The optical depth of a settling aerosol is measured as a function of time. An analytic model is fitted to the time record of the optical depth. This allows an inversion of the problem which results in an analytic model for the size distribution of aerosol particles for radii between 1 micro and 10 micro. The model size distribution is verified by comparison with data from a direct microscope count of particle sizes. The model size distribution is then used to calculate the time behavior of forward scattered light. This calculation is compared to experiment to provide further corroboration of the aerosol size distribution.
沉降气溶胶的光学厚度作为时间的函数进行测量。将一个解析模型拟合到光学厚度的时间记录上。这使得问题能够进行反演，从而得到半径在1微米至10微米之间的气溶胶粒子尺寸分布的解析模型。通过与直接显微镜粒径计数数据进行比较，对模型尺寸分布进行验证。然后使用模型尺寸分布来计算前向散射光的时间行为。将该计算结果与实验进行比较，以进一步证实气溶胶的尺寸分布。
