Atmospheric Chemistry and Global Change

The changing composition in the atmosphere presents the clearest examples of global environmental change, with rising concentrations of Greenhouse gases, changing levels of aerosol particulates, global scale air pollution, and stratospheric ozone depletion. In this context, atmospheric chemistry is concerned with understanding the processes that give rise to these changing concentrations of gases and particles, and the impact that these changes have both on the climate system and air quality. All aspects of atmospheric chemistry research are conducted at the University of Toronto: laboratory studies of chemical reactions that occur in the environment, studies of cloud formation, process-oriented field measurements that diagnose chemical mechanisms in situ, pollutant monitoring, chemical transport studies, and measurements of biogeochemical emissions to the atmosphere.

Strong connections are made to others within the University of Toronto global change community, in particular to scientists involved with satellite measurements of atmospheric composition and to those interested in the biosphere and hydrological systems. In addition, atmospheric chemistry research at the University benefits from collaborations with the resources of Environment Canada and other university programs in the GTA.
