Atmospheric Chemistry and Biogeochemistry: The atmosphere is a chemically complex system interacting both with its own various layers and with the other components of the Earth system. Our research seeks to understand the processes that affect the ozone hole, the atmosphere's ability to convert chemical species into compounds that can be readily removed from the atmosphere, and the impacts of climatically important greenhouse gases. A major challenge is to assess the importance of these global changes for the future evolution of the atmosphere, and to predict their consequences for other components of the earth system and for society. This research is conducted in the form of laboratory studies, field campaigns and other direct observations, and model development activities.
