| 摘 要： | 中国气象局在沙尘暴监测网各站点安装了积分浊度计，这是国内首次利用积分浊度计进行大面积气溶胶光学性质的监测。文章选取北京观象台2003年9月2日至11月18日散射系数数据以及部分PMIO质量浓度数据，结合气象资料分析了观测期间散射系数的变化特征，散射系数与PMIO质量浓度以及能见度的关系，得出观测期间散射系数的平均值(标准偏差)为306．2Mm^-1(292．78Mm^-1)；风速对散射系数有重要影响；散射系数与PMIO质量浓度有较好的相关性(r=0．761)，与能见度存在负相关关系(r=-0．716)。

| Abstract: | Integrating nephelometers were installed at each station of the dust storm monitoring net by the China Meteorological Administration. This is the first time that the optical porperties of aerosol were monitored using integrating nephelometers on a large scale in China. The variation feature of scattering coefficient and the relation between scattering coefficient and PM10 mass concentration and visibility were analyzed based on the primary principles of integrating nephelometers,using the scattering coefficient data and PM10 mass concentration from Beijing Observatory and meteorological data from September to November 2003.The results indicate that the mean value (standard deviation) is 306 2 Mm -1(292 78 Mm -1).Wind speed has an important effect on scattering coefficient,while scattering coefficient has good correlation with PM10 mass concentration ( r = -0 761),and there exists a negative correlation between scattering and visibility ( r = -0 716). |
