Giant Undulations Driven by Pitch‐Angle Scattering of Time Domain Structures Modulated by Plasmapause Surface Wave [PDF]
Geophysical Research LettersPlasmapause surface waves (PSWs) near the plasmapause boundary are regarded to be the magnetospheric source of ionospheric auroral giant undulations (GUs) located at the equatorward boundary of diffuse aurora.

Journal of Geophysical Research: Space Physics, 2020 AbstractRecent studies based on CLUSTER, CRRES, and especially on THEMIS satellite data have revealed the statistical behavior of the global plasmapause such as eastward azimuthal plasmapause propagation and radial plasmapause motion between 21 and 07 magnetic local times (MLTs) most likely at postmidnight.

The distribution of plasmaspheric hiss wave power with respect to plasmapause location
Geophysical Research Letters, 2016 In this work, Van Allen Probes data are used to derive terrestrial plasmaspheric hiss wave power distributions organized by (1) distance away from the plasmapause and (2) plasmapause distance from Earth.

Ionospheric and magnetospheric “plasmapauses” [PDF]
Planetary and Space Science, 1978 Abstract During August 1972, Explorer 45 orbiting near the equatorial plane with an apogee of ∼5.2 R e traversed magnetic field lines in close proximity to those simultaneously traversed by the topside ionospheric satellite ISIS 2 near dusk in the L range 2.0–5.4.

Cross‐ L* Coherence of the Outer Radiation Belt During Storms and the Role of the Plasmapause [PDF]
Journal of Geophysical Research: Space Physics, 2021 The high energy electron population in Earth's outer radiation belt is extremely variable, changing by multiple orders of magnitude on timescales that vary from under an hour to several weeks.

The Roles of the Magnetopause and Plasmapause in Storm‐Time ULF Wave Power Enhancements [PDF]
Journal of Geophysical Research: Space Physics, 2021 Ultra low frequency (ULF) waves play a crucial role in transporting and coupling energy within the magnetosphere. During geomagnetic storms, dayside magnetospheric ULF wave power is highly variable with strong enhancements that are dominated by elevated ...

Relation of the Plasmapause to the Midlatitude Ionospheric Trough, the Sub‐Auroral Temperature Enhancement and the Distribution of Small‐Scale Field Aligned Currents as Observed in the Magnetosphere by THEMIS, RBSP, and Arase, and in the Topside Ionosphere by Swarm [PDF]
Journal of Geophysical Research: Space Physics, 2022 The relation between the plasmapause (PP) and various ionospheric phenomena, such as the midlatitude ionospheric trough (MIT) has been studied for decades.

Multi-satellite study of the excitation of Pc3 and Pc4-5 ULF waves and their penetration across the plasmapause during the 2003 Halloween superstorm [PDF]
Annales Geophysicae, 2015 We use multi-satellite and ground-based magnetic data to investigate the concurrent characteristics of Pc3 (22–100 mHz) and Pc4-5 (1–22 mHz) ultra-low-frequency (ULF) waves on the 31 October 2003 during the Halloween magnetic superstorm. ULF waves are
