Efficiency of organic aerosols as cloud condensation nuclei


Secondary organic aerosols, aerosols produced through chemical reactions in the atmosphere from volatile compounds, affect climate directly by reflecting sunlight and by acting as cloud condensation nuclei, promoting cloud formation. The efficiency with which different types of secondary organic aerosols act as cloud condensation nuclei is important to understanding their effects on climate. Secondary organic aerosols can be composed of many different compounds, making it difficult to model their efficiency as cloud condensation nuclei. Suda et al. (2012) present a new laboratory method breaking the complex organic aerosol into subcomponents and measuring the corresponding cloud condensation nuclei efficiencies. They believe that their measured values will be useful for validating models of organic aerosols in the atmosphere.
