Abstract

The structure of the Jovian stratosphere at the Galileo probe entry site is investigated through calculations of radiative heating rates based on measurements of the temperature profile, composition, and aerosol distribution. From analysis of mid-IR observations of Jupiter, we determine a C₂H₂ mole fraction of 1.1-4.3 × 10^-6 at 0.01 mbar, and a C₂H₆ mole fraction of 2.8-6.5 × 10^-6 at 0.4-10 mbar. The derived distributions imply that C₂H₆ and C₂H₂ are the most important coolants in the Jovian stratosphere from 0.004 to 10 mbar, and that the stratosphere is close to radiative equilibrium. In Jupiter's stratosphere, as in the stratosphere of the Earth, photochemical species play an essential role in the energy balance.
