Geophysical Research Letters, 1996 A novel method is described for reconstruction of two‐dimensional current‐layer structures from measurements taken by a single spacecraft traversing the layer. In its present form, the method is applicable only to 2D magneto‐hydrostatic structures that are passively convected past the observing spacecraft. It is tested on a magnetopause crossing of the

Assessment of Spacecraft Internal Charging in the Earth's Outer Radiation Belt
Space Weather, Volume 24, Issue 8, August 2026.Abstract The internal charging effects triggered by energetic (>100 keV) electrons in the Earth's radiation belts can cause anomalies and failures of electronic components aboard spacecraft. Given the critical importance of safeguarding space assets, it is essential to estimate internal charging risks, which depend highly on the distribution of ...

Geophysical Research Letters, 2021 The magnetopause marks the outer edge of the Earth's magnetosphere and a distinct boundary between solar wind and magnetospheric plasma populations. In this study, we use global magnetohydrodynamic simulations to examine the response of the terrestrial ...

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.

Quantifying Uncertainty in OMNI Solar Wind Measurements Projected From L1 to the Earth's Bow Shock
Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract Many routine measurements of the solar wind plasma and interplanetary magnetic field (IMF) are made at the L1 Sun–Earth Lagrange point; therefore, it is helpful to characterize the errors introduced in propagating these measurements to the near‐Earth environment.

Coincident ENA and Narrowband Radio Emissions as Diagnostics of Inward Plasma Transport at Saturn
Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract Saturn's kilometric radiation (SKR) and Energetic Neutral Atom (ENA) emissions are important diagnostics of the planet's magnetospheric dynamics, intensifying during global plasma injections and displaying characteristic planetary periodicity. Related to the SKR emissions are myriametric narrowband radio emissions that typically appear in the ...

Possible configurations of the magnetic field in the outer magnetosphere during geomagnetic polarity reversals [PDF]
Annales Geophysicae, 2000 Possible configurations of the magnetic field in the outer magnetosphere during geomagnetic polarity reversals are investigated by considering the idealized problem of a magnetic multipole of order m and degree n located at the centre of a spherical ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract We investigated the spatial distributions and pitch‐angle distributions of 30–300 eV H+ and O+ ion fluxes using data obtained by the low‐energy particle experiments‐ion mass analyzer (LEPi) onboard the Arase satellite. A statistical analysis over 3.7 years reveals that the H+ ion flux is enhanced at L > 4 from the premidnight sector through ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract The Cassini spacecraft spent 13 years orbiting Saturn, quasi‐continuously measuring Saturn's radio emissions. One of the key elements of the radio spectrum at Saturn is the Saturn Kilometric Radiation (SKR), and several studies have been written on events called Low Frequency Extensions (LFEs) which represent strong, continuous extensions of ...

Alfvénic Poynting Flux Characterized by a Substorm‐SMC Cycle and Ionospheric Influence
Space Weather, Volume 24, Issue 8, August 2026.Abstract Geomagnetic substorms are fundamental processes of explosive geospace energy release within the Earth's magnetotail, which are usually divided into three phases: the growth phase, the expansion phase, and the recovery phase. Large‐scale electromagnetic energy transport during a geomagnetic substorm is in the form of Alfvén waves, transmitting ...
