Nj. Mccormick, MATHEMATICAL-MODELS FOR THE MEAN COSINE OF IRRADIANCE AND THE DIFFUSEATTENUATION COEFFICIENT, Limnology and oceanography, 40(5), 1995, pp. 1013-1018
Equations to be used for fitting data for the mean cosine of irradianc
e and the diffuse attenuation coefficient are developed from radiative
transfer theory. Approximate models that have only a few parameters a
re developed and compared to those in the literature. A test is propos
ed for the validity of the model used with asymptotic closure theory f
or optical property estimation.
