Research interests
My 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) we 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, we have developed methodologies to use LIF for detection of other radical species, such as iodine monoxide, IO, and organic peroxy radicals, RO2. We 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. Our current research focus in this area involves laboratory experiments investigating the production of radicals and other reactive gases (nitrous acid) from illuminated aerosol surfaces.
