Abstract
Using the spectrophotometric measurements data of 2015, the relation of values of the imaginary part n i of aerosol refractive index was determined for latitudinal belts 17° N, 33° N, 49° N, and 66° N of Saturn’s disc. A steadily decreasing tendency in the relative n i values when moving northward from the equatorial region of the disk to the latitude 49° N, inclusive, was revealed. The n i values in the 17° N and 49° N belts were found to differ significantly from other latitudinal regions of the giant planet’s disk.
