Professor Lisa Emberson is an environmental pollution biologist in the Department of Environment and Geography. Lisa has over 20 years’ experience in the field of air pollution and climate change focussing on impacts on agricultural yields, forest productivity and the functioning of terrestrial semi-natural ecosystems. Her research has focussed on the development of modelling methods used to tighten controls on emissions leading to air pollution, and more recently to climate change. She has developed novel ‘flux-based’ risk assessment methods based on knowledge of atmospheric exchange processes and plant eco-physiology, which can be used to assess both pollutant deposition and uptake by vegetation and related damage. This has culminated in the atmosphere-terrestrial biosphere trace gas exchange model DO3SE (Deposition of Ozone and Stomatal Exchange) now used by practitioners world-wide to estimate the exchange of water vapour and carbon as well as O3 to assess the effects of poor air quality on vegetation. This research has supported emission reduction efforts under the UNECE Convention on Long Range Transboundary Air Pollution (CLRTAP).
