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)

Similarity theory and calculation of turbulent fluxes at the surface for the stably stratified atmospheric boundary layers [PDF]
, 2006 In this paper we revise the similarity theory for the stably stratified atmospheric boundary layer (ABL), formulate analytical approximations for the wind velocity and potential temperature profiles over the entire ABL, validate them against large-eddy ...

Understanding the daily cycle of evapotranspiration: a method to quantify the influence of forcings and feedbacks [PDF]
, 2010 A method to analyze the daily cycle of evapotranspiration over land is presented. It quantifies the influence of external forcings, such as radiation and advection, and of internal feedbacks induced by boundary layer, surface layer, and land surface ...

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 ...

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 ...
