Professor Martyn Chipperfield
University of Leeds
In my group we develop and use numerical models, coupled with satellite, balloon, aircraft and ground-based observations, to improve our understanding of atmospheric chemistry and its interactions. Research questions that we are currently investigating relate to the depletion and recovery of the stratospheric ozone layer, the causes of poor surface air quality and the links between climate change and atmospheric composition. A lot of this work uses a state-of-the-art 3-D atmospheric chemistry model, TOMCAT/SLIMCAT, that we have developed. We also use the much more complex global climate or 'Earth-system' models to examine feedbacks and for predictions of the future. The Wolfson Research Merit Award will allow us to study how the ozone layer is recovering in response to decreasing levels of controlled atmospheric halocarbons. We will investigate what increasing emissions of uncontrolled man-made and natural halocarbons imply for the atmosphere and for policies to protect the ozone layer.
