对数正态分布是一种在不同时空尺度下生物光学变化的有效模型。提出了一个参数统计框架，用于使用对数正态模型来评估异质性和规模对封闭的影响。小尺度的变异性影响大尺度的测量，但不能被大尺度测量所解决。假设的对数正态分布允许人们对小尺度的变异性进行积分，以预测大尺度的测量。举例说明如何将方差的知识纳入模型，以关联在不同尺度上进行的测量。
The lognormal distribution is presented as a useful model for bio-optical variability at a variety of spatial and temporal scales. A parametric statistical framework is presented for using the lognormal model to assess the effects of heterogeneity and scale on closure. Variability at small scales affects but is unresolved by large-scale measurements, An assumed lognormal distribution allows one to integrate over small-scale variability to predict large-scale measurements. Examples are presented to demonstrate how knowledge of the variance can be incorporated into models to relate measurements made at different scales.
