A new model for plasmapause locations derived from IMAGE RPI and Van Allen Probes data

Journal of Space Weather and Space Climate
The outer boundary of the plasmasphere, the plasmapause, is characterized by a sharp electron density gradient that changes under varying space weather conditions.

Correlations between plasmapause evolutions and auroral signatures during substorms observed by Chang’e-3 EUV Camera

Earth and Planetary Physics, 2017
The plasmapause locations determined from the Chang’e-3 (CE-3) Extreme Ultraviolet Camera (EUVC) images and the auroral boundaries determined from the Defense Meteorological Satellite Program (DMSP) Special Sensor Ultraviolet Spectrographic Imager (SSUSI)

Cluster observations of mid-latitude hiss near the plasmapause [PDF]

Annales Geophysicae, 2004
In the vicinity of the plasmapause, around the geomagnetic equator, the four Cluster satellites often observe banded hiss-like electromagnetic emissions (BHE); below the electron gyrofrequency but above the lower hybrid resonance, from 2kHz to 10kHz ...

A Statistical Study of Warm Plasma Cloak Particles Using Van Allen Probe Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The Warm Plasma Cloak (WPC) consists of ions in the inner magnetosphere with energies between 10 eV and 1 keV and showing a bidirectional pitch angle distribution of particles. These particles play an important role in wave–particle interactions and in controlling the dayside reconnection rate at the magnetopause.

Wave and plasma measurements and GPS diagnostics of the main ionospheric trough as a hybrid method used for Space Weather purposes [PDF]

Annales Geophysicae, 2008
The region of the main ionospheric trough is a unique region of the ionosphere, where different types of waves and instabilities can be generated. This region of the ionosphere acts like a lens, focusing a variety of indicators from the equator of ...

Global Effect of Long‐Lasting 07–12 October 2024 Geomagnetic Storms During the Transition From a Strong (G3) to a Severe (G4) on the Geomagnetic Field and Ionospheric Parameters Distribution

Space Weather, Volume 24, Issue 7, July 2026.
Abstract This study investigates the co‐evolution of geomagnetic field disturbances with ionospheric parameters and their characteristic latitudinal signatures by conducting a location and time‐dependent analysis of the 07–12 October 2024 events, to fill crucial gaps in understanding the coupled response of the magnetosphere‐ionosphere system. This has

Global estimates of plasmaspheric losses during moderate disturbance intervals [PDF]

Annales Geophysicae, 2010
For a set of five moderate disturbance events, we calculate the total number of He+ ions removed the plasmasphere using calibrated global EUV images.

Observing the Earth's Plasmasphere and Ionosphere From the Lunar Surface

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We present the analysis of the first lunar‐based observational characterization of the Earth's plasmasphere and ionosphere using Global Navigation Satellite Systems signals tracked from the lunar surface by the Lunar GNSS Receiver Experiment (LuGRE). The Earth‐Moon geometry enables limb sounding of the plasmasphere at altitudes exceeding 3,000

Spatio-temporal structure of a poloidal Alfvén wave detected by Cluster adjacent to the dayside plasmapause [PDF]

Annales Geophysicae, 2008
A case study of a poloidal ULF pulsation near the dayside plasmapause is presented based on Cluster observations of magnetic and electric fields. The pulsation is detected close to the magnetic equatorial plane at L shells L=[4.4, 4.6] and oscillates

Electron Scattering by Highly Oblique Quasi‐Electrostatic Chorus Waves Under Realistic Magnetospheric Conditions

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Using Van Allen Probes data (2013–2015), we report that highly oblique chorus waves frequently occur in low‐density regions where fpe/fce≈3 ${f}_{\text{pe}}/{f}_{\text{ce}}\approx 3$. These waves exhibit an electric‐to‐magnetic energy ratio PE/c2PB>0.5 $\sqrt{{P}_{\mathrm{E}}/{c}^{2}{P}_{\mathrm{B}}} > 0.5$, much higher than the typical <0.1 ${
