New determination of monochromatic methane absorption coefficients with regard to the thermal conditions in the atmospheres of giant planets. IV. Jupiter and Saturn

Abstract

Based on the data on the wavelength dependence of geometrical albedo for the disks of Jupiter and Saturn, we determined the trends in the height variation of the aerosol optical depth in the upper atmospheric layers of these planets, the fractional methane concentration in the Jovian atmosphere (0.00125), and the monochromatic methane absorption coefficients (or the superposition of these coefficients for methane and ammonia) typical of the thermal conditions in the atmospheres of Jupiter and Saturn in the wavelength range from 527 to 956 nm.
