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 …

High concentrations of ozone in urban and industrial regions worldwide have long been a
major air quality issue. With the rapid increase in fossil fuel consumption in China over the …

Observations of surface ozone available from∼ 1,000 sites across China for the past 5 years
(2013–2017) show severe summertime pollution and regionally variable trends. We resolve …

In recent years, ground-level ozone has become a severe ambient pollutant in major urban
areas of China, which has adverse impacts on population health. However, in-situ …

This work presents an overview of 1 yr measurements of ozone (O 3) and fine particular
matter (PM 2.5) and related trace gases at a recently developed regional background site …

Tropospheric ozone (O 3) has increased globally since the end of 20th century. Its formation
undergoes complicated photochemical reactions and processes in the lower boundary …

Volatile organic compounds (VOCs) were continuously observated in a northern suburb of
Nanjing, a typical industrial area in the Yangtze River Delta, in a summer observation period …

Ozone (O3), a main component in photochemical smog, is a secondary pollutant formed
through complex photochemical reactions involving nitrogen oxides (NOx) and volatile …

Observations of coincident high relative humidity and low surface ozone are common in air
quality data sets, but models underpredict the strength of this correlation. We perform a …

To comprehensively understand meteorological drivers for the soaring ozone pollution
across China, an advanced causality analysis model, Convergent Cross Mapping (CCM) …
