An auroral westward flow channel (AWFC) and its relationship to field-aligned current, ring current, and plasmapause location determined using multiple spacecraft observations [PDF]
An auroral westward flow channel (AWFC) is a latitudinally narrow channel of unstable F-region plasma with intense westward drift in the dusk-to-midnight sector ionosphere. AWFCs tend to overlap the equatorward edge of the auroral oval, and their life

Magnetospheric processes in the plasmapause
The current experimental and theoretical status on the existence and importance of the plasmapause as a magnetospheric boundary was the subject of a conference on Fundamental Magnetospheric Processes in the Plasmapause Region, held at Huntsville, Ala., October 25–27, 1983, under the joint sponsorship of the Marshall Space Flight Center and the ...

Modulation of NTC frequencies by Pc5 ULF pulsations : experimental test of the generation mechanism and magnetoseismology of the emitting surface [PDF]
Nonthermal continuum (NTC) radiation is believed to be emitted by the conversion of an electrostatic wave into an electromagnetic one, which takes place at the Earth's magnetic equator.

A machine-learning-based electron density (MLED) model in the inner magnetosphere
Plasma density is an important factor in determining wave-particle interactions in the magnetosphere. We develop a machine-learning-based electron density (MLED) model in the inner magnetosphere using electron density data from Van Allen Probes between ...

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

Polar observations of electron density distribution in the Earth’s magnetosphere. 2. Density profiles [PDF]
Using spacecraft potential measurements of the Polar electric field experiment, we investigate electron density variations of key plasma regions within the magnetosphere, including the polar cap, cusp, trough, plasmapause, and auroral zone.

The Evolution of Whistler Hiss‐Like Waves Across Plasmapause: Hiss to Exohiss
The exohiss waves are hiss‐like whistler mode waves that occur outside plasmapause. Although these waves can cause the loss of radiation belt electrons ∼

Ionospheric Pc1 waves during a storm recovery phase observed by the China Seismo-Electromagnetic Satellite [PDF]
During the storm recovery phase on 27 August 2018, the China Seismo-Electromagnetic Satellite (CSES) detected Pc1 wave activities in both the Northern Hemisphere and Southern Hemisphere in the high-latitude, post-midnight ionosphere with a central ...
