Impact of road traffic emissions on air quality of the Lisbon region

摘要: The main purpose of this paper is to present the study traffic emissions impact on Lisbon region air quality. Two approaches emission data generation with high spatial and temporal resolution are presented compared. Main roads were processed as line sources hot on-road calculated based daily mean factors distinguished for several road classes vehicle types. Also, disaggregation national CORINAIR inventory has been performed basis statistical information fuel consumption population density. comparison obtained by these two demonstrates a good agreement total values, but significant difference distribution data. To ensure completeness data, improve their also analyse emissions, combination was applied generate used photochemical numerical system simulate atmospheric circulation pollution pattern in under summer meteorological conditions, having different scenarios. It possible conclude that an abatement strategy urgently needed it should take into account strong contribution levels.
