WebJun 11, 2024 · In physics, optical depth or optical thickness is the natural logarithm of the ratio of incident to transmitted radiant power through a material. Thus, the larger the optical depth, the smaller the amount of transmitted radiant power through the material. WebThe optical thickness of a cloud is the degree to which the cloud prevents light from passing through it. Optical thickness depends on the physical properties and the cloud dimensions. The observer should record the optical thickness, and indicate the direction in which the clouds or cloud layers have the greatest thickness.
