分析了北京地区沙尘天气地面颗粒化学成分与柱状气溶胶光学性质的关系。颗粒中典型元素Si、Fe、Ti、K等均与部分柱气溶胶光学性质（如气溶胶光学厚度、辐射强迫等）有很强的相关性。基于细粗元素比，以及相对于主要元素浓度总和的单个元素百分比，可以在地面颗粒成分与反演柱气溶胶光学因子的日平均值之间建立简单的线性关系。该方法可用于建立一种从卫星柱状气溶胶光学测量数据中推导更大尺度地面气溶胶分布的检索算法。
The relationship between ground‐based particle chemical component and column aerosol optical property in dusty days over Beijing is analyzed. Typical element contained in particles either of Si, Fe, Ti, K, etc. shows a strong correlation with part column aerosol optical properties such as aerosol optical thickness, radiative forcing, and so on. Based on the fine‐to‐coarse elemental ratio, as well as the individual elemental percentage relative to the sum concentration of main elements, simple linear relationships can be established between the ground particle component and the daily averages of retrieved column aerosol optical factors. This method is available to establish a retrieval algorithm to derive the ground aerosol distribution on a larger scale from the column aerosol optical measurements of satellite.
