Abstract

Satellite images show that WRF/CHEM model has simulated emission, source, diffusion as well as the extent of the areas covered with dust very well.  Comparing PM10 concentration of the model outputs with Environment Organization data, show that WRF/CHEM model forecast daily changes very well. But model underestimate significantly in quantity of concentration. These errors may be are due to a model considering only dust quantity but other pollutants have affects on visibility. EURAD model has wrong prediction in dust storm sources and it simulates it in central of our country. In general, it can be said that in this event, dust concentration has been underestimated by WRF/CHEM model especially in maximum amount of PM10 concentration and EURAD model does not simulate dust concentration correctly in amounts and dispersion patterns.
