Summary

The combined UAM-AERO/RAMS modeling system has been applied to study the dynamicsof photochemical gaseous species and particulate matter processes in the eastern Mediterraneanarea between the Greek mainland and the island of Crete. In particular, the modeling systemis applied to simulate atmospheric conditions for two periods, i.e., 13–16 July 2000 and 26–30July 2000. The spatial and temporal distributions of both gaseous and particulate matter pollutantshave been extensively studied together with the identification of major emission sources in the area.New pre-processors were developed for the UAM-AERO model for evaluating detailed emissioninventories for biogenic compounds, resuspended dust and sea salt. Comparison of the modelingresults with measured data was performed and satisfactory agreement was found for a number ofgaseous species. However, the model underestimates the PM10 measured concentrations during summer.This is mainly due to the considerable underestimation of particulate matter emissions and inparticular dust resuspension, the effect of forest fire emissions and the contribution of Saharan dustepisodes.
