I/F profile, plane parallel atmnosphere & phase functions

For our initial analysis, each high-phase-angle frame has been characterized by a single number--the maximum value of the normalized scattered intensity I/F along a radial scan (A normally illuminated, perfectly reflecting Lambert surface gives I/F = 1.) We have chosen to use only the maximum I/F value, because the shape of the intensity profile interior to the maximum I/F is almost totally insensitive to changes in the single-scattering phase function. The shape of the intensity profile is, however, sensitive to departures from plane parallel geometry, while our calculations show that the maximum I/F generally is not affected to any pronounced degree. \cite{Rages_1983}

Why Single Scattering prop. important

Measurements of the size and shape of the particles permit thesingle scattering, and thus multiple scattering of solar radiation in the atmosphere to be modeled. Such models are necessary to cre- ate models of the radiative net fluxes and the profiles of solar heat- ing in the atmosphere to give the radiative forcing for atmospheric dynamics.

Fig21. The shapes of the single-scattering intensity phase functions used for the blue models. The peaks for scattering angles less than 9° are from the appendix of Tomasko et al. (2008) while the curves for angles greater than 9° are smoothly mated to the Henyey–Greenstein functions used in Tomasko et al. (2008) to fit the blue Solar Aureole measurements at a wide range of angles from the Sun.
