Short summary
Urban air pollution is one of the greatest environmental concern in 21st century. In this paper, we trace temporal evolutions of aerosol hygroscopicity and effective density during a representative particulate matter episode, which provide a strong support on that severe haze pollution can be formed in highly polluted areas by the initial accumulation of gas-phase and particulate pollutants under stagnant meteorological conditions and subsequent rapid particle growth by secondary processes.
