Abstract The climate effects of atmospheric aerosol particles serving as cloud condensation nuclei (CCN) depend on chemical composition and hygroscopicity, which are highly variable on spatial and temporal scales. Here we present global CCN measureme

Chemical models that describe the atmospheric multiphase (gas/aqueous) system often include detailed kinetic and mechanistic schemes describing chemical reactions in both phases. The present study explores the importance of properties including the c

Bioaerosols include bacteria that comprise about 5. Generally, the highest importance of biodegradation is identified for large droplets and at pH ~5, which may be considered representative for remote locations. The results are highly sensitive to th

Redox reactions transition metal ions (TMI), such as iron and copper, affect the concentrations of reactive oxygen species (ROS) in atmospheric cloud droplets and aqueous aerosol particles. Copper and iron have distinct emission sources resulting in

Primary biological aerosol particles (PBAPs), such as bacteria, viruses, fungi, and pollen, represent a small fraction of the total aerosol burden. Based on process model studies, we identify trends in the relative importance of PBAP properties, e.g.

Formic and acetic acids are ubiquitous components in the atmospheric gas and condensed (clouds, particles, fogs) phases. They originate from various anthropogenic or biogenic sources.Their production and loss processes in the atmosphere are usually a
