Some changes in the behavior with depth for the optical thicknesses of the aerosol and gas scattering components in profiles of λλ 887, 864, 842, 727, and 619 nm spectral absorption bands of atmospheric methane were studied. We examined the spectrophotometric data obtained from the measurements of the Jovian whole disk during 1993 and 1995. The aerosol scattering component increased by 0—5% (depending on the depth level) in 1995 as compared with 1993. Three different aerosol layers with gaps at the atmospheric levels near 0.38 and 0.52 bars were detected from the measurement data obtained in 1993. Some evidence of new aerosol layer formation at the atmospheric level with pressure from 15 to 18 bars in 1995 was revealed.
