8 Saturn ’ s Ionosphere
This chapter summarizes our current understanding of the ionosphere of Saturn. We give an overview of Saturn ionospheric science from the Voyager era to the present, with a focus on the wealth of new data and discoveries enabled by Cassini, including a massive increase in the number of electron density altitude profiles. We discuss recent ground-based detections of the effect of “ring rain” on ...
متن کاملSaturn: atmosphere, ionosphere, and magnetosphere.
The Cassini spacecraft has been in orbit around Saturn since 30 June 2004, yielding a wealth of data about the Saturn system. This review focuses on the atmosphere and magnetosphere and briefly outlines the state of our knowledge after the Cassini prime mission. The mission has addressed a host of fundamental questions: What processes control the physics, chemistry, and dynamics of the atmosphe...
متن کاملUpper Atmosphere and Ionosphere of Saturn
This chapter summarizes our current understanding of the upper atmosphere and ionosphere of Saturn. We summarize the available observations and the various relevant models associated with these regions. We describe what is currently known, outline any controversies and indicate how future observations can help in advancing our understanding of the various controlling physical and chemical proce...
متن کاملThe Ionosphere of Saturn Predictions for Pioneer 11
Model calculations indicate that the lower ionosphere of Saturn is controlled by photochemical processes, with basic features similar to the Jovian ionosphere. The scale height of the upper ionosphere is large (•3350 km). A peak electron density of •10•cm -s 2250 km above a 10•9cm -a reference level is expected assuming an eddy coefficient at the homopause of 1.3 x 10øcmas -• and a relatively h...
متن کاملPeak electron densities in Saturn’s ionosphere derived from the low‐frequency cutoff of Saturn lightning
[1] Radio bursts from Saturn lightning have been observed by the Cassini Radio and Plasma Wave Science instrument at frequencies of a few megahertz during several month‐long storms since 2004. As the radio waves traverse Saturn’s ionosphere on their way to the spacecraft, one can determine the peak electron density from the measurement of the low‐frequency cutoff below which the radio bursts ar...
