Dr. Percival’s research studies the sources and fate of pollution in the atmosphere. In particular, on the photochemical oxidation of atmospheric volatile organic compounds (VOCs) which has major implications for urban and regional air quality, acid deposition, and global climate.
His research is in three main areas: the first is the development of methods to directly observe fundamental gas phase kinetics of key reactions of atmospheric importance in the laboratory. The second area of work focuses on the development of novel analytical techniques to quantify trace species in the atmosphere and the third area is on the study of the interaction of gases with aerosols. The data coming from his laboratory are providing an essential basis for the interpretation of atmospheric behavior and helping us to construct diagnostic and forecasting models of the atmosphere.

Prof. Nozière’s research interests are the reactivity and properties of organic compounds in the Earth atmosphere that affect the composition or oxidative capacity of Earth's atmosphere, air quality, or climate. My activities include laboratory studies and atmospheric analyses, and often involve the development of new methods or techniques.

Lisa Whalley英国 · 利兹大学Dr. Lisa Whalley’s research is supported by the National Centre for Atmospheric Science (NCAS) which is based in Leeds and funded by NERC. Her research interests involve atmospheric measurements, modelling studies and laboratory experiments. She is a member of the Atmospheric and Planetary Chemistry group (http://www.chem.leeds.ac.uk/research/groups/atmospheric-and-planetary-chemistry.html) in the School of Chemistry. Her research interest lies in understanding the chemistry responsible for the processing of trace gases in the atmosphere through field observation and comparison of these observations with detailed chemistry models based on the Master Chemical Mechanism (MCM). The hydroxyl radical (OH) is the main daytime oxidant in the atmosphere, responsible for the removal of many man-made and natural emissions. Using laser induced fluorescence (LIF) they have made measurements of OH on over 20 field projects in a variety of environments including Polar, Urban, Rural and Tropical regions with the aim of identifying the important chemical processing occurring in these key global areas. Alongside OH measurements, they have developed methodologies to use LIF for detection of other radical species, such as iodine monoxide, IO, and organic peroxy radicals, RO2. They are also involved in the development of new instrumentation and algorithms for determining photolysis rates from the ground and also on board the UK research aircraft. Heterogeneous aerosol chemistry is an important process that is able to modify the concentration of trace gases and radicals. Their current research focus in this area involves laboratory experiments investigating the production of radicals and other reactive gases (nitrous acid) from illuminated aerosol surfaces.
