Ozone weekend effects in the Beijing–Tianjin–Hebei metropolitan area, China [PDF]
The ozone weekend effect (OWE) was first investigated in the metropolitan area of Beijing–Tianjin–Hebei (BTH), China, using in situ measurements from the Atmospheric Environment Monitoring Network from July 2009 to August 2011.

A two-way coupled regional urban–street network air quality model system for Beijing, China [PDF]
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]
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 ...

An improved process-oriented hydro-biogeochemical model for simulating dynamic fluxes of methane and nitrous oxide in alpine ecosystems with seasonally frozen soils [PDF]
The hydro-biogeochemical model Catchment Nutrient Management Model – DeNitrification-DeComposition (CNMM-DNDC) was established to simultaneously quantify ecosystem productivity and losses of nitrogen and carbon at the site or catchment scale.

Modeling the Impact of Atmospheric Warming on Staple Crop Growth in China in the 1960s and 2000s
Responses of crop growth to climate warming are fundamental to future food security. The response of crops to climate change may be subtly different at their growing stages.

Wet and dry deposition of atmospheric nitrogen at ten sites in Northern China [PDF]
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 ...

Chemical characterization and source identification of PM2.5 at multiple sites in the Beijing–Tianjin–Hebei region, China [PDF]
The simultaneous observation and analysis of atmospheric fine particles (PM2.5) on a regional scale is an important approach to develop control strategies for haze pollution.

Extreme fluctuations of vertical velocity in the unstable atmospheric surface layer [PDF]
In this paper, we propose a new method to extract the extreme fluctuations of vertical velocity in the unstable atmospheric surface layer. Unlike the commonly used conditional sampling analysis, this method defines a threshold by using a systematical ...
