  1. Initialization. III: Real Data initialization Dave Gill gill@ucar.edu http://wrf-model.org

  2. This one time, at band camp, we tried to run the WRF model. It was so funny.

  3. Real-time WRF User Support

  4. Assuming I have the SI data, what next? The WRF model requires additional processing on the SI data before it can be input. The input variables are used for additional diagnostics, balancing, and coupling. This is handled in the pre-processor program real.exe. Currently, this program ONLY runs on a single processor. The real.exe program outputs data in a format similar to the WRF model (wrfinput and wrfbdy).

  5. How to build eh real.exe and wrf.exe • Get the WRFV1 tar file • unzip and untar the file • cd ./WRFV1 • configure • compile eh_real • cd ./test/eh_real • vi namelist.input

  6. What to modify in the ./test/eh_real namelist.input &namelist_01 time_step_max &namelist_02 s_we , s_sn , s_vert e_we , e_sn , e_vert &namelist_03 ztop dx = dy dt You get help You get help if you mess these up

  7. eh_real namelist.input, #2 &namelist_04 specified &namelist_05 start_year , start_month , start_day , start_hour end_year , end_month , end_day , end_hour interval real_data_init_type Panic oriented help

  8. The Entire namelist.input file ./test/eh_real/namelist.input

  9. The Meteorological Input Data You need to have the wrf_input.d01.YYYY-MM-DD_hh:mm:ss and the wrf_input.global_data files available from the WRF SI program (linked into the ./WRFV1/test/eh_real directory is adequate) These files, one for each time period, are input to the program real.exe

  10. Running real.exe and wrf.exe In the ./WRFV1/test/eh_real directory, ./real.exe And then if you have the following files output from the program real.exe:wrfinput, wrfbdy Then, you get to run: ./wrf.exe
