A statistical comparison of hot-ion properties at geosynchronous orbit during intense and moderate geomagnetic storms at solar maximum and minimum. [PDF]
, 2006 Hot-ion measurements at geosynchronous orbit from the Los Alamos Magnetospheric Plasma Analyzer (MPA) instrument during geomagnetic storms at solar maximum (July 1999–June 2002) and at solar minimum (July 1994–June 1997) are collected, categorized, and ...

Morphology in the total electron content under geomagnetic disturbed conditions: results from global ionosphere maps [PDF]
Annales Geophysicae, 2007 Using 8-year global ionosphere maps (GIMs) of TEC products from the Jet Propulsion Laboratory (JPL), we make a statistical study on the morphology of the global ionospheric behaviors with respect to the geomagnetic disturbances.

Particle precipitation during ICME-driven and CIR-driven geomagnetic storms [PDF]
, 2008 Interplanetary coronal mass ejections (ICME) and corotating interaction regions (CIR) alter the parameters of the solar wind and interplanetary magnetic field (IMF) that affect conditions in the Earth's magnetosphere and particle precipitation in the ...

Statistical study and corresponding evolution of plasmaspheric plumes under different levels of geomagnetic storms [PDF]
Annales Geophysicae, 2022 Using observations of Van Allen Probes, we present a statistical study of plasmaspheric plumes in the inner magnetosphere. Plasmaspheric plumes tend to occur during the recovery phase of geomagnetic storms.

April 2000 geomagnetic storm: Ionospheric drivers of large geomagnetically induced currents [PDF]
, 2003 International audienceGeomagnetically induced currents (GIC) flowing in technological systems on the ground are a direct manifestation of space weather. Due to the proximity of very dynamic ionospheric current systems, GIC are of special interest at high

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

A study of geomagnetic storms [PDF]
Geophysical Journal International, 1978 The interplanetary energy flux is estimated on the basis of the Poynting flux and its variations with the rate of energy dissipation in terms of: (1) the ring-current particle injection, (2) Joule dissipation in the ionosphere, and (3) auroral particle injection for 15 major geomagnetic storms.

A Qualitative Study of the Ionospheric Weak Response to Super Geomagnetic Storms
Atmosphere, 2020 The ionospheric response to a geomagnetic storm is a geophysical process. Although strong geomagnetic storms input more energy into the Earth’s upper atmosphere, the ionospheric response often does not reflect the same level of variation as the ...

Width of plasmaspheric plumes related to the level of geomagnetic storm intensity [PDF]
Annales Geophysicae, 2022 The plume is a plasma region in the magnetosphere that is detached from the main plasmasphere. It significantly contributes to the dynamic processes in both the inner and outer magnetosphere.
