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.

土星北半球纬向带气溶胶折光率虚部的值比较

使用2015年的分光光度测量数据，确定了土星圆盘的纬向带17°N，33°N，49°N和66°N的气溶胶折射率的虚部n _i的值之间的关系。从圆盘的赤道区域向北移动到北纬49°N（含端点）时，相对n _i值呈稳定下降的趋势。发现在17°N和49°N带中的n _i值与巨型行星盘的其他纬度区域显着不同。
