The effective temperature of Jupiter'S equatorial belt during the 1965 apparition

Abstract

Preliminary results from our study of Jupiter's equatorial limb darkening at 8–14 μ indicate that the effective temperature of the equatorial belt lay between 140 K and 150 K. We find these temperatures to be insensitive to the likely range of the He/H2 ratios. These results assume that Jupiter's only significant sources of extinction at these wavelengths are the pressure-induced absorption of H2 and He and the absorption of saturated NH3.
