Abstract
The results of study of smog formation in Beijing based on the data of nephelometric measurements are presented. In smog situations, the visual range may reach the values less than 1 km. It was found that the increase of the aerosol volume concentration during smog formation is caused mainly by the growth of particles. Matched variations of the particle's effective radius, refractive index and black carbon volume fraction in a smog episode were observed.
