Temporal Variations of Jupiter's Plasma Disk Observed by Juno

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In Jupiter's magnetosphere, a key question is how plasma is transported outward from its source near Io to the distant magnetotail. Since 2016, the plasma disk has been extensively observed by the Juno mission. Using plasma data from the JADE instrument, we perform an analysis revealing significant temporal variation. For different Juno orbits,

Sporadic E-like Topside Layer Driven by Wind Shear in the Martian Ionosphere

The Astrophysical Journal
Ionospheric plasma density disturbances significantly affect radio wave propagation, impacting communication and planetary exploration. At Earth, sporadic E layers (Es) are commonly observed. They are characterized by thin, high-density plasma structures

Excitation of planetary electromagnetic waves in the inhomogeneous ionosphere [PDF]

Annales Geophysicae, 2014
Abstract. In this paper we develop a new method for the analysis of excitation and propagation of planetary electromagnetic waves (PEMW) in the ionosphere of the Earth. The nonlinear system of equations for PEMW, valid for any height, from D to F regions, including intermediate altitudes between D and E and between E and F regions, is derived.

Unprecedented Extreme Dust Storm Triggered by Stratosphere‐Troposphere Interactions

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract An unprecedented dust storm struck southern China in April 2025, affecting hundreds of millions of people in regions rarely impacted by dust storms and challenging existing understanding of lower‐latitude dust storms. Here, we show that polar stratospheric signals enabled this event by modulating tropospheric teleconnection, revealing an ...

Ionospheres and atmospheres of non-magnetic planets and solar wind interaction: Part I – Venus [PDF]

, 2002
349-356The solar-planetary interaction is unique for non-magnetic planets, since the solar wind interacts directly with the atmospheres and ionospheres of these planets.

Solar activity variations of the ionospheres of Venus and Mars [PDF]

, 2021
Extreme ultraviolet and X-ray photons from the Sun generate a partially ionized region in the atmosphere of a planet called an ionosphere. Solar activity, including solar flares, coronal mass ejections, and changes in the ionizing irradiance affect ...

TRACERS Small‐Scale Field‐Aligned Currents and Intense GPS Amplitude and Phase Scintillations in the Nightside Auroral Region

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We present conjugate observations of ionospheric small‐scale magnetic perturbations (dB) $(dB)$ and GPS scintillations from the Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) and the Canadian High Arctic Ionospheric Network (CHAIN) during a storm‐time substorm on 9 August 2025 in the nightside auroral region ...

A Study of the reactions of Al⁺ ions with O₃, N₂, O₂, CO₂ and H₂O: influence on Al⁺ chemistry in planetary ionospheres [PDF]

, 2019
The reactions between Al+(31S) and O3, O2, N2, CO2 and H2O were studied using the pulsed laser ablation at 532 nm of an aluminium metal target in a fast flow tube, with mass spectrometric detection of Al+ and AlO+.

Magnetic Reconnection inside a Martian Ion Plume: MAVEN Observations

The Astrophysical Journal
The Martian ion plume is an important escape channel that influences the long-term evolution of the planet’s atmosphere, yet the small-scale dynamics within plumes remain poorly constrained by in situ observations.

Pre‐Existing Plasmaspheric Density Structure

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We perform a basic model experiment: we run two nearly identical plasmapause simulations, differing only by their initial conditions. The first run contains initial fine‐scale and mesoscale structure, and the second run is initialized with a featureless, circular plasmapause.
