The project will study excess aerosol episodes (dust storms and pollution) that occur over Cairo and other cities in the region.  Trends in water vapor content confirm that aerosol contributes to possible local climate change. The plan is to use various aerosol-related parameters derived from satellite data over a long period coupled with linear genetic programming (LGP) technology for better understanding of the effects of different air pollution episodes over Cairo. This will provide insight into the microphysics of the air dynamics and enhance the understanding of the role of different atmospheric parameters under investigation. The results can be used for the identification and control of pollution sources to provide first-hand corrective actions, proper management and policy recommendations.  This project will initiate further collaboration between Chapman University and other research institutes and centers internationally.
