Abstract

A one-parameter two-term Henyey-Greenstein (TTHG) phase function of light scattering in seawater is proposed. The original three-parameter TTHG phase function was reduced to the one-parameter TTHG phase function by use of experimentally derived regression dependencies between integral parameters of the marine phase functions. An approach to calculate a diffuse attenuation coefficient in the depth of seawater is presented.

  9. The regressions in Eqs. (11) and (12) are custom-made regressions. They were derived manually and nonformally by the trial and error method. The original regressions given in Ref. 8 are valid in the range of experimental measurements 0.05 ≤ B ≤ 0.25. The full range of variability of backscattering probability B = bb/b is between 0 (highly anisotropic delta-shaped in forward-direction scattering) and 0.5 (isotropic scattering). The original experimental data by Timofeyeva, who is regarded as one of the top experimentalists in hydrological optics of the 1960s and 1970s, were recovered from the scan of the figure published in Ref. 8 and checked with the original nonphysical regressions. I obtained the new regressions manually by forcing them to obey both the experimental points and the physical requirements listed above.
