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)

The effect of wall cooling on a compressible turbulent boundary layer [PDF]
, 1974 Experimental results are presented for two turbulent boundary-layer experiments conducted at a free-stream Mach number of 4 with wall cooling. The first experiment examines a constant-temperature cold-wall boundary layer subjected to adverse and ...

Turbulent dispersion in cloud-topped boundary layers [PDF]
, 2009 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

A two-way coupled regional urban–street network air quality model system for Beijing, China [PDF]
Geoscientific Model Development, 2023 Owing to the substantial traffic emissions in urban areas, especially near road areas, the concentrations of pollutants, such as ozone (O3) and its precursors, have a large difference compared to regional averages, and their distributions cannot be ...

Impacts of an unknown daytime HONO source on the mixing ratio and budget of HONO, and hydroxyl, hydroperoxyl, and organic peroxy radicals, in the coastal regions of China [PDF]
Atmospheric Chemistry and Physics, 2015 Many field experiments have found high nitrous acid (HONO) mixing ratios in both urban and rural areas during daytime, but these high daytime HONO mixing ratios cannot be explained well by gas-phase production, HONO emissions, and nighttime hydrolysis ...

Wet and dry deposition of atmospheric nitrogen at ten sites in Northern China [PDF]
Atmospheric Chemistry and Physics, 2012 Emissions of reactive nitrogen (N) species can affect surrounding ecosystems via atmospheric deposition. However, few long-term and multi-site measurements have focused on both the wet and the dry deposition of individual N species in large areas of ...
