摘要	数值模拟了在给定条件下气溶胶粒子群平均有效半径和折射率虚部不同时大气层顶的反射强度和到达地面的透射强度，以及不同气溶胶垂直分布对各高度层的反射、透射强度和辐照度的影响。结果表明，当大气气溶胶光学厚度相同时，气溶胶垂直分布对15km以下的反射和透射辐射影响较大；气溶胶粒子群平均有效半径和折射率虚部越小，大气层顶的反射强度和到达地面的透射强度越大。因此，对于准确地计算大气辐射不仅需要考虑气溶胶总光学厚度，还需考虑气溶胶粒子群的平均有效半径、复折射率和气溶胶垂直分布；计算中若只使用气溶胶模型中的经验值会带来较大误差。
其他摘要	Under the given condition, reflected intensity of the top of atmosphere and transmitted intensity arriving at the ground were simulated when aerosol particles average effective radius and complex refractive imaginary part index was different, as well as the effect of aerosol vertical distribution on reflection and transmission intensity and flux of different height. The result shows that when the aerosol optical thickness is fixed, the effect of aerosol vertical distribution on reflection and transmission is great under 15 km, and the smaller aerosol particles average effective radius and complex refractive index imaginary part of aerosol particles, then the larger reflected intensity of the top of atmosphere and transmitted intensity arriving at the ground. Therefore, in order to accurately calculate atmospheric radiation, not only the aerosol optical thickness but also aerosol particles average effective radius, complex refractive index and aerosol vertical distribution should be taken into consideration, and just using the empirical value of the aerosol model will bring bigger error.
