This paper reviews recent progress in climate change attribution studies. The focus is on the
attribution of observed long-term changes in surface temperature, precipitation, circulation …

Fine particulate matter (PM 2.5) is a severe air pollution problem in China. Observations of
PM 2.5 have been available since 2013 from a large network operated by the China …

Surface ozone is a severe air pollution problem in the North China Plain, which is home to
300 million people. Ozone concentrations are highest in summer, driven by fast …

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 …

We applied a global 3-D chemical transport model (GEOS-Chem) to examine the variations
in the frequency and intensity in severe winter haze days (SWHDs) in Bei**g–Tian**–Hebei …

Heavy air pollution is strongly influenced by weather conditions and is thus sensitive to
climate change. Especially, for the areas with complex topography such as the Sichuan …

This study examined the spatial and temporal variations of severe particulate pollution days
(SPPDs) in China by using observed PM 2.5 concentrations during April 2013 to February …

Abstract The Bei**g–Tian**–Hebei (BTH) region has encountered increasingly severe and
frequent haze pollution during recent decades. This study reveals that El Niño–Southern …

The composition of the air we breathe is determined by emissions, weather, and
photochemical transformations induced by solar UV radiation. Photochemical reactions of …

Ozone (O 3) has become one of the most concerning air pollutants in China in recent
decades. In this study, based on surface observations, reanalysis data, global atmospheric …
