Earth-Based Observations of the Galileo Probe Entry Site

Abstract

Earth-based observations of Jupiter indicate that the Galileo probe probably entered Jupiter's atmosphere just inside a region that has less cloud cover and drier conditions than more than 99 percent of the rest of the planet. The visual appearance of the clouds at the site was generally dark at longer wavelengths. The tropospheric and stratospheric temperature fields have a strong longitudinal wave structure that is expected to manifest itself in the vertical temperature profile.

We thank the staff of several observatories for their support in making a number of unusual but important changes to observing techniques and schedules. The mapping in Fig. 2A was kindly provided by A. Simon and R. Beebe. Our research was sponsored by various grants from NASA and NSF for work performed at each of the institutions with which we are associated.
