A Comparison of the Location of the Mid‐Latitude Trough and Plasmapause Boundary

, 2021
: We have compared the location of the mid‐latitude trough observed in two dimensional vertical total electron content (vTEC) maps with four plasmapause boundary models, Radiation Belt Storm Probes (RBSP) observations, and IMAGE extreme ultraviolet (EUV)

Identifying the Magnetospheric Drivers of Giant Undulations: Global Modeling of the Evolving Inner Magnetosphere and Its Auroral Manifestations

Geophysical Research Letters
We present the first global geospace simulation to reproduce auroral giant undulations (GUs). To identify their magnetospheric drivers, we employ the MAGE (Multiscale Atmosphere‐Geospace Environment) model in a case study of a geomagnetic storm for which

Characteristics of precipitating energetic electron fluxes relative to the plasmapause during geomagnetic storms [PDF]

, 2014
In this study we investigate the link between precipitating electrons from the Van Allen radiation belts and the dynamical plasmapause. We consider electron precipitation observations from the Polar Orbiting Environmental Satellite (POES) constellation ...

The plasmapause revisited [PDF]

, 1976
Saturation of the dc double probe instrument on Explorer 45 was used to identify the plasmapause. A data base was developed to statistically study the average position of the plasmapause over 14.5 hours of magnetic local time under differing magnetic ...

Giant Undulations Driven by Pitch‐Angle Scattering of Time Domain Structures Modulated by Plasmapause Surface Wave

Geophysical Research Letters
Plasmapause 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.

Theory and Modeling of Large Scale Plasmapause Surface Waves [PDF]

The plasmapause in Earth's magnetosphere represents the boundary between the plasma which co-rotates with the Earth (plasmasphere), and the more tenuous plasmatrough outside.

ULF Wave Characteristics in the Auroral Zone through the Plasmapause

Antarctic Record, 1979
Geomagnetic pulsations in the auroral zone through the plasma-pause were examined on the basis of IMS observation data obtained in Canada. It was shown that the geomagnetic pulsations in the daytime are reasonably accounted for in terms of HM waves ...

Plasmapause undulation of 17 April 2002

Geophysical Research Letters, 2004
We report IMAGE EUV observations of a striking undulatory motion of the plasmapause that occurred on 17 April 2002, in which a large ripple propagated westward across the duskside plasmapause. From the plasmapause motion we infer a peak E‐field of ≈3 mV/m associated with the undulation, and estimate the undulation's equatorial azimuthal speed to be 0.9
