Prediction of cloud condensation nuclei activity for organic compounds using functional group contribution methods
A wealth of recent laboratory and field experiments demonstrate that organic aerosol composition evolves with time in the atmosphere, leading to changes in the influence of the organic fraction to cloud condensation nuclei (CCN) spectra. There is a need for tools that can realistically represent the evolution of CCN activity to better predict indirect effects of organic aerosol on clouds and cl...
متن کاملOrganic Functional Group Contributions to Cloud Condensation Nuclei in the Arctic During ICEALOT 2008
Cloud condensation nuclei (CCN) affect cloud droplet formation processes as well as number concentration. An increase in cloud droplet number concentration influences the Earth’s radiative balance by increasing the reflected incoming solar radiation. Chemical composition influences the properties of the aerosol particles, which impact their ability to act as CCN. Organic functional groups in pa...

متن کاملAerosol hygroscopicity and cloud condensation nuclei activity during the ACExp campaign: implications for cloud condensation nuclei parameterization
Aerosol hygroscopicity and cloud condensation nuclei (CCN) activity under background conditions and during pollution events are investigated during the AerosolCCN-Cloud Closure Experiment (ACExp) campaign conducted at Xianghe, China in summer 2013. A gradual increase in size-resolved activation ratio (AR) with particle diameter (Dp) suggests that aerosol particles have different hygroscopicitie...
