This one time, at band camp, we tried to run the WRF model. It was so funny.
Real-time WRF User Support
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).

The Meteorological Input Data
You need to have the wrf_input.d01.YYYY-wrf_input.d01.YYYY-MM-DD_hh:mm:ssMM-DD_hh:mm:ss and the wrf_input.global_datawrf_input.global_data
files available from the WRF SI program (linked into the ./WRFV1/test/eh_real./WRFV1/test/eh_real directory is adequate)
These files, one for each time period, are input to the program real.exereal.exe
Running real.exe and wrf.exeIn the ./WRFV1/test/eh_real./WRFV1/test/eh_real directory,
./real.exe./real.exe
And then if you have the following files output from the program real.exereal.exe: wrfinput, wrfinput, wrfbdywrfbdy
Then, you get to run: ./wrf.exe./wrf.exe
