An extended TRANSCAR model including ionospheric convection: simulation of EISCAT observations using inputs from AMIE [PDF]
Annales Geophysicae, 2005 The TRANSCAR ionospheric model was extended to account for the convection of the magnetic field lines in the auroral and polar ionosphere. A mixed Eulerian-Lagrangian 13-moment approach was used to describe the dynamics of an ionospheric plasma tube ...

Positive storm effects in the dayside polar ionospheric F-region observed by EISCAT and ESR during the magnetic storm of 15 May 1997 [PDF]
Annales Geophysicae, 2002 EISCAT/ESR radar data and in situ FAST and POLAR satellite observations are coordinately analyzed to investigate positive ionospheric storm effects in the dayside upper F-region in both the polar cap and the auroral oval during the magnetic storm ...

A space hurricane over the Earth's polar ionosphere. [PDF]
Nat Commun, 2021 AbstractIn Earth’s low atmosphere, hurricanes are destructive due to their great size, strong spiral winds with shears, and intense rain/precipitation. However, disturbances resembling hurricanes have not been detected in Earth’s upper atmosphere. Here, we report a long-lasting space hurricane in the polar ionosphere and magnetosphere during low solar ...

Local Mapping of Polar Ionospheric Electrodynamics
Journal of Geophysical Research: Space Physics, 2022 Abstract An accurate description of the state of the ionosphere is crucial for understanding the physics of Earth's coupling to space, including many potentially hazardous space weather phenomena. To support this effort, ground networks of magnetometer stations, optical instruments, and radars have been deployed.

Space- and ground-based investigations of solar wind-magnetosphere-ionosphere coupling [PDF]
, 2006 This paper provides a brief review of the understanding of the coupled solar wind–magnetosphere–ionosphere system that can be attained from observations of the size of the ionospheric polar caps from space and the ground.
