Multi‐Species Energy‐Banded Ions in the Ionosphere During the 21 January 2005 Magnetic Storm: Low‐Altitude Edge of the Warm Plasma Cloak

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract During the 21–22 January 2005 magnetic storm, the FAST satellite observed warm (< few keV) ions in discrete energy bands on the dayside at ∼3,000 km altitude for more than 6.5 hr. We suggest that the ionospheric energy‐banded ions represent the low‐altitude edge of the warm plasma cloak observed simultaneously by magnetospheric satellites ...

The structure of field line resonances in a dipole magnetosphere with moving plasma [PDF]

Annales Geophysicae, 2008
A theoretical model of field line resonance in the magnetosphere with a dipole magnetic field and moving plasma was constructed. Motion of medium was simulated by its azimuthal rotation.

Outer Radiation Belt Dynamics During the October 2012 Storm Revisited: Rapid Inward Radial Transport From a Dynamic Outer Boundary

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Earth's outer radiation belt electron flux is highly variable and can be enhanced by over an order of magnitude over timescales less than one day, as observed during the October 2012 storm. Previous studies of this storm (e.g., Reeves et al., 2013, https://doi.org/10.1126/science.1237743) have invoked local acceleration to explain this ...

An alternative interpretation of Jupiter's “plasmapause”

Geophysical Research Letters, 1976
It has recently been suggested that Io is an important source of ions for the plasma detected by Pioneer 10 in the inner magnetosphere of Jupiter. Assuming this to be true, we show that near the orbit of Io the central collector of the Pioneer‐10 plasma instrument could detect only inwardly diffusing ions created at a radial distance greater than that ...

Derivation of Ambient Electron Density Using Spacecraft Potential Measurements From the MMS and Van Allen Satellites: Application to the Plasmasphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract We investigate the empirical relationship between the spacecraft potential (Vs) measured by the Electric Field Double Probes, and the electron density (Ne) measured by the Fast Plasma Instrument on the MMS spacecraft. We derive their relationship during fast‐mode intervals when the Active Spacecraft Potential Control Devices are off.

Investigation of EMIC wave scattering as the cause for the BARREL 17 January 2013 relativistic electron precipitation event: A quantitative comparison of simulation with observations [PDF]

, 2014
Electromagnetic ion cyclotron (EMIC) waves were observed at multiple observatory locations for several hours on 17 January 2013. During the wave activity period, a duskside relativistic electron precipitation (REP) event was observed by one of the ...

Combining Van Allen Probes and CubeSat Observations to Estimate Storm‐Time Maximum Outer Radiation Belt Electron Fluxes

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Understanding and forecasting extreme radiation belt electron fluxes has been a major goal in space weather since their discovery in 1958. In this study, by combining electron flux data from multiple satellite missions in different orbits, including Van Allen Probes, Electron Losses and Fields Investigation, and Colorado Inner Radiation Belt ...

Energetic, relativistic and ultra-relativistic electrons: Comparison of long-term VERB code simulations with Van Allen Probes measurements [PDF]

, 2015
In this study, we compare long-term simulations performed by the Versatile Electron Radiation Belt (VERB) code with observations from the Magnetic Electron Ion Spectrometer and Relativistic Electron-Proton Telescope instruments on the Van Allen Probes ...

The Global Propagation of Hiss Waves Originating From Dynamic Plasmaspheric Plume

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Hiss waves play a critical role in shaping Earth's radiation belts and mediating magnetosphere‐ionosphere energy transfer. Intense hiss emissions are frequently generated within dynamic plasmaspheric plumes through linear and nonlinear wave‐particle interactions.

A Personal Voyage Among Earth and Space Physics Disciplines

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract I have organized my thoughts in an autobiographical way in relation to the several distinct phases of my career encompassing Earth and space physics. I discuss atmospheric and space physics topics of interest to me in an international context, and I emphasize the value of community activities and international conferences for the interchange ...
