Numerical Model for the Computation of Radiance Distributions in Natural Waters with Wind-Roughened Surfaces

摘要

The report is a repository of the details of derivation of a numerical procedure to determine the unpolarized radiance distribution as a function of depth, direction, and wavelength, in a natural hydrosol such as a lake or sea. The input to the model consists of (i) the incidence radiance distribution at the air-water surface, (ii) the state of randomness of the air-water surface as a function of wind speed, (iii) the volume scattering and volume attenuation functions of the medium as a function of depth and wavelength, and (iv) the type of bottom boundary. The model has an expandable library of derived quantities that are of use in various applications of optics to natural waters, such as marine biological studies, underwater visual search tasks, remote sensing, and climatology.
