A coordinated ground-based and IMAGE satellite study of quiet-time plasmaspheric density profiles [PDF]

open access: yes, 2003
Cold plasma mass density profiles in the plasmasphere have been determined for the geomagnetically quiet day of 19th August 2000 using the cross-phase technique applied to ground-based magnetometer data from the SAMNET, IMAGE and BGS magnetometer arrays.

Electron loss rates from the outer radiation belt caused by the filling of the outer plasmasphere: The calm before the storm [PDF]

open access: yes, 2009
Measurements from seven spacecraft in geosynchronous orbit are analyzed to determine the decay rate of the number density of the outer electron radiation belt prior to the onset of high-speed-stream-driven geomagnetic storms.

He+ dominance in the plasmasphere during geomagnetically disturbed periods: 1. Observational results [PDF]

open access: yes, 2002
Observations made by the DMSP 1710 satellite during the recovery phase from geomagnetic disturbances in June 1991 show regions of He+ dominance around 830 km altitude at 09:00 MLT.

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

open access: yes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

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

open access: yesGeophysical 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.

Does Ring Current Heating Generate the Observed O+ Shell?

open access: yesGeophysical Research Letters, 2020
The Naval Research Laboratory (NRL) Sami3 is Also a Model of the Ionosphere (SAMI3) ionosphere/plasmasphere code is used to examine the effect of ring current heating during a storm. With a ring current heating function added to SAMI3, a cold thermal (

The Potential for a Networked Ionospheric Sounding Constellation

open access: yesSpace 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

open access: yesFrontiers 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 ...
