Geophysical Research Letters, 2016 Using the Van Allen Probe in situ measured magnetic field and electron data, we examine the solar wind dynamic pressure and interplanetary magnetic field (IMF) effects on global magnetic field and outer radiation belt relativistic electrons (≥1.8 MeV ...

Large-scale properties of the interplanetary magnetic field [PDF]
Early theoretical work of Parker is presented along with the observational evidence supporting his Archimedes spiral model. Variations present in the interplanetary magnetic field from the spiral angle are related to structures in the solar wind.

Dependence of the High Latitude Middle Atmosphere Ionization on Structures in Interplanetary Space [PDF]
, 1984 The precipitation of high energetic electrons during and after strong geomagnetic storms into heights below 100 km in middle and subauroral latitudes is markedly modulated by the structure of the interplanetary magnetic field (IMF).

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 ...

Global MHD Simulations: Magnetosphere–Ionosphere Coupling Dependence on Conductance Model
Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Eighty‐five geomagnetic storms were simulated with the space weather modeling framework Geospace model using two different ionospheric conductance models. One set used the legacy conductances within the Ridley ionosphere model, while the other set used the newly developed conductance model for extreme events conductance model.

Termination Shock Asymmetries as Seen by the Voyager Spacecraft: The Role of the Interstellar Magnetic Field and Neutral Hydrogen [PDF]
, 2007 We show that asymmetries of the termination shock due to the influence of the interstellar magnetic field (ISMF) are considerably smaller in the presence of neutral hydrogen atoms, which tend to symmetrize the heliopause, the termination shock, and the ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract The Geospace Dynamics Constellation (GDC) mission aims to investigate the dynamic coupling between the magnetosphere, ionosphere, and thermosphere by resolving key spatiotemporal processes at scales ranging from local to global. A key aspect is GDC's ability to reconstruct hemispheric‐scale high‐latitude electrodynamics with comprehensive ...

A case study of large-amplitude ULF waves in the Martian foreshock
Earth and Planetary Physics, 2020 Foreshock ultralow frequency (ULF) waves constitute a significant physical phenomenon in the plasma environment of terrestrial planets. The occurrence of these waves, associated with backstreaming particles reflected and accelerated at the bow shock ...
