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 are not detected. In this way we obtained 231 profiles of peak electron densities that cover all Saturnian… 
Planetary Period Oscillations of Saturn’s Dayside Equatorial Ionospheric Electron Density Observed on Cassini’s Proximal Passes
We examine electron density data obtained in Saturn’s dayside equatorial ionosphere during Cassini’s proximal periapsis passes, specifically data derived from wave spectra, for evidence of modulation
Electron Density Distributions in Saturn's Ionosphere
Between 26 April and 15 September 2017, Cassini executed 23 highly inclined Grand Finale orbits through a new frontier for space exploration, the narrow region between Saturn and the D Ring,
Saturn's Ionosphere: Electron Density Altitude Profiles and D‐Ring Interaction From The Cassini Grand Finale
We present the electron density (ne) altitude profiles of Saturn's ionosphere at near‐equatorial latitudes from all 23 orbits of Cassini's Grand Finale. The data are collected by the Langmuir probe
A giant thunderstorm on Saturn
Observations of a giant thunderstorm at planetocentric latitude 35° north that reached a latitudinal extension of 10,000 kilometres about three weeks after it started in early December 2010, which developed an elongated eastward tail with additional but weaker storm cells that wrapped around the whole planet by February 2011.
Saturn’s near-equatorial ionospheric conductivities from in situ measurements
The Pedersen and Hall conductivities are presented, and a temporal variation (decrease) of the plasma densities, mean ion masses and consequently the conductivities from orbit 288 to 292 are suggested.
Hydrocarbon ions in the lower ionosphere of Saturn
Radio occultation measurements of the Saturn ionosphere have shown that persistent but variable electron density layers appear well below the major peaks. We model here the region of hydrocarbon ions
In situ measurements of Saturn’s ionosphere show that it is dynamic and interacts with the rings
Examination of plasma data collected in situ at Saturn found that Saturn's ionosphere is highly variable and interacts with the planet's inner ring, and decreases in ionization within regions shaded from the Sun by the rings.


Saturn's ionosphere: Inferred electron densities
During the two Voyager encounters with Saturn, radio bursts were detected which appear to have originated from atmospheric lightning storms. Although these bursts generally extended over frequencies
Effects of ring shadowing on the detection of electrostatic discharges at Saturn
A long‐standing discrepancy exists in determinations from observations and modeling of the diurnal variation of the peak electron density of Saturn's ionosphere. Using a new
A simple scale height model of the electron density in Saturn's plasma disk
A study of electron densities in Saturn's inner magnetosphere is presented using measurements of the upper hybrid resonance frequency obtained from the Radio and Plasma Wave Science (RPWS) instrument
Voyager electron density measurements on Saturn: Analysis with a time dependent ionospheric model
We have used a one-dimensional chemical diffusive model of the ionosphere, in conjunction with the measured Voyager ultraviolet spectrometer (UVS) upper atmospheric temperature and composition
Cassini radio occultations of Saturn's ionosphere: Model comparisons using a constant water flux
Recent radio occultations of Saturn's equatorial ionosphere by the Cassini spacecraft provide important insight into this poorly constrained region. Twelve new electron density profiles identify a
Atmospheric storm explanation of saturnian electrostatic discharges
The Voyager Planetary Radio Astronomy (PRA) experiments detected an impulsive (15–400 ms), broadband (20 kHz to 40 MHz) radio emission component that persisted throughout the two Saturn encounter
First results from the ionospheric radio occultations of Saturn by the Cassini spacecraft
[1] The first set of near-equatorial occultations of the Saturn ionosphere was obtained by the Cassini spacecraft between May and September of 2005. The occultations occurred at near-equatorial
Detection of visible lightning on Saturn
Until now, evidence for lightning on Saturn has been indirect – through radio emissions and cloud morphology. Here we report the first visible detection of lightning, on the night side on August 17,
New model of Saturn's ionosphere with an influx of water from the rings
Current theoretical models of Saturn's ionosphere are similar to those of Jupiter's because of the gross similarity of their upper atmospheres. In the case of Jupiter, the theoretical models can be
