A density-temperature description of the outer electron radiation belt during geomagnetic storms [PDF]

, 2009
Bi-Maxwellian fits are made to energetic-electron flux measurements from seven satellites in geosynchronous orbit, yielding a number density (n) and temperature (T) description of the outer electron radiation belt.

The effect of disturbed-time electric fields on the inner plasmasphere

Annales Geophysicae
Results from a mathematical model provide a description of the mid-latitude, low <i>L</i>-shell ionosphere and plasmasphere. Variations in the composition and dynamics of the plasmasphere and changes in the nature of the coupling between the ...

Effects of the Geomagnetic Superstorms of 10–11 May 2024 and 7–11 October 2024 on the Ionosphere and Plasmasphere

Atmosphere
On 10 May 2024 at 17 h:07 UTC, the simultaneous arrival of several solar coronal mass ejections (CMEs) generated the strongest geomagnetic storm of the last twenty years, with a minimum Dst = −412 nT, usually referred to as the Mother’s Day event.

A new model for plasmapause locations derived from IMAGE RPI and Van Allen Probes data

Journal of Space Weather and Space Climate
The outer boundary of the plasmasphere, the plasmapause, is characterized by a sharp electron density gradient that changes under varying space weather conditions.

Dynamics of midlatitude light ion trough and plasmatails [PDF]

Light ion trough measurements near midnight made by the RF ion mass spectrometer on OGO-4 operating in the high resolution mode in Feb. 1968 reveal the existence of irregular structure on the low latitude side of the midlatitude trough.

Earth's plasmasphere awaits rediscovery

Eos, Transactions American Geophysical Union, 1995
The plasmasphere is a high‐density, toruslike inner magnetospheric region whose configuration and dynamics are highly sensitive to disturbance activity in the solar‐terrestrial environment. Although many space scientists consider the plasmasphere to be a phenomenon of modest geophysical importance, one that has long been relatively well measured and ...

Magnetosphere of Saturn [PDF]

Models of the Saturnian magnetosphere based on the application of magnetospheric scaling relations to a spin-aligned planetary magnetic dipole, that produces a surface equatorial field strength in the range 0.5 to 2 gauss, exhibit the following ...
