From the angular positions of the glory features observed on the upper cloud deck of Venus in three VMC channels (at 0.365, 0.513, and 0.965 mkm), the dominating sizes of cloud particles and their refractive index have been retrieved, and their spatial (in latitude) and temporal (in local time) variations have been analyzed. For this, the phase profiles of brightness were compared to the singe-scattering phase functions of particles of different sizes. [mehr]
