:   STEP 3

• Make sure you are in the WRFV3/test/em_real directory
   
   
• Edit your namelist.input file to make sure columns 1 and 2 are set up to run for 2 domains. Pay specific attention to:
   
  

  run_hours = 24,
  start_year
  start_month
  start_day
  start_hour
  end_year
  end_month
  end_day
  end_hour
  interval_seconds
  max_dom
  e_we
  e_sn
  dx
  dy
   
  

   NOTE:
  • Set interval_seconds to the same value used when running your coarse domain case.
  • Set e_we, e_sn, dx, and dy for BOTH domains.
  • Make sure max_dom is set to 2
     
     
• Link met_em data from WPS:
   
       ln -sf ../../../WPS/met_em.* .
   
   
   
• Run real.exe
   
       This will generate a wrfinput_d01 file, a wrfinput_d02 file, and a wrfbdy_d01 file.
  
       RENAME the wrfinput_d02 file:
   
          mv wrfinput_d02 wrfndi_d02
