New formulation for the topside ionosphere and plasmasphere based on NeQuick

Journal of Space Weather and Space Climate
The total electron content (TEC) affecting signal propagation of Global Navigation Satellite Systems (GNSS) is strongly influenced by the topside ionosphere and plasmasphere. This study introduces a new approach to representing the two regions.

Estimated plasmasphere electron content and O⁺/H⁺ transition height during the February 2022 geomagnetic storm from Irkutsk IS radar data

Solar-Terrestrial Physics
We study the topside ionosphere above the NmF2 ionization maximum and the transition region between the ionosphere and the plasmasphere. We analyze the interaction between the topside ionosphere and the plasmasphere during a strong geomagnetic storm in ...

SAMI3 Simulations of a Persistent Plasmasphere Plume

Geophysical Research Letters, 2018
The Naval Research Laboratory Sami3 is Also a Model of the Ionosphere (SAMI3) ionosphere/plasmasphere code is used to examine the physics of a long‐lived plasmasphere plume. The May 1994 storm is simulated.

The Micro‐Broadband Receiver (μBBR) on the Very‐Low‐Frequency Propagation Mapper CubeSat

Earth and Space Science, 2021
The very low frequency (VLF) propagation mapper (VPM) is a 6U CubeSat designed to measure VLF radio waves in Low‐Earth Orbit. The science goals of the VPM mission are to measure VLF signals broadcast by the DSX mission, and to study natural and ...

Van Allen Probes Observations of Oxygen Ions at the Geospace Plume

Frontiers in Astronomy and Space Sciences, 2021
The geospace plume couples the ionosphere, plasmasphere, and magnetosphere from sub-auroral regions to the magnetopause, on polar field lines, and into the magnetotail.

Observations of the Electrodynamical Ties Between Sporadic E and the Plasmasphere

Earth and Space Science, 2020
A joint investigation was conducted of coherent backscatter radar observations of irregularities within the E and F regions and tomographic mapping of corotating plasmaspheric irregularities (CPIs) near Japan and the American northwest from June 2018 ...

The trapping of equatorial magnetosonic waves in the Earth’s outer plasmasphere [PDF]

, 2014
We investigate the excitation and propagation of equatorial magnetosonic waves observed by the Van Allen Probes and describe evidence for a trapping mechanism for magnetosonic waves in the Earth\u27s plasmasphere.

Investigation of the single layer model of GPS ionospheric data processing using IRI-90 and the attached diffusive equilibrium model of plasmaspheric electron density

Annals of Geophysics, 1997
The single layer model of GPS ionospheric data processing is compared with the International Reference Ionosphere í 1990 and the attached Diffusive Equilibrium model of Plasmasphere (IRI-90+DEP) which proved to be a good supplement to GPS data processing.

Large‐Scale Magnetosheath Jets Formed by Shock‐Discontinuity Interactions: A Three‐Dimensional Global Hybrid Simulation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Magnetosheath high‐speed jets with enhanced dynamic pressure are common in Earth's magnetosheath and can impinge on the magnetopause, driving pronounced boundary deformation. Recent observations indicate that shock–discontinuity interactions (SDIs) can generate magnetosheath jets, but the formation mechanism is still unclear.
