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 A1B and A1Fi scenarios (IPCC AR4 scenarios) but I can't find the data. I would appreciate it if you could help me to find proper data.
We don't archive any IPCC data. Please take a look at this document and see whether you can find helpful information.
You may contact people in NCAR CGD to ask more details about the data.
