Abstract: Aerosol data sampled with the passive cavity aerosol spectrometer probe (PCASP) of airborne Particle Measurement System (PMS) in different atmospheric conditions during September in 2004 over Beijing are analyzed. The results show that the number concentration of aerosol in the south of Beijing is higher than that in the north, and different atmospheric conditions, such as temperature inversion, wind speed have important effects on the distribution of aerosol at different altitudes.

Key words: aerosol, boundary layer, air pollution

摘要: 利用2004年9月机载PMS系统在北京地区不同天气条件下的气溶胶观测资料,分析了北京市区上空不同高度气溶胶浓度的水平分布特征,并讨论其与天气条件的关系。结果表明,在北京市区南部气溶胶浓度大于北部。逆温层、风速等天气条件对气溶胶在不同高度的分布有重要影响。
