Rayleigh optical depth

The optical depth of the atmosphere can be divided into several components, ascribed to Rayleigh scattering, aerosols, and gaseous absorption. The optical depth of the atmosphere can be measured with a sun photometer. The optical depth with respect to the height within the atmosphere is given by See more 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 … See more Attenuation Optical depth measures the attenuation of the transmitted radiant power in a material.
