TL;DR: The causes of haze formation in Beijing, China were analyzed based on a comprehensive measurement, including PBL (planetary boundary layer), aerosol composition and concentrations, and several important meteorological parameters such as visibility, RH (relative humidity), and wind speed/direction, finding that the formation of SPM (secondary particle matter) was accelerated in the haze events.

TL;DR: In this paper, a comprehensive measurement was carried out to analyze the heavy haze events during 2012-2013 winter in Beijing, where the measured variables include some important meteorological parameters, such as wind directions, wind speeds, relative humidity (RH), planetary boundary layer (PBL), solar radiation, and visibility.

TL;DR: A field experiment was conducted in Tianjin, China from September 9-30, 2010, focused on the evolution of Planetary Boundary Layer (PBL) and its impact on surface air pollutants.

TL;DR: In this article, the effect of heterogeneous aqueous reactions on secondary formation of inorganic aerosols during haze events was investigated by analysis of comprehensive measurements of aerosol composition and concentrations.

TL;DR: In this paper, two numerical models were applied to study the causes of haze in the Beijing region, and the results showed that the presence of high air pressure in northwest Beijing (NW-High) generally produced strong northwest winds with clean upwind air.
