Abstract
A simple expression is obtained for the irradiance reflectance of the ocean based on a two-flow radiative transfer model. This expression is found to reproduce the Monte Carlo calculations to within 7% for scattering albedo values less than 0.8. On the basis of this expression, it is shown that the remotely sensed water color data can be interpreted with the help of iterative optimization techniques, provided that the variations of backscattering coefficient and absorption coefficient with wavelength can be modeled.
