Biogenic cloud nuclei in the central Amazon during the transition from wet to dry season
Whitehead, James D.; Darbyshire, Eoghan; Brito, Joel; Barbosa, Henrique M.J.; Crawford, I.A.; Stern, Rafael; Gallagher, Martin W.; Kaye, Paul; Allan, James D.; Coe, H.; Artaxo, Paulo; McFiggans, G. B. (2016-08-03)The Amazon basin is a vast continental area in which atmospheric composition is relatively unaffected by anthropogenic aerosol particles. Understanding the proper- ties of the natural biogenic aerosol particles over the ... -
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 ... -
Consistency between parameterisations of aerosol hygroscopicity and CCN activity during the RHaMBLe discovery cruise
Good, N.; Topping, D. O.; Allan, J. D.; Flynn, M.; Fuentes, E.; Irwin, M.; Williams, P. I.; Coe, H.; McFiggans, G. (2010)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 ... -
Widening the gap between measurement and modelling of secondary organic aerosol properties?
Good, N.; Topping, D. O.; Duplissy, J.; Gysel, M.; Meyer, N. K.; Metzger, A.; Turner, S. F.; Baltensperger, U.; Ristovski, Z.; Weingartner, E.; Coe, H.; McFiggans, G. (2010)The link between measured sub-saturated hygroscopicity and cloud activation potential of secondary organic aerosol particles produced by the chamber photo-oxidation of alpha-pinene in the presence or absence of ammonium ...
