Short summary
Cloud condensation nuclei (CCN) play a critical role in cloud formation which affects solar radiation and climate. We employed advanced instruments to measure aerosol hygroscopicity and chemical composition and used them to predict CCN activity. Our results found that the CCN activity was largely dependent on the hygroscopicity parameter and the surface tension of the particles. Our study highlights the need for evaluating the effects of organics in order to accurately predict CCN activity.
