Short summary
We studied how sunlight changes natural organic matter in fog droplets and the tiny airborne particles formed after the water evaporation. Advanced analyses showed that sunlight makes this material more oxidized, nitrogen-enriched, chemically transformed, and different in light absorption and volatility. These sunlight-driven changes influence the particles’ behavior in the air, affecting air quality, climate, and how long they remain suspended in the atmosphere.

Soot particles, also known as black carbon (BC), have important implications for global climate and regional air quality. After the particles are emitted, BC can be coated with other material, impacting the aerosol properties. We selectively measured the composition of particles containing BC to explore their sources and chemical transformations in the atmosphere. We focus on a persistent, multiday fog event in order to study the effects of chemical reactions occurring within liquid droplets.

Short summary
D5 is an emerging anthropogenic pollutant that is ubiquitous in indoor and urban environments, and the OH oxidation of D5 forms secondary organosiloxane aerosol (SOSiA). Application of a kinetic box model that uses a volatility basis set (VBS) showed that consideration of oxidative aging (aging-VBS) predicts SOSiA formation much better than using a standard-VBS model. Ageing-dependent parameterization is needed to accurately model SOSiA to assess the implications of siloxanes for air quality.

Anthropogenic fugitive dust in East Asia not only causes severe coarse particulate matter air pollution problems, but also affects fine particulate nitrate. Due to emission control efforts, coarse PM decreased steadily. We find that the decrease of coarse PM is a major driver for a lack of decrease of fine particulate nitrate, as it allows more nitric acid to form fine particulate nitrate. The continuing decrease of coarse PM requires more stringent ammonia and nitrogen oxides emission controls.

The 2016 Korea–United States Air Quality (KORUS-AQ) field campaign provided a unique set of observations to improve our understanding of PM2.5 pollution in South Korea. Models typically have errors in simulating PM2.5 in this region, which is of concern for the development of control measures. We use KORUS-AQ observations to improve our understanding of the mechanisms driving PM2.5 and the implications of model errors for determining PM2.5 that is attributable to local or foreign sources.

Short summary
We investigated how organic particles behave during severe winter haze in Seoul using advanced real-time measurements. We found that even highly oxidized particles can remain volatile, and a rare nitrogen-containing type emerges under cold, stagnant conditions. We interpret both as products of limited atmospheric processing and combustion-related sources. These findings help improve understanding of pollution formation and evolution.
