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

AtmosphereOn 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.

Changes in the terrestrial atmosphere-ionosphere-magnetosphere system due to ion propulsion for solar power satellite placement [PDF]
Preliminary estimates of the effects massive Ar(+) injections on the ionosphere-plasmasphere system with specific emphasis on potential communications disruptions are given. The effects stem from direct Ar(+) precipitation into the atmosphere and from Ar(

A new model for plasmapause locations derived from IMAGE RPI and Van Allen Probes data
Journal of Space Weather and Space ClimateThe outer boundary of the plasmasphere, the plasmapause, is characterized by a sharp electron density gradient that changes under varying space weather conditions.

A DE-1/whistler study of the thermal plasma structure and dynamics in the dusk bulge sector of the magnetosphere [PDF]
The objective of this research was to obtain new understanding of the thermal plasma structure and dynamics of the plasmasphere bulge region of the magnetosphere, with special emphasis on the erosion process that results in a reduction in plasmasphere ...

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 ...
