Ozone (O3) in the troposphere is an air pollutant and a greenhouse gas. In mainland China,
after the Air Pollution Prevention and Action Plan was implemented in 2013—and despite …

In the past decade, ozone (O 3) pollution has become a severe environmental problem in
China's major cities. Here, based on available observational records, we investigated the …

Ozone pollution in China is influenced by meteorological processes on multiple scales.
Using regression analysis and weather classification, we statistically assess the impacts of …

Rapid population growth and industrialization have driven substantial increases in Asian
ozone precursor emissions over the past decade, with highly uncertain impacts on regional …

This study investigated the air pollution characteristics of synoptic-scale circulation in the
Beijing megacity, and provided quantitative evaluation of the impacts of circulation patterns …

Elevated ground-level ozone (O 3), reflecting atmospheric oxidative capacity, are of
increasing concern. High levels of total oxidants (O x= O 3+ NO 2) have been persistently …

ABSTRACTPM2. 5 is the major pollutant in most cities of China, especially contributed
significantly to the poor air quality in Beijing. This study aimed to investigate the long-term …

China is currently one of the countries impacted by severe atmospheric ozone (O 3) and
particulate matter (PM) pollution. Due to their moderately long lifetimes, O 3 and PM can be …

Trends in air quality across the Northern Hemisphere over a 21-year period (1990–2010)
were simulated using the Community Multiscale Air Quality (CMAQ) multiscale chemical …

To better understand the chemical speciation of volatile organic compounds (VOCs) and
their role in ground-level ozone formation in the Beijing-Tianjin-Hebei region, China …
