Air quality issues plague public health in many areas around the world. Once emitted, the concentrations of ambient air pollutants are determined by a combination of chemical and dispersion processes in the atmospheric boundary layer. Boundary-layer meteorology influences these processes in different ways, thereby playing an important role in modulating the ambient air quality.

Although some progress has been made in understanding the atmospheric boundary layer in the past few decades, our knowledge is still limited. Thus, further efforts in investigating boundary-layer/air pollution meteorology through observational, experimental, and numerical methods are warranted for us to reduce air pollution around the world.

We solicit high quality, original research as well as review articles on the advances in boundary-layer/air pollution meteorology.

Potential topics include, but are not limited to:

• Observational/experimental/numerical studies of the physics and chemistry of the atmospheric boundary layer
• Trends in ambient pollutant concentrations in the boundary layer
• New methods for measuring ambient pollutants
• Improving parameterization schemes of the atmospheric boundary layer
• Land-surface processes/surface fluxes
• Mesoscale circulations/effects
• Vegetation-atmosphere interactions
