      This paper shows how the advanced chemical transport model CMAQ can be used to estimate future levels of PM2.5 in the UK, the key air pollutant in terms of human health effects, but one which is largely made up from the ...

    • Cloud forming potential of secondary organic aerosol under near atmospheric conditions 

      Duplissy, J.; Gysel, M.; Alfarra, M. R.; Dommen, J.; Metzger, A.; Prevot, A. S. H.; Weingartner, E.; Laaksonen, A.; Raatikainen, T.; Good, N.; Turner, S. F.; McFiggans, G.; Baltensperger, U. (2008-02-15)
      Cloud droplets form by nucleation on atmospheric aerosol particles. Populations of such particles invariably contain organic material, a major source of which is thought to be condensation of photo-oxidation products of ...

    • Composition and properties of atmospheric particles in the eastern Atlantic and impacts on gas phase uptake rates 

      Allan, J. D.; Topping, D. O.; Good, N.; Irwin, M.; Flynn, M.; Williams, P. I.; Coe, H.; Baker, A. R.; Martino, M.; Niedermeier, N.; Wiedensohler, A.; Lehmann, S.; Mueller, K.; Herrmann, H.; McFiggans, G. (2009)
      Marine aerosol composition continues to represent a large source of uncertainty in the study of climate and atmospheric chemistry. In addition to their physical size and chemical composition, hygroscopicity plays a significant ...

      Results from a measurement study performed in the Tropical Atlantic on board the RHaMBLe Discovery Cruise D319 are presented. Measurements of aerosol composition, hygroscopicity and CCN activity were used to test the ability ...

    • Influences on the fraction of hydrophobic and hydrophilic black carbon in the atmosphere 

      McMeeking, G. R.; Good, N.; Petters, M. D.; McFiggans, G.; Coe, H. (2011)
      Black carbon (BC) is a short term climate forcer that directly warms the atmosphere, slows convection, and hinders quantification of the effect of greenhouse gases on climate change. The atmospheric lifetime of BC particles ...

    • Instrumentational operation and analytical methodology for the reconciliation of aerosol water uptake under sub- and supersaturated conditions 

      Good, N.; Coe, H.; McFiggans, G. (2010)
      The methodology for the operation and calibration of a hygroscopicity tandem differential mobility analyser (HTDMA) and cloud condensation nuclei counter (CCNc) for size-resolved measurements of aerosol water uptake are ...
