Dear Colleagues,

The Earth’s atmosphere is a complex nonlinear reaction system that involves a plethora of homogeneous (gas phase), condensed phase (solid or liquid) and interface (gas–liquid) chemical processes that drive the oxidative capacity of the atmosphere, new and secondary particle formation and cloud cover, among others. All the atmospheric reactive processes are intrinsically linked and, therefore, cannot be separated from each other. That is, to better understand many multiphase reaction processes, such as aerosol formation, one has to include homogeneous reactions. Further, pollution episodes cannot be explained using gas phase reactivity alone. Heterogeneous chemistry must be included in the models that explain different pollution episodes. As a result, a detailed chemical and physical understanding of all the atmospheric processes that include homogeneous, heterogeneous reactions, and interface reactivity has to exist to better understand different chemical and physical processes responsible for atmospheric air pollution episodes, pollution transport, and the fate of different products formed. Only then will the executive branch of the government be able to apply the appropriate mitigation strategies or pass the appropriate laws to protect the public.

Atmosphere is dedicating this Special Issue to gas phase kinetics and heterogeneous reactivity of atmospheric interest. The Special Issue in now open to both original research and review articles. Short communications are also welcome. Topics of interest include gas phase and condensed phase kinetics and dynamics, atmospheric aerosol formation, and heterogeneous reaction chemistry. Of particular interest are studies involved in the chemical processes driving the oxidative capacity of indoor and outdoor environments, atmospheric primary or secondary particle formation, cloud formation, ozone depletion/formation cycles, and nitrous acid (HONO) formation in indoor or outdoor settings. Works that look to better our living environment through industry and academia collaborations are also important.
