大气气溶胶特性包括气溶胶的物理、化学、光学特性，而气溶胶光学参数的确定是准确估算辐射强迫的前提条件。提出一种结合大气辐射传输模型，利用查表法反演气溶胶消光的方法，研究了单次散射反照率、非对称因子及地表反照率等输入参数对模拟氧的二聚体（O4）大气质量因子的影响。利用多轴差分吸收光谱(MAX-DOAS)技术在不同仰角下进行测量，将计算得到的O4的大气质量因子与辐射传输模型计算的大气质量因子做比较，通过最小化及线性插值过程反演出气溶胶的光学厚度、边界层高度及地面消光系数。建立查找表，以上海宝山监测点多轴差分吸收光谱仪测量为例，反演出气溶胶的消光，并与雷达监测数据做对比，两者具有较好的一致性。结果表明，查表法可以实现气溶胶特性的探测。

The properties of aerosol include physical, chemical and optical characteristics. Whiles the determinant of optical parameters is the prerequisite for accurate estimation to the radiation forcing. A method for determining aerosol extinction with look-up table is presented combined with radiative transfer model. Also the effects of single scatter albedo rate, asymmetry parameter and ground albedo rate on the simulation of O4 air mass factor are studied. Using O4 air mass factor based on multi-axis differental optical absorption spectroscopy (MAX-DOAS) measurement at different elevation angles, simulated O4 air mass factor and the factor got through the radiative transfer model are compared. The aerosol optical density, boundary height and extinction coeffcient are retrieved after the process of minimization and linearly interpolation. Creating a look-up table, the aerosol extinction is determined at Shanghai Baoshan monitoring site using MAX-DOAS. Compared with lidar, it shows a reasonable agreement. It′s turned out that the look-up table can be used to detect the properties of aerosol.
