Combustion particles in the atmosphere, transformations, fate and impacts
[Principal Investigator: Professor Gordon Mcfiggans. Funder: NERC]
The objectives of this project are concerned with understanding and quantifying the contributions of combustion exhaust emissions to airborne concentrations of primary and secondary aerosol as they evolve from the urban to background regional atmosphere.
Combustion particles have major impacts on air quality and climate. As well as primary particles emitted directly, secondary particles are formed through the atmospheric oxidation of vapour phase organic compounds that are also present in the exhaust. Traditionally, primary and secondary particles have been quantified in terms of the total mass of particulate; however the human health and climate impacts are increasingly recognised to be highly dependent on the exact size and mixing state of particles.
