The Team

The GASSP team consists of scientists from the UK, the United States and Germany, and is growing all the time. The project is a collaboration of the Universities of Leeds, Oxford and Manchester, with international data partners. The team consists of expertise in global aerosol modelling combined with aerosol observations from ship, aircraft and land-based sites, as well as statistical modelling.

Principal Investigators

Ken Carslaw. University of Leeds
Ken Carslaw is the Leeds principal investigator of the GASSP project. The Global Model of Aerosol Processes (GLOMAP) developed by Ken’s research group has been used to study a wide range of aerosol processes in the atmosphere, including new particle formation, marine aerosol, dust emission and transport, and cloud condensation nuclei. GLOMAP is also being used in an Earth System model to study the interactions between aerosol, the oceans and the biosphere from seasonal to palaeo timescales.

Philip Stier. University of Oxford
Philip Stier is the Oxford PI on GASSP. Philip is a University Lecturer in Atmospheric Physics at the Department of Physics and a Fellow in Physics at Oriel College, University of Oxford. Global aerosol and cloud microphysics are a key focus of Philip’s research, combining global aerosol-climate models (HadGEM-UKCA, ECHAM-HAM) with in-situ and remote sensing observations. Philip is co-chair of the AeroCom intercomparison project working group on aerosol radiative forcing.

Hugh Coe. University of Manchester
Hugh Coe is a co-investigator on GASSP, responsible for collection and harmonisation of aerosol measurements. Hugh’s current research interests include: biomass burning and dust aerosols; the long range transport of pollution aerosol; aerosol-cloud interactions; organic aerosol; transformation and transport of aerosols on urban to regional scales.
