Interpretation of hydrogen quadrupole and methane observationsof Jupiter and the radiative properties of the visible clouds
We describe the most detailed and physically realistic analysis yet of the published observations of the hydrogen quadrupole lines and the R-braneh of the 3 va CFI4 band within the framework of our present understanding of the physical processes involved. The results give a self-consistent model for the structure composition of the Jovian atmosphere and the radiative properties of the visible clouds at the centre of the disc. The visible clouds are represented by two distinct layers; a thin layer in the upper troposphere and a dense cloud whose top is at 2 atm level. This analysis suggests that for these observations the upper cloud is optically thin at visible wavelengths characterized by an isotropic optical thickness of fl* = I 5- and an isotropic single scattering albedo of Wl* = . The results also indicate mixing ratios for the main constituents of H2:He = 6:i and CH4/H2 = (71') X I0- .
