中文摘要	兰州大学与中国科学院,中国气象局,美国马里兰大学,美国能源部等研究机构于2008年46月进行了中美沙尘暴联合观测试验,观测点设在张掖国家气候观象台,兰州大学半干旱气候与环境观测站(SACOL)和SACOL景泰移动观测点.利用颗粒物烟尘吸收光度计和TSI积分浑浊度仪资料分析了张掖地区气溶胶吸收和散射特性.结果表明:气溶胶吸收系数,总散射和后向散射系数日变化趋势一致,基本呈双峰型,峰值分别出现在08:00和22:00,夜间的值较白天偏大;气溶胶吸收系数,总散射和后向散射系数的月平均值在4月最大,5月次之,6月最小;450,550和700 nm波段的气溶胶单次散射反照率主要集中在0.70.9
英文摘要	The first China-US joint dust field observation was carried out by Lanzhou University, Chinese Academy of Sciences, China Meteorological Administration, University of Maryland and the Department of Energy,USA during the period of April and June 2008.The observation sites are located respectively at Zhangye National Climatological Observatory, Semi-Arid Climate and Environment Observatory of Lanzhou University(SACOL), and Jingtai with the Mobile Facilities of SACOL.The measurements of Particle/Soot Absorption Photometer and TSI Integrating Nephelometer are used to analyze the aerosol absorption and scattering properties in Zhangye. The analysis shows that the diurnal coefficient {evolutions} in aerosol absorption, total scattering and backscattering present the same trends with their bi-peaks, respectively at 08:00 and 22:00, which are generally higher at nighttime than in daytime. The monthly average coefficient is the highest in April and low in succession in May and June. The frequency {analysis} of the aerosol single scattering albedo(SSA) shows that the magnitudes of SSA at 450,550 and 700 nm {wavelengthes} are mainly within 0.70.9
