This research project focuses on modeling atmospheric chemistry and climate from the surface to the top of the stratosphere, using sophisticated chemistry-climate models. The research areas include: Anthropogenic ozone depletion, the ozone hole, and associated questions, such as the return date of stratospheric ozone to historical levels. Global tropospheric air pollution, the oxidizing capacity of the troposphere, and tropospheric ozone chemistry. Global and regional climate change and its links with atmospheric chemistry. The research started in 2002 and has revealed a number of key findings to date. We have contributed to international modeling efforts that have informed the 2010 World Meteorological Scientific Assessment of Ozone Depletion and the 2007 IPCC 4th Assessment Report of Climate Change. |
