Experimental and computational studies towards the identification of isoprene and α-pinene oxidation products on the surfaces of synthetic and field-collected seconary organic aerosol particles are presented. The results are discussed in the context of how they influence climate-relevant properties such as changes in supersaturation ratios required for their propensity to act as cloud condensation nuclei. The papers covered are: Climate-relevant physical properties of molecular constituents for isoprene-derived secondary organic aerosol material M. A. Upshur, B. F. Strick, V. F. McNeill, R. J. Thomson, and F. M. Geiger Atmos. Chem. Phys., 14, 10731-10740, 2014 Towards the identification of molecular constituents associated with the surfaces of isoprene-derived secondary organic aerosol (SOA) particles C. J. Ebben, B. F.
