Description:

A large fraction of atmospheric aerosols acts as cloud condensation nuclei, but the atmospheric chemical and physical processes to form cloud condensation nuclei (CCN) remain uncertain. We welcome all studies that present new knowledge of atmospheric chemistry and physics in CCN formation and transformation using measurements and/or modeling tools. Relevant topics include aerosol chemical and physical processes that affect new particle formation and growth, heterogeneous/multiphase chemistry, chemical aging, mixing state/phase state variations, cloud condensation activities, as well as cloud processing of aerosols, such as cloud chemistry, wet scavenging, and resuspension.
