To obtain a thorough knowledge of PM 2. 5 chemical composition and its impact on aerosol
optical properties across China, existing field studies conducted after the year 2000 are …

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 …

The fine particulate matter (PM2. 5) problem has attracted much scientific and public
attention, due to its effects on visibility, human health, and global climate. There are three …

With rapid economic development and urbanization, China has suffered from severe and
persistent air pollution during the past years. In the work, the hourly data of PM 2.5, PM 10 …

The causes of haze formation in Bei**g, China were analyzed based on a comprehensive
measurement, including PBL (planetary boundary layer), aerosol composition and …

A comprehensive measurement was carried out to analyze the heavy haze events during
2012–2013 winter in Bei**g. The measured variables include some important …

The influence of air pollutants, especially aerosols, on regional and global climate has been
widely investigated, but only a very limited number of studies report their impacts on …

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

Black carbon (BC) has been identified to play a critical role in aerosol–planetary boundary
layer (PBL) interaction and further deterioration of near-surface air pollution in megacities …

Abstract The Comprehensive Air-quality Model with extensions (CAMx) was used to explore
the sensitivity of PM 2.5 and O 3 concentrations to four selected meteorological factors: wind …
