Analysis of South Atlantic Anomaly Influence on Low‐Earth Orbit Lightning Observations

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract The low‐Earth orbit Optical Transient Detector (OTD) and Lightning Imaging Sensor (LIS) instruments, spanning 1995–2023, have spatiotemporal patterns within their metadata that are consistent with the South Atlantic Anomaly (SAA). While the SAA had a known influence on these instruments, this study details new variability and impacts.

Community Voices on the Future of Radiation Belt Research: A Summary of the 2024 GEM Radiation Belt Focus Group Round‐Table Discussion

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Earth's radiation belts are the regions where highly energetic charged particles are trapped by Earth's magnetic field, posing significant risks to the satellites and other space‐based technologies. Understanding the dynamics of the radiation belts is critical not only for advancing fundamental plasma physics but also for predicting and ...

Electron Energy Spectra in Jupiter's Radiation Belts From Juno‐JEDI

Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract Radiation transport simulations of the Jupiter Energetic‐particle Detector Instrument (JEDI) onboard the Juno spacecraft were performed to understand its response to high energy electrons. Determination of the JEDI response function is the first rigorous effort of its kind and was used to reconstruct the true electron foreground, extending the

The electron density at the midpoint of the plasmapause

Frontiers in Astronomy and Space Sciences
The high density plasmasphere in the magnetosphere is often separated from a lower density region outside of the plasmasphere, called the plasmatrough, by a sharp gradient in electron density called the plasmapause.

Statistical Properties of Molecular Ions in the Ring Current Observed by the Arase (ERG) Satellite

Geophysical Research Letters, 2019
Molecular ions in the magnetosphere can be a tracer of fast ion outflows from the deep ionosphere. Statistical properties of molecular ions (O2+/NO+/N2+) in the ring current are investigated based on ion composition measurements (

Enhanced Energetic Neutral Atom Imaging

Frontiers in Astronomy and Space Sciences, 2019
Over the past two decades, instruments designed to image plasmas in energetic neutral atom (ENA) emission have flown in space. In contrast to typical satellite-based in situ instruments, ENA imagers provide a global view of the magnetosphere because they

Random Forest Model of Ultralow‐Frequency Magnetospheric Wave Power

Earth and Space Science, 2020
Models of magnetospheric ultralow‐frequency (ULF) waves can be used to study wave phenomena and to calculate the effect of these waves on the energization and transport of radiation belt electrons.

A correlative investigation of the propagation of ULF wave power through the dayside magnetosphere [PDF]

Three different ULF wave phenomena (azimuthally polarized Pc 3 pulsations, radially polarized Pc 4 pulsations, and solitary Pc 5 pulsations related to solar wind pressure pulses) were studied. The main problems covered are: (1) how do magnetospheric Pc 3-
