中文摘要: 为探讨北京地区春季气溶胶分布特征，利用机载PMS资料中的Probe PCASP 100X数据，分
析了2005年4月2日和4月17日北京地区的气溶胶垂直、水平分布的特征，并初步讨论了气象
因子和城市对气溶胶的影响。结果表明，4月2日的气溶胶平均浓度为1422.7cm-3,4月
17日的平均浓度为2142.1cm-3,平均直径分别为0.22μm和0.25μm。4月2日和4月17日
在北京沙河机场气溶胶数浓度垂直变化较大，混合层顶上下具有不同的垂直分布特征，温度
层结对气溶胶浓度的分布有重要影响，气溶胶水平分布不均匀，北京市区的气溶胶浓度较大
。
Abstract:The two flights aerosol data sampled with Passive Cavity Aerosol Spectrometer Pr
obe PCASP 100X probes of an airborne Particle Measurement System ( PMS ) in Apr
il 2 and April 17, 2005 over Beijing were analyzed. The result shows that the ma
ximum of number concentrations of aerosol in those two days were 1422.7cm-3
and 2142.1cm-3. The mean diameters were 0.22μm and 0.25μm, re
spectively. There were a strong gradient of number concentration of aerosol over
Shahe Airport. Temperature inversion and other meteorological factors, such as
the planet boundary layer, had important influence on the number concentration o
f aerosol and mean diameter. Location also has an important impact on aerosol.
