Regional severe haze represents an enormous environmental problem in China, influencing
air quality, human health, ecosystem, weather, and climate. These extremes are …

Short‑lived climate forcers (SLCFs) affect climate and are, in most cases, also air pollutants.
They include aerosols (sulphate, nitrate, ammonium, carbonaceous aerosols, mineral dust …

Abstract Fine particulate matter (PM2. 5) decreased by 30–40% across China during 2013–
2017 in response to the governmental Clean Air Action. However, surface ozone pollution …

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 …

The nationwide extent of surface ozone pollution in China and its comparison to the global
ozone distribution have not been recognized because of the scarcity of Chinese monitoring …

China's nationwide ozone monitoring network initiated in 2013 has observed severe surface
ozone pollution. This network, combined with the recent Tropospheric Ozone Assessment …

Although much attention has been paid to investigating and controlling air pollution in
China, the trends of air-pollutant concentrations on a national scale have remained unclear …

China's economic growth has significantly increased emissions of tropospheric ozone (O 3)
precursors, resulting in increased regional O 3 pollution. We analyzed data from> 1400 …

Despite the considerable reductions in primary and secondary air pollutants in China,
