中文摘要：

喷雾器的描述被要求在全球喷雾器并且为在气候上为这些喷雾器的效果建模的卫星检索减少无常。在北方中国平原(NCP ) 的喷雾器是复杂的，它提供一个好机会学习关键喷雾器为各种各样的喷雾器类型的光性质。在 2001-11 期间在北京和 Xianghe 从喷雾器机器的网络(AERONET ) 数据获得的关键光性质的簇分析被执行识别主导的喷雾器类型和他们的联系光性质。五种主导的喷雾器类型被识别。结果证明中等吸收的城市 / 工业的喷雾器在这个区域是主导的并且这种类型与季节改变了很少。弱吸收的城市 / 工业的喷雾器是下一种很普通的类型并且主要发生在夏天，由那跟随了主要在冬季发生的强壮的喷雾器。都是主要好的模式粒子。矿物质灰尘(MD ) 和弄脏的灰尘(PD ) 主要在春天发生了，到冬季列在后面，并且他们的吸收与波长减少了。另外，象折射索引和不对称现象因素那样的喷雾器动力学和光参数被检验。结果证明粗糙的模式粒子的尺寸与显示在喷雾器之间的外部混合的支配的 AOD 减少了。

英文摘要：

Characterization of aerosols is required to reduce uncertainties in satellite retrievals of global aerosols and for modeling the effects of these aerosols on climate. Aerosols in the North China Plain （NCP） are complex, which provides a good opportunity to study key aerosol optical properties for various aerosol types. A cluster analysis of key optical properties obtained from Aerosol Robotic Network （AERONET） data in Beijing and Xianghe during 2001 11 was performed to identify dominant aerosol types and their associated optical prop- erties. Five dominant aerosol types were identified. The results show that the urban/industrial aerosol of moderate absorption was dominant in the region and that this type varied little with season. Urban/industrial aerosol of weak absorption was the next most common type and mainly occurs in summer, followed by that strong aerosols occur- ring mainly in winter. All were predominantly fine mode particles. Mineral dust （MD） and polluted dust （PD） oc- curred mainly in spring, followed by winter, and their absorption decreased with wavelength. In addition, aerosol dynamics and optical parameters such as refractive index and asymmetry factor were examined. Results show that the size of coarse mode particles decreased with AOD indicating the domination of external mixing between aerosols
