# Saturn's Ionosphere

## TL;DR

This paper reviews current knowledge of Saturn's ionosphere, emphasizing new data from Cassini, recent ground-based observations, and discusses model-data discrepancies to guide future research.

## Contribution

It provides a comprehensive overview of Saturn's ionosphere, highlighting recent discoveries and identifying gaps between models and observations to inform future studies.

## Key findings

- Cassini data significantly increased electron density profiles.
- Detection of 'ring rain' effects on Saturn's ionosphere.
- Current models show discrepancies with observations.

## Abstract

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 detection of the effect of "ring rain" on Saturn's ionosphere, and present possible model interpretations of the observations. Finally, we outline current model-data discrepancies and indicate how future observations can help in advancing our understanding of the various controlling physical and chemical processes.
