has been conducted in the frame of the European Commission funded network of excellence ECATS, at Athens International Airport (AIA), Greece, from 13 to 25 September 2007. In order to quantify the background air quality and study the influence of meteorological conditions and airport emissions to the broader region, the analysis was extended to the greater Messogia Plain of Attica, Greece. Mixing height was estimated taking into account measurements from remote sensing and surface based single point instrumentation. According to the analysis, the air quality over Messogia Plain is mainly controlled by the intensity and the direction of the background flow. Under low background wind conditions, the development of local flows (sea and land breeze cells) over the greater area preserves high concentrations of air pollutants which are mainly attributed to the airport emissions, the local activities and traffic. When the background flow is strong, the diurnal cycle of all concentrations was significantly reduced by more than 50%, due to the advection and the subsequent mixing of the lower atmosphere. In order to identify and quantify the various processes linked with meteorology and air quality, the Hilbert-Huang transform was selected to be applied on the air-quality time-series data. The calculated Hilbert spectra of the main pollutants showed that meteorology plays a prescriptive role on the evolution of air pollutants, determining the influence of the local scale characteristics at each station. © 2011 Elsevier Ltd.</style></abstract><notes><style face="normal" font="default" size="100%">cited By (since 1996)2</style></notes></record></records></xml>
