Separation and Quantification of Ionospheric Convection Sources: 1. A New Technique
J. P. Reistad, K. M. Laundal, N. Østgaard +4
This paper describes a novel technique that allows separation and quantification of different sources of convection in the high-latitude ionosphere. To represent the ionospheric co…
Separation and Quantification of Ionospheric Convection Sources: 2. The Dipole Tilt Angle Influence on Reverse Convection Cells During Northward IMF
J. P. Reistad, K. M. Laundal, N. Østeward +5
This paper investigates the influence of Earth's dipole tilt angle on the reverse convection cells (sometimes referred to as lobe cells) in the Northern Hemisphere ionosphere durin…
Dayside and nightside magnetic field responses at 780 km altitude to dayside reconnection
K. Snekvik, N. Østgaard, P. Tenfjord +4
During southward interplanetary magnetic field, dayside reconnection will drive the Dungey cycle in the magnetosphere, which is manifested as a two-cell convection pattern in the i…
Birkeland current effects on high-latitude groundmagnetic field perturbations
K. M. Laundal, S. E. Haaland, N. Lehtinen +8
Magnetic perturbations on ground at high latitudes are directly associated only with the divergence-free component of the height-integrated horizontal ionospheric current, $\textbf…
Characteristics of the flankmagnetopause: Cluster observations
S. Haaland, J. Reistad, P. Tenfjord +6
The magnetopause is a current sheet forming the boundary between the geomagnetic field on one side and the shocked solar wind on the other side. This paper discusses properties of…
Solar illumination control of ionospheric outflow above polar cap arcs
L. Maes, R. Maggiolo, J. De Keyser +4
We measure the flux density, composition, and energy of outflowing ions above the polar cap, accelerated by quasi-static electric fields parallel to the magnetic field and associat…
