Proposal Summary:
The primary goal of this program is to determine the temperature field in Jupiter's upper troposphere from filtered radiometric measurements made by the Galileo Photopolarimeter Radiometer (PPR) experiment during the Galileo Europa Mission (GEM). These temperature fields will then be used to determine the vertical wind shear for at least one level of the atmosphere. A secondary goal is to archive high-level data products, the processed radiance maps, with the Planetary Data System. The results of the proposed research are intended to complete as far as possible the analysis of PPR filtered radiometric measurements obtained during GEM. The regions that were or will be mapped during GEM orbits 16, 17, 20, 22 and 24 included major sections of the North and South Equatorial Belts. These contained unusual thermal waves that appeared unrelated to the cloud albedo morphology, as well as local structure that appeared to be more correlated with the cloud morphology. Discrete features were also mapped, including the white oval "BE" 5 months after the merging of the original white ovals BC and DE, unusually dark spots that appear to be isolated cyclonic regions, the Great Red Spot, and a region of turbulent flow to the northwest of the GRS. The funding of the GEM phase of the Galileo mission was adequate for planning and execution of PPR observations, but little was left for the requisite reduction or for analysis. Consequently, the proposed work represents our first opportunity to analysze these data in quantitative detail. Preliminary analysis of some these data was reported by Orton et al.(1998) Bull. Amer. Astron. Soc. 30, 1074.
