How can I find data from a global climate simulation based on IPCC AR4 scenarios?

I am trying to run WRF-CMAQ simulation to predict concentration of PM2.5 in Middle East domain. For WRF simulation, I need 6 hours raw Grib data from a global climate model run based on IPCC AR4 scenarios but I can't find the data. I would appreciate it if you could help me to find proper data.

IPCC AR4 data are very old at this point and have been superseded. No data from any GCM are in grib format.

Do you really need data from AR4 or will other 6-hourly data do?

Thank you for your responses, I'm now pretty sure that I can't find any data from IPCC AR4 scenario runs, so I decided to use data from IPCC AR5 scenario runs. The data is needed for WRF model simulation so it must be in grib1 or grib2 format, other formats which could be converted to this formats should be ok.

There are any number of tools that can convert from netCDF to grib. The WRF support list/forum almost certainly has a list.
