A Comparison of Values of the Imaginary Part of Aerosol Refractive Index in the Latitudinal Belts of Saturn’s Northern Hemisphere

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.
