Abstract

The data of consecutive observations of Micro Pulse Lidar (MPL), achieved at in the northern suburb of Nanjing, was analysed and variations of the aerosol with temperature, humidity and SO₂ concentration data were preliminary discussed. It was showed that at the near surface (300m) depolarization ratio of aerosol was larger at 0~10 o'clock with the peak value up to 0.163 at 05:00AM; the depolarization ratio had a negative correlation with temperature, strong positive correlation with humidity and SO₂ concentration; under the conditions of low temperature, high relative humidity and high SO₂ level, SO₂ was more likely to be oxidized to produce non spherical, sulfate aerosol particles.

Key words： lidar sulfate aerosol depolarization ratio temperature humidity SO₂ concentration
