About Nonlinear Dependence of Remote Sensing and Diffuse Reflection Coefficients on Gordon's Parameter

Remote sensing i and diffuse reflection R coefficients of seawater are dependent on inherent optical properties of seawater through the Gordon's parameter bB / (a bB), where a is an absorption and b is backscattering coefficients. g=+B Majority of researchers in ocean optics use linear approximation for and R, i. e. g and R oc g. This approach works well when g 0.1. All open and largest art of coastal waters satisfy this condition, but there are some cases when parameter g is as large as 0.98. We illustrate this fact with histogram of Gordon's parameter g for the Yellow sea waters. We present a choice of alternative rigorous nonlinear equations for R that solve this problem, i.e. significantly reduce the error of the restoration of the Gordon's parameter g from remote sensing optical data and estimate possible errors in using linear dependencies.
