Solar wind-magnetosphere-ionosphere interactions in the earth's plasma environment [PDF]

, 2003
The properties of the Earth’s coupled magnetosphere-ionosphere system are dominated by its interaction with the solar wind plasma, mediated by magnetic reconnection processes at the magnetopause interface.

First simultaneous observations of flux transfer events at the high-latitude magnetopause by the cluster spacecraft and pulsed radar signatures in the conjugate ionosphere by the CUTLASS and EISCAT radars [PDF]

, 2001
Cluster magnetic field data are studied during an outbound pass through the post-noon high-latitude magnetopause region on 14 February 2001. The onset of several minute perturbations in the magnetospheric field was observed in conjunction with a ...

Dependence of the open-closed field line boundary in Saturn's ionosphere on both the IMF and solar wind dynamic pressure : comparison with the UV auroral oval observed by the HST [PDF]

, 2008
We model the open magnetic field region in Saturn's southern polar ionosphere during two compression regions observed by the Cassini spacecraft upstream of Saturn in January 2004, and compare these with the auroral ovals observed simultaneously in ...

Structure and dynamics of the ionosphere [PDF]

Nature, 1982
The structure of the Venus ionosphere and the major processes occurring within it are summarized. The daytime ionosphere is created by solar EUV radiation incident on the thermosphere; it is in photochemical equilibrium near its peak at about 142 km, where O2(+) is the major ion, and near diffusive equilibrium in its upper regions, where the major ion ...

On the possibility of ion-drag to induce dynamic instability in the lower thermosphere neutral gas [PDF]

Annales Geophysicae, 2000
Strong wind shears may result in dynamic instability, often characterised by the Richardson number lying between zero and 0.25. The extent to which electric-field driven ion flow may induce such neutral wind shears is examined. Further, it is proposed

Westward moving dynamic substorm features observed with the IMAGE magnetometer network and other ground-based instruments [PDF]

Annales Geophysicae, 1998
We present the ground signatures of dynamic substorm features with particular emphasis on the event interpretation capabilities provided by the IMAGE magnetometer network.

Tianwen-1 and MAVEN Observations of the Response of Mars to an Interplanetary Coronal Mass Ejection

The Astrophysical Journal, 2023
Interplanetary coronal mass ejections (ICMEs) are solar transients that have significant effects on the upper atmosphere and ionosphere of Mars. The simultaneous spacecraft observations from Tianwen-1/MOMAG in solar wind and multiple instruments on board

Phenomena in the ionosphere-magnetosphere system induced by injection of powerful HF radio waves into nightside auroral ionosphere [PDF]

, 2005
International audienceExperimental results from three ionospheric HF pumping experiments in overdense E or F regions are summarized. The experiments were conducted by the use of the EISCAT HF Heating facility located near Tromsø, Norway, allowing HF ...
