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

Severe haze events with exceedingly high-levels of fine aerosols occur frequently over the
past decades in the North China Plain (NCP), exerting profound impacts on human health …

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 …

Air quality is concerned with pollutants in both the gas phase and solid or liquid phases. The
latter are referred to as aerosols, which are multifaceted agents affecting air quality, weather …

Although air quality in China has substantially improved since 2013 as a consequence of
the clean air action, severe haze events still frequently strike megacities despite strict local …

Aerosol‐planetary boundary layer (PBL) interactions have been found to enhance air
pollution in megacities in China. We show that black carbon (BC) aerosols play the key role …

Abstract The strict Clean Air Action Plan has been in place by central and local government
in China since 2013 to alleviate haze pollution. In response to implementation of the Plan …

With rapid industrialization and urbanization, China is facing a great challenge with regard
to severe fog-haze pollutions, which were characterized by high fine particulate …

The clean air actions implemented by the Chinese government in 2013 have led to
significantly improved air quality in Bei**g. In this work, we combined the in situ …

The frequent occurrence of severe air pollution episodes in China has been a great concern
and thus the focus of intensive studies. Planetary boundary layer height (PBLH) is a key …
