UK Principal Investigating Partners


  • Dr. Eiko Nemitz (UK (PI) - is an environmental physicist with >20 years of experience in micrometeorological flux measurements of gases and aerosol, and he led the extension of this work to provide top-down emission estimates in cities in NERC and EU projects (e.g. CityFlux, ClearfLo, AIRPOLL-Beijing). He has pioneered the use of new flux instrumentation, incl. aerosol mass spectrometry. Dr Nemitz has led several NERC grants and major components of EU projects, co-ordinating budgets of up to €3.5M.
  • Dr. Ben Langord - specialises in the measurement of surface/atmosphere exchange fluxes of VOC by PTR-MS and aerosol chemical compounds by AMS.
  • Dr Ulrike Dragosits - contributes to the official UK emissions inventory of NH3, CH4 and N2O, and leads on the spatial distribution of agricultural emissions and a range of non-agricultural sources.
  • Dr Mhairi Coyle - has >20 years of experience in the flux measurement of reactive gases.

  • Dr James Lee - is Senior NCAS Research Fellow, with responsibility for coordinating observations in the field of tropospheric oxidant chemistry and emissions of gas phase air pollutants. Dr. Lee has >15 years of experience in coordinating large measurement intensive field campaigns.
  • Dr Jaqueline Hamilton - has spent 15 years studying secondary organic aerosols (SOA), developing novel high-resolution methods to identify their gas phase sources and quantifying the composition of SOA, identifying new pathways for their formation and insights into their impact on human health and climate. She was awarded the 2009 Desty Memorial Award for this work.
  • Dr David Carslaw - has expertise in the quantification of vehicle emissions and the development of novel receptor modelling techniques. Recent work based on vehicle emission remote sensing quantified, for the first time, NOx and NO2 emissions for the European vehicle fleet. He joined the UK Air Quality Expert Group (AQEG) in 2002.

  • Prof Nick Hewitt - has worked on volatile organic compounds since 1990. His work has included laboratory studies, field measurements and modelling, including the measurement of VOC fluxes from the surface to the atmosphere by micro-meteorological methods.
  • Dr Oliver Wild - is a Reader with >20 years of experience in developing and applying models of atmospheric chemistry and transport. He is a member of the UNECE LRTAP task force on Hemispheric Transport of Air Pollutants (HTAP) and a lead author on the HTAP Assessment Report on intercontinental transport of pollutants and their impacts on agriculture, human health, and climate.

  • Dr James Allan - is a Senior Research Fellow and NCAS scientist who specialises in atmospheric aerosol measurements, particularly with Aerosol Mass Spectrometry (AMS), and multivariate analyses and modelling of optical properties. He has published 123 peer-reviewed publications (h-index 41). In 2013 he was awarded the prestigious EAC Smoluchowski Award for his contributions to AMS.
  • Ernesto Reyes Villegas - is a student completing his PhD in the analysis of complex aerosol data in polluted environments, using instruments such as the AMS, ACSM and chemical ionisation mass spectrometer.
