Comparison of Numerical Models for Computing Underwater Light Fields

摘要

This report documents the efforts of nearly all of the active optical modelers ofthe world to establish a standard set of optical input parameters and of radiant flux outputs to be expected in a hydrosol that exhibits these optical parameters. I contributed output from the NRL optical model (Monte Carlo) for comparisons of output for molecular water, a standard hydrosol scattering function, and the contribution of water Raman scattering. Optical energy trapping near the water/air interface was verified. In addition, effects of a simple model of skylight radiance and marine aerosols were investigated. The results of the simple skylight model were in accord with the results of more complex layered models of the atmosphere. The long term goal of this study and collaboration is to establish a standard optical model of the ocean. Ocean optical models, Water Raman scattering, Optical energy trapping.
