Measurements of cloud condensation nuclei (CCN) concentrations (cm−3)between 0.2 and 1.0% supersaturation, aerosol size distribution andchemical composition were performed at a remote marine site in the easternMediterranean, from September to October 2007 during the FAME07 campaign.Most of the particles activate at ~0.6% supersaturation,characteristic of the aged nature of the aerosol sampled. Application ofKöhler theory, using measurements of bulk composition, sizedistribution, and assuming that organics are insoluble resulted in agreementbetween predicted and measured CCN concentrations within 7±11% forall supersaturations, with a tendency for CCN underprediction(16±6%; r2=0.88) at the lowest supersaturations (0.21%). Includingthe effects of the water-soluble organic fraction (which represent around70% of the total organic content) reduces the average underprediction bias at thelow supersaturations, resulting in a total closure error of 0.6±6%.Using threshold droplet growth analysis, the growth kinetics of ambient CCNis consistent with NaCl calibration experiments; hence the presence of agedorganics does not suppress the rate of water uptake in this environment. Theknowledge of the soluble salt fraction is sufficient for the description ofthe CCN activity in this area
