The Effect of the Thermosphere on Ionosphere Outflows

Frontiers in Astronomy and Space Sciences, 2021
The Naval Research Laboratory (NRL) Sami2 is Another Model of the Ionosphere (SAMI2) and Sami3 is Also a Model of the Ionosphere (SAMI3) ionosphere/plasmasphere codes have shown that thermosphere composition and winds significantly affect H+ outflows ...

Premidnight plasmaspheric “plumes” [PDF]

Journal of Geophysical Research: Space Physics, 1997
To explain observations of brief intervals of cold, dense plasma by geosynchronous satellites in the midnight sector prior to or during substorm onset, it has recently been proposed that dense plasmaspheric plasma is drawn out to geosynchronous orbit in the premidnight region by inductive electric fields during the growth phase of a geomagnetic ...

Magnetosonic Waves Above the Lower Hybrid Frequency in Cyclotron Resonance With the Van Allen Radiation Belt Electrons

Geophysical Research Letters, 2022
Cyclotron resonance with magnetosonic waves was usually considered unimportant for the Van Allen radiation belt electron dynamics because it occurs at energies that are too high.

Pi 2 waves simultaneously observed by Cluster and CPMN ground-based magnetometers near the plasmapause [PDF]

Annales Geophysicae, 2011
We have analyzed an event on 14 February 2003 in which Cluster satellites and the CPMN ground magnetometer chain made simultaneous observations of a Pi 2 pulsation along the same meridian.

PINE-RT: An operational real-time plasmasphere model

Frontiers in Astronomy and Space Sciences, 2023
The plasmasphere is a region of cold and dense plasma around the Earth, corotating with the Earth. Its plasma density is very dynamic under the influence of the solar wind and it influences several processes such as the GPS navigation, the surface ...

Formation of the oxygen torus in the inner magnetosphere: Van Allen Probes observations [PDF]

, 2015
We study the formation process of an oxygen torus during the 12–15 November 2012 magnetic storm, using the magnetic field and plasma wave data obtained by Van Allen Probes.

A plasmaspheric cavity resonance in a longitudinally non-uniform plasmasphere [PDF]

Earth, Planets and Space, 2014
Power spectra of a plasmaspheric cavity resonance (strictly, a plasmaspheric virtual resonance) in a longitudinally non-uniform plasmasphere are calculated. It is shown that the spectra depend on longitude. Therefore, a cavity resonance mode can have local time depending spectra when the plasmasphere is non-uniform in a longitudinal direction.

Deep learning model of hiss waves in the plasmasphere and plumes and their effects on radiation belt electrons

Frontiers in Astronomy and Space Sciences, 2023
Hiss waves play an important role in removing energetic electrons from Earth’s radiation belts by precipitating them into the upper atmosphere. Compared to plasmaspheric hiss that has been studied extensively, the evolution and effects of plume hiss are ...

Internal source of plasmaspheric hiss on Earth

地球与行星物理论评, 2022
Plasmasphere is an upward extension of the ionosphere at low and middle latitudes along the closed magnetic field lines rooted in the Earth, where the trapped whistler-mode waves in the frequency range from tens to thousands of Hertz are named as ...

Disappearance of plasmaspheric hiss following interplanetary shock [PDF]

, 2015
Plasmaspheric hiss is one of the important plasma waves controlling radiation belt dynamics. Its spatiotemporal distribution and generation mechanism are presently the object of active research.
