The atmosphere is central to many of the environmental problems faced by society. Climate change, air quality degradation and ecosystem issues are all significantly impacted by atmospheric chemistry.

Our understanding of atmospheric chemistry is driven by a variety of experimental types. Laboratory studies, studies in atmospheric chambers, short term field experiments and long term monitoring all provide insight into the processes controlling the composition of the atmosphere.

We integrate our understanding of these processes through the use of atmospheric models. These are sophisticated computer programs which quantify the processes going on in the atmosphere which allow prediction of the past, present and future state of the atmosphere.

Professor Evans’ interests lie in the use of these models to better understand the atmosphere and thus improve our predictive capability of the composition of the atmosphere. Improved predictive capability will allow better policy options to be evaluated and devised.
