, 2008: Photopolarimetry of planetary atmospheres: What observational data are essential for a unique retrieval of aerosol microphysics? Mon. Not. Roy. Astron. Soc., 384, 64-70, doi:10.1111/j.1365-2966.2007.12679.x.We analyse the results of computations of the intensity and degree of linear polarization of diffusely reflected sunlight for the centre of a planetary disc in the phase-angle range 0° < α < 90°. The computations are performed using numerically exact T-matrix and vector radiative-transfer codes for several alternative models of the Jovian cloud layer derived previously from ground-based spectropolarimetric observations at phase angles α < 11°. Our results show that although these models reproduce the existing observational data equally well, they start to show significant polarization differences at phase angles α ≥ 12°. Thus, using Jupiter as a "proving ground", we conclude that only polarimetric data obtained over a wide range of phase angles (i.e. from spacecraft) may provide definitive constraints on aerosol shape and, as a consequence, ameliorate the ill-posed nature of the inverse remote-sensing problem.
