Abstract

The purpose of this research is to study the effect of nonuniform vertical profiles of chlorophyll concentration on apparent optical properties with Radiative transfer model Hydrolight. The vertical profiles of chlorophyll concentration were approximated according to a Gaussian function(Lewis et al, 1983).The simulated AOPs for nonuniform chlorophyll profiles were compared with those for homogenous ocean whose chlorophyll concentration was identical to the background chlorophyll concentration of inhomogenous cases. The results reveal that the subsurface maximal chlorophyll concentration increase remote sensing reflectance in the blue wavelength and decrease it in the green wavelength, and nonuniform vertical profiles of chlorophyll concentration change the diffuse attenuation coefficient profiles and the angular structure of the light field in the seawater.
