Anthropogenic-Biogenic interactions

In the natural atmosphere, anthropogenic and biogenic sources of pollutants do not exist in isolation, and the potential interaction between the two pollutant sources has raised particular scientific interest.  Comprehensive study of the interactions between anthropogenic and biogenic emissions is a necessity for acquiring the better understanding of atmospheric composition and climate change. To investigate the interactions we have developed a unique research environment ILMARI, a top-class laboratory facility allowing the utilization of vehicle and biomass combustion emissions and VOC emissions from real plants in our experimental SOA studies. Our research focuses to explore the impact of anthropogenic emissions on biogenic SOA formation and its climate-relevant characteristics.
