Shona is a Research Associate at the Wolfson Atmospheric Chemistry Laboratories at the University of York. Much of her previous work has been centred around measuring and understanding gas-phase emissions from the UK oil and gas industry both on and offshore. This has included making long-term, ground-based measurements at UK hydraulic fracturing sites, as well as extensive airborne campaigns on-board the FAAM research aircraft studying offshore emissions from oil and gas platforms in the North Sea. More recently Shona has been working on understanding the contribution made by vehicle emissions to impacts on urban air quality. Specifically, she hopes to develop new analysis approaches to better utilise mobile measurement data to understand the effects of congestion on air quality.
This talk considers how fast response mobile measurements of air pollutants and carbon dioxide can be used to develop an improved spatial understanding of vehicle emissions. The spatial variation of vehicle emissions is complex and is affected by both the vehicle fleet and driving conditions. A particular goal is developing an improved understanding of congestion and its effect on emissions and near-road air quality, as well as studying the influence of different vehicle emissions after-treatment technologies. This project aims to bring together large mobile measurement data sets of vehicle activity and concentration measurements with detailed vehicle emission remote sensing data to develop an improved understanding of the spatial variation in emissions.
