Iron is the most abundant redox active transition metal in mineral dust, but its role in nitrogen-containing organic carbon formation remains largely unexplored. Here, the authors show that Fe(III) catalyzes the dark oxidative oligomerization of o- a

As nitrogen-containing organic carbon of atmospheric relevance, the water uptake of two phenolic compounds, o-aminophenol and p-aminophenol, is investigated under sub- and supersaturated conditions through the lens of aerosol-cloud interactions.

Aged atmospheric volatile organic matter create secondary organic aerosols (SOA), influencing the indirect effect of aerosols. A difference in viscosity and hydrophobicity of SOA may be the primary cause of changes in hygroscopicity.

Ambient aerosol particles can undergo dynamic mixing processes as they coagulate with particles from other air masses and emission sources. Therefore, aerosols exist in a spectrum, from externally mixed to internally mixed. The mixing state of aeroso
