Combined model of topside ionosphere and plasmasphere derived from radio-occultation and Van Allen Probes data [PDF]

Scientific Reports, 2022
In the last years, electron density profile functions characterized by a linear dependence on the scale height showed good results when approximating the topside ionosphere. The performance above 800 km, however, is not yet well investigated.

Density structures inside the plasmasphere: Cluster observations [PDF]

Annales Geophysicae, 2004
The electron density profiles derived from the EFW and WHISPER instruments on board the four Cluster spacecraft reveal density structures inside the plasmasphere and at its outer boundary, the plasmapause.

Recirculation of plasmasphere material during idealized magnetic storms

Frontiers in Physics, 2023
The fate of flux tube material once it is eroded from of the plasmasphere through a dayside plume remains unknown. The eroded plasmasphere material can be either swept away by the solar wind and lost from Earth’s system, or recirculated into the inner ...

Van Allen Probes observation of plasmaspheric hiss modulated by injected energetic electrons [PDF]

Annales Geophysicae, 2018
Plasmaspheric hiss was observed by Van Allen Probe B in association with energetic electron injections in the outer plasmasphere. The energy of injected electrons coincides with the minimum resonant energy calculated for the observed hiss wave ...

The plasmasphere of Neptune [PDF]

Journal of Geophysical Research: Planets, 1998
We examine the plausible existence of Neptune's plasmasphere and study the drift of particles inside it. Using the O8 magnetic field model [Connerney et al., 1991] and assuming a uniform solar wind convection electric field, the plasma convection time and refilling time are calculated in a Euler potential coordinate system [Ho el al., 1997]. The plasma

Links of the Plasmapause With Other Boundary Layers of the Magnetosphere: Ionospheric Convection, Radiation Belt Boundaries, Auroral Oval

Frontiers in Astronomy and Space Sciences, 2021
The plasmapause marks the limit of the plasmasphere and is characterized by a sudden change in plasma density. This can influence the other regions of the magnetosphere, including due to different waves circulating inside and outside the plasmasphere. In

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.

The interactions between ULF waves and cold charged particles in the Earth's magnetosphere

地球与行星物理论评, 2022
In the solar wind-magnetosphere coupling processes, many kinds of plasma waves can be excited in the Earth's magnetosphere including ULF waves, hiss waves, chorus waves, etc. Among these waves, ULF waves are featured by the lowest wave frequency (1 mHz～1

Whistlers in the Plasmasphere

Journal of Geophysical Research: Space Physics, 2021
AbstractWe study packages of VLF whistler‐mode waves observed by the Van Allen Probes satellites in the equatorial plasmasphere. We demonstrate that the main mechanism providing localization of these waves inside relatively broad (>1 RE across the ambient magnetic field) magnetospheric regions is a combined effect of the transverse gradients in the ...

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.
