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.

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

The plasmapause revisited

, 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 ...

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 ...

Tour of the Plasmasphere and Plasmapause

, 2004
The plasmasphere is a region of ionospheric plasma which co-rotates with the Earth, carried by the magnetic field lines. This plasma tends to be colder (i.e. the ions have lower average energy) than the outer region of the magnetosphere.

Spatial Evolution Characteristics of Plasmapause Surface Wave During a Geomagnetic Storm on 16 July 2017

Geophysical Research Letters
Boundary dynamics are crucial for the transport of energy, mass, and momentum in geospace. The recently discovered plasmapause surface wave (PSW) plays a key role in the inner magnetosphere dynamics.

Inner Magnetospheric Oxygen Torus Induced by Electromagnetic Ion Cyclotron Waves

Geophysical Research Letters
Cold oxygen ions escaping from the ionosphere and temporarily trapped near the plasmapause form the oxygen torus. Mass‐loading by these oxygen ions significantly affects magnetospheric plasma processes.
