MESOSCALE TRANSPORT OF AIR-POLLUTANTS OVER ATHENS - IMPLICATIONS FOR AIR-QUALITY

Air pollutants released from sources located near and around extensive conurbations such as the Athens Metropolitan Area, can be transported over them under various atmospheric conditions. Some of the industria l sources located to the north-east of Athens are directly responsible for the transport and dispersion of a large number of pollutants. In this paper the result of a number of simulations using an atmospheric and a Lagrangian particle dispersion model for the north-easterly wind -flow case is presented. These simulations strongly indicate that poll utants are transported from Central Evia to the Athens area under cert ain conditions.
