| 摘 要： | 在卫星遥感中, 利用单次散射近似获得双向反射比与光学厚度之间的关系为卫 星反演气溶胶光学厚度奠定基础. 本文利用渐近积分理论, 在不需要人为垂直分层的情况下, 基于单次散射近似, 提出了一种计算非均质大气的双向反射比的新方法. 结果表明: 新方法得到的解析表达式有非常高的精度, 且该解析解也有助于我们分析辐射传输过程的一些重要特征. |

| Abstract: | In satellite remote sensing, the relationship between bidirectional reflectance and optical depth is the foundation of the retrieval of the aerosols' optical depth. According to asymptotic integral theory, a new approach to dealing with bidirectional reflectance of atmospheric without artificial stratification in the single-scattering approximation. The results show that the accuracy of analytical solution obtained by the new method is high. We formulate the analytical bidirectional reflectance with the vertical continuity of the inherent optical properties. Moreover, analytical solution is relatively easy to explain some of most import features for radiative transfer process. |
| Keywords: | radiative transfer asymptotic integration bidirectional reflectance |
