Aerosol composition, oxidation properties, and sources in Beijing: results from the 2014 Asia-Pacific Economic Cooperation summit study [PDF]
Atmospheric Chemistry and Physics, 2015 The mitigation of air pollution in megacities remains a great challenge because of the complex sources and formation mechanisms of aerosol particles. The 2014 Asia-Pacific Economic Cooperation (APEC) summit in Beijing serves as a unique experiment to ...

Evaluation of Ozone Formation Potential of Formaldehyde Using Smog Chamber Data
Aerosol and Air Quality Research, 2023 Formaldehyde (HCHO) is one of the important O3 precursors in the atmospheric environment, but the mechanism for HCHO photochemical reactions is not very clear now. In the present study, the effects of relative humidity (RH) and initial VOC/NOx ratio (RCN)

Turbulent dispersion in cloud-topped boundary layers [PDF]
, 2008 Compared to dry boundary layers, dispersion in cloud-topped boundary layers has received less attention. In this LES based numerical study we investigate the dispersion of a passive tracer in the form of Lagrangian particles for four kinds of atmospheric

Measurements of aircraft wake vortices in ground proximity within an atmospheric boundary layer wind tunnel [PDF]
, 2010 The vortex wake characteristics of aircraft during landing and take-off are of interest in connection with both the safety of following aircraft penetrating the vortex and the dispersion of engine exhaust plumes. A series of measurements were carried out
