Mode trapping in the plasmasphere [PDF]

Journal of Geophysical Research: Space Physics, 2008
As a result of its steplike density profile, combined with the monotonically increasing dipole magnetic field close to the Earth, compressional waves propagating outside the plasmapause can tunnel through and be trapped in a narrow layer that acts as a potential well.

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.

The Plasmasphere

, 2021
This chapter is a review of plasmaspheric research accomplishments published from September 2013 to September 2018. Much has been achieved during these five years, most of which we hope to have cited in the references section.

The Potential for a Networked Ionospheric Sounding Constellation

Space Weather, 2022
A novel networked sounding constellation mission concept is proposed. Radio sounding is the original sensing method that proved the existence of the ionosphere. Satellite‐borne sounders provided the first global observations of the terrestrial ionosphere

Prediction of plasmaspheric hiss spectral classes

Frontiers in Astronomy and Space Sciences, 2022
We present a random forests machine learning model for prediction of plasmaspheric hiss spectral classes from the Van Allen Probes dataset. The random forests model provides accurate prediction of plasmaspheric hiss spectral classes obtained by the self ...

Spatial gradients in the plasmasphere from Cluster [PDF]

, 2016
The Cluster mission allows the study of the plasmasphere with four-point measurements, including its overall density distribution, plasmaspheric plumes close to the plasmapause, and density irregularities inside the plasmasphere.

Estimated plasmasphere electron content and O⁺/H⁺ transition height during the February 2022 geomagnetic storm from Irkutsk IS radar data

Solar-Terrestrial Physics
We study the topside ionosphere above the NmF2 ionization maximum and the transition region between the ionosphere and the plasmasphere. We analyze the interaction between the topside ionosphere and the plasmasphere during a strong geomagnetic storm in ...

SAMI3 Simulations of a Persistent Plasmasphere Plume

Geophysical Research Letters, 2018
The Naval Research Laboratory Sami3 is Also a Model of the Ionosphere (SAMI3) ionosphere/plasmasphere code is used to examine the physics of a long‐lived plasmasphere plume. The May 1994 storm is simulated.

The Micro‐Broadband Receiver (μBBR) on the Very‐Low‐Frequency Propagation Mapper CubeSat

Earth and Space Science, 2021
The very low frequency (VLF) propagation mapper (VPM) is a 6U CubeSat designed to measure VLF radio waves in Low‐Earth Orbit. The science goals of the VPM mission are to measure VLF signals broadcast by the DSX mission, and to study natural and ...

Van Allen Probes Observations of Oxygen Ions at the Geospace Plume

Frontiers in Astronomy and Space Sciences, 2021
The geospace plume couples the ionosphere, plasmasphere, and magnetosphere from sub-auroral regions to the magnetopause, on polar field lines, and into the magnetotail.
