Abstract

During an air pollution episode the ambient pollutant concentrations are exceptionally high. The latest severe episode in Finland prevailed in December 1995. The measured NO2 and CO concentrations in Helsinki increased to a high level, even by international standards. As a result of this incident and alterations in legislation, a joint research project was started between VTT Communities and Infrastructure and the Finnish Meteorological Institute. The project investigated the meteorological factors leading to air quality episodes, the possibilities for their forecasting, the urban air quality in Finland, the exhaust emissions from road traffic, and the conceivable measures for controlling traffic during an episode. The project also included a journey to three European cities which already have existing emergency plans in case of air pollution episodes.
