Atmospheric Chemistry, Aging, and Dynamics

Air quality is currently the major issue affecting both human and nature environments. The primary anthropogenic air pollutants are usually sourced from urban and industrial activities and undergo atmospheric processes to form secondary pollutants, such as ozone and fine particulate matter. As air pollutants emitting into atmosphere, photochemical reactions and oxidation occur during the transport and transformation. In addition, the formation of secondary products through atmospheric aging and the deposition process enables the cycling of elements (e.g., C, N, S, and O) in the atmosphere. This Reprint focuses on the mechanism, observation, and simulation techniques used for studying atmospheric chemistry, aging, and dynamics. To understand the fate of air pollutants, the formation, emission, transformation, chemistry, dispersion, long-range transport, deposition, and mixing of air pollutants in the atmosphere need to be investigated and studied.
