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 between 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.




The GASSP data team

Kirsty Pringle. University of Leeds

Kirsty Pringle is an Aerosol Support Scientist and member of the Center for Environmental Modelling and Computation at the University of Leeds.

Kirsty is responsible for pre-processing GASSP data, and incorporating new observational data into the GASSP database.  If you would like to add your data to the GASSP database please email:

The founding GASSP data scientist was Carly Reddington, now a PDRA at the University of Leeds working on wildfire aerosol.


Duncan Watson-Parris. University of Oxford

Duncan Watson-Parris is research fellow at the University of Oxford and author of the Community Intercomparison Suite a python software package designed to facilitate model observation comparison. CIS has been designed for use with the GASSP database (and other common environmental data).

Duncan is an expert user of the GASSP database, and a GASSP data scientist.
