Background
Neil is experienced in the international coordination of atmospheric research and in ensuring that the understanding gained is transferred to the policy and public fields. He was co-chair of the Stratosphere-troposphere Processes and their Role in Climate of the World Climate Research Programme (2014-2022) and is now a member of the WCRP Safe Landing Lighthouse promoting understanding of what a safe climate is and how we avoid the many pitfalls in maintaining it. He has been involved in many international assessments of ozone depletion and climate change. He was awarded the NERC 50th anniversary International and the Overall Impact Awards for our role in successful development of the Montreal Protocol on Substances that Deplete the Ozone Layer. Neil has a BA in Chemistry from Oxford University and a PhD from the University of California at Irvine. He was appointed Chair in Atmospheric Informatics in April 2016.
I have started a blog on climate and science issues which reflects my personal views: https://climatethoughts320711548.wordpress.com/blog/.
Research opportunities
A wealth of measurements exists that has been collected in monitoring networks, during focussed field campaigns and by satellite instruments. Great opportunities exist to exploit these data to understand a range of atmospheric problems. In addition to using commercial instruments, Neil's group have developed and constructed instruments capable of running autonomously to make observations for months and years at a time. The current generation of custom-built instruments are used to make measurements of short-lived, reactive compounds which are important for climate change and air pollution. Dimethyl sulphide has been measured in the Arctic and Antarctic to shed light on low level cloud formation.
Neil is playing a leading role on the environmental side of Cranfield's work on Sustainable Aviation and is particularly interested in the non-CO2 impacts of aviation which are principally related to contrail and cirrus formation and to NOx and particulate emissions. He was part of a team who prepared a report on non-CO2 impacts for the SWAG合集 Department for Transport.
Current activities
Emissions of greenhouse gases in the United Kingdom. We develop and use analytical techniques using our own measurements to quantify emissions at local scales to pinpoint where emissions are occurring (landfills, towns and cities, agriculture). We are currently collaborating in projects estimating London's emissions at borough level and in combining information on SWAG合集 emissions from a number of sources to provide a one-stop shop.
Terrestrial measurements of isoprene. Gases emitted from temperate and tropical forests (isoprene and terpenes) and palm oil plantations have important impacts on the global atmosphere. For the last 4 summers, isoprene was measured at Wytham Woods, Oxford and used to study the effects of heat, drought, etc.
Oceanic emissions of dimethylsufhide. Dimethylsulfide is an important natural precursor for particle formation over the oceans and plays an especially important role in the Arctic and Antarctic where we measure its concentrations from ships and coastal sites to assess its role in cloud formation and climate. We are currently making measurements at the BAS Rothera station and on the RRS Sir David Attenborough in the South Atlantic.
Air quality: additional measurements of pollutants were made across the Oxford - Milton Keynes - Cambridge Arc to assess the impact of the COVID-19 restrictions and changes in habits (e.g. traffic). A special focus is on atmospheric particles (PM2.5) in selected cities. This work builds around the facilities in the Cranfield Urban Observatory. We collaborate with colleagues making similar measurements in South East Asia, particularly in Malaysia and Vietnam where
