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.

Global Circulation of Martian Ionospheric Currents Revealed by Magnetometer Data
AGU Advances, Volume 7, Issue 6, September 2026.Abstract In the dynamo region of the Martian ionosphere, a large‐scale current is generated by charge separation: ions collide with neutrals while electrons preferentially gyrate around local magnetic field lines. Using MAVEN magnetometer data and a physics‐informed neural network constrained by Ampère's law and Gauss's law for magnetism (the Neural ...

Extreme Radiation Belt Dropout During the May 2024 Superstorm
AGU Advances, Volume 7, Issue 6, September 2026.Abstract The geomagnetic superstorm in May 2024 represents the most extreme space weather event over the past two decades, offering a unique opportunity to investigate radiation belt electron dynamics under exceptionally strong solar wind driving conditions. Observations from the Arase satellite show that relativistic electron fluxes dropped by several

Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract Numerical modeling has been a key component in the study of the Mars space environment, providing a comprehensive global representation that is not always easy to obtain in spacecraft measurements. However, there are inconsistencies in data‐model and model‐model comparisons, regardless of whether the simulation conditions are identical or ...

Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract In situ observations of thermospheric composition have long been scarce, limiting our understanding of the upper atmosphere and its response to space weather. This study focuses on the Neutral Gas Mass Spectrometer (NGMS) onboard the TM19 and TM20 satellites of China's TianMu‐1 constellation, presenting the first systematic elaboration of its ...

The high-energy tail of energetic electron precipitation: case studies
Frontiers in Astronomy and Space SciencesPrecipitating plasma sheet, ring current, and radiation belt electrons will affect the ionization level and composition of the neutral atmosphere. Knowledge gaps remain regarding the frequency, intensity, and energy spectrum of the Medium Energy Electron

Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract Geomagnetic observatory networks provide continuous data for space weather monitoring, field modeling, and solid Earth geophysics. Rapid urbanization, however, has introduced pervasive electromagnetic interference from subway traction systems, degrading data quality at a growing number of urban stations.

Looking Into Pulsar Magnetospheres [PDF]
Astrophysics and Space Science, 2001 AbstractDiffractive and refractive magnetospheric scintillations may allow direct probing of the plasma inside the pulsar light cylinder. The unusual electrodynamics of the strongly magnetized electron-positron plasma allows separation of the magnetospheric and interstellar scattering.
