Atmospheric Chemistry, Aging, and Dynamics

Dear Colleagues,

Air quality is currently the major issue that affects 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 oxidations occur during the transport and transformation. In addition, the formation of secondary products through atmospheric aging and deposition process enables the cycling of elements (e.g., C, N, S, and O) in the atmosphere. This Topic will focus on the mechanism, observation, and simulation techniques used for studying atmospheric chemistry, aging, and dynamics. To understand the fate of air pollutants, formation, emission, transformation, chemistry, dispersion, long-range transport, deposition, and mixing of air pollutants in the atmosphere need to be investigated and studied.

In this Topic, original research articles and reviews are welcome. The main topics include (but are not limited to):

• Aerosol and gas mixing;
• Air pollutants in the urban environment;
• Atmospheric chemistry in gas and aerosol formation;
• Atmospheric chemistry in emission process;
• Atmospheric oxidation and aging of air pollutants;
• Atmospheric photochemical phenomenon;
• Fate of air pollutants;
• Long-range transport of air pollutants;
• Tropospheric and stratospheric chemistry;
• Secondary air pollutants (gas and aerosol).

We look forward to receiving your contributions.
