A simple inversion technique in the single scattering regime has been developed to deduce cloud droplet size parameters by using the measurement of the radiance of near-forward scattered solar radiation as a function of angle. Compared with the numerical inversion technique that uses exact Mie scattering calculations, the new technique is much less time-consuming and hence should be usable in an on-line real time analysis. To test the effectiveness of the new technique, we use the results of polydispersed cloud size distribution calculated by Deirmendjian to retrieve the model size parameters. The agreement is excellent. We also generalize the theory to include the broadband source. A typical experimental example is given. Its comparison with time-consuming Mie scattering inversion technique again shows excellent agreement.
已开发出一种单散射 regime 中的简单反演技术，通过测量近前向散射太阳辐射的辐射亮度随角度的变化来推导云滴大小参数。与使用精确米氏散射计算的数值反演技术相比，新技术耗时少得多，因此应可用于在线实时分析。为测试新技术的有效性，我们使用 Deirmendjian 计算的多分散云大小分布结果来反演模型大小参数。一致性非常好。我们还将该理论推广到包括宽带源的情况。给出了一个典型的实验示例。它与耗时的米氏散射反演技术的比较再次显示出非常好的一致性。
