Generation of Falling‐Tone Whistler‐Mode Chorus Waves in the Earth's Magnetosphere

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Chorus waves are intense whistler‐mode emissions in space that play a key role in regulating energetic electron dynamics in the hazardous radiation belt. While rising‐tone chorus has been extensively studied, the generation mechanism of falling‐tone chorus remains a long‐standing problem.

Ionic reactions in the laboratory and in planetary atmospheres [PDF]

, 1979
A detailed understanding of the ionospheres of the Earth and planets requires knowledge of the rates of many ionic reactions as well as of electron recombination coefficients and photoionization cross sections.

Derivation of a planetary ionospheric storm index [PDF]

Annales Geophysicae, 2008
Abstract. The planetary ionospheric storm index, Wp, is deduced from the numerical global ionospheric GPS-IONEX maps of the vertical total electron content, TEC, for more than half a solar cycle, 1999–2008. The TEC values are extracted from the 600 grid points of the map at latitudes 60° N to 60° S with a step of 5° and longitudes 0° to 345° E with a ...

Discrete Energy Bands Beyond Galilean Moons: Bounce‐Phase Structuring of Jovian Magnetospheric Particles

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Discrete energy bands of ion fluxes, typically organized in velocity with equal separations, have been frequently observed in Jupiter's magnetosphere either in association with Galilean moons or in regions far from their influence. Here, we focus on the latter type and propose that these bands are manifestations of bounce‐phase structuring ...

Current Events at Saturn: Ring–Planet Electromagnetic Coupling

The Planetary Science Journal
This study presents a synthesized analysis of in situ and ground-based observations to investigate electromagnetic coupling between Saturn and its rings. During the Cassini Grand Finale, the magnetometer detected gradients in the azimuthal magnetic field

Excitation of Large Amplitude Compressional ULF Waves in the Magnetosphere by Solar Wind Pressure Spikes and IMF Southward Turning

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We present a case study of large amplitude, compressional Pc5 waves observed by GOES 13 and 15 at geosynchronous orbit near noon. These waves were excited near the arrival time of two consecutive solar wind dynamic pressure spikes at the magnetopause, the second of which was associated with a large and rapid southward turning of the ...

Photoelectrons as a Tracer of Planetary Atmospheric Composition: Application to CO on Mars [PDF]

, 2020
Photoelectrons are an extensively studied component of planetary ionospheres which have been frequently used as a diagnostic of ambient magnetic fields. We show in this study that they also provide information on atmospheric composition via the altitude ...

Independent Component Analysis (ICA) as a Superior Atmospheric Correction Method for InSAR Time Series

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Satellites such as the European Space Agency's Sentinel‐1 constellation allow for the creation of unprecedented volumes of Interferometric Synthetic Aperture RaDAR data that contains both deformation and atmospheric signals. Correction methods have been developed to reduce these atmospheric signals, but they do not generally perform well on ...

Experimental Study of the Response of Sheared E × B Flow to Varying Ion–Neutral Collisions

The Astrophysical Journal, 2023
Partially ionized plasma is a common occurrence in astrophysical and space environments. The emergence and development of plasma instabilities are significantly impacted by the inelastic collisions between the ions and neutrals in the partially ionized ...

Bidirectional Energy Transfer via Simultaneous Wave‐Particle Resonances in Inhomogeneous Space Plasmas

AGU Advances, Volume 7, Issue 4, August 2026.
Abstract Wave‐particle resonance is a key mechanism for energy transfer in collisionless plasmas with important implications for wave excitation and particle acceleration. Cyclotron resonance occurs when a particle's gyromotion synchronizes with the wave fields, with their interactions usually describable by quasilinear diffusion or nonlinear trapping.
