Air quality and composition
Man-made and natural pollutants in the air we breathe affect our health and can influence the weather.
Pollutants such as sulphur dioxide, nitrogen oxides and particulate matter are released into the atmosphere as a result of the combustion of fossil fuels and industrial processes. Chemical interactions amongst these primary pollutants, under the influence of heat and solar radiation, can give rise to additional secondary pollutants. The build-up of these pollutants in the atmosphere is strongly influenced by meteorology. The pollutants can also influence meteorology in a feedback process. In order to predict atmospheric concentrations of pollutants we integrate knowledge of pollutant emissions with meteorology and chemical evolution in a forecast model.
