The role of new particle formation (NPF) events and their contribution to haze formation
through subsequent growth in polluted megacities is still controversial. To improve the …

The simultaneous observation and analysis of atmospheric fine particles (PM 2.5) on a
regional scale is an important approach to develop control strategies for haze pollution. In …

Extreme haze episodes repeatedly shrouded Beijing during the winter of 2012–2013,
causing major environmental and health problems. To better understand these extreme …

To evaluate the wintertime regional brown haze in northern China, trace gases and aerosols
were measured at an urban site between 9 and 20 November 2009. Ion chromatography …

Despite frequent haze pollution in China in recent years, our knowledge of regional pollution
episodes associated with air transport and synoptic weather systems is limited. In this study …

Airborne particulate matter (PM) was collected in Beijing between 24 February and 12
