中文摘要	利用2008年春季中美沙尘暴联合观测试验中张掖观测站的积分浑浊度仪及同期常规气象资料,分析了有、无沙尘天气下气溶胶总散射系数(550nm)及后向散射比的日变化特征,讨论了一次典型的沙尘暴过程中气溶胶的散射特性. 结果表明,在这两种天气状况下,总散射系数日变化都呈双峰型,但峰值大小和出现的时间不同. 无沙尘日的气溶胶细粒子所占比例的变化较为明显,日较差比有沙尘日的大. 沙尘暴发生时,气溶胶总散射系数有明显的突变,积分浊度仪是对沙尘气溶胶连续监测的有效的工具
英文摘要	To monitor duststorm real-timely and continuously is helpful to understand the properties of dust aerosol. The data measured by an three-band integrating nephelometer(TSI 3563)and the routine weather observation at the meteorological observation station of CMA in Zhangye were analyzed during the Sino-US joint field experiment of dust aerosol in spring of 2008. Diurnal cycles of the atmospheric aerosol scattering coefficient(550nm)and the ratio of backscatter to total scattering in the periods with and without dust events were discussed,as well as the evolution of dust aerosol scattering properties during a typical duststorm event. The results show that, the daily variation of total scattering coefficients appears a bi-peak types during both kinds of weather conditions, but the occurred time, the peak value and magnitudes are different. The daily ranges of the proportion fine particles of for aerosol without dust days are wider than that with dust days. The total scattering coefficients are rapidly increasing when a duststorm occurred. Integrating nephelometer is a very effective instrument to monitor the dust aerosol
