Østgaard, Nikolai; Ostgaard, N; Snekvik, Kristian; Borg, Anette Lauen; Åsnes, Arne; Asnes, A; Pedersen, Arne; Øieroset, Marit; Oieroset, M; Phan, Tai D.; Phan, T; Haaland, Stein (2009)
Estimating the capture and loss of cold plasma from ionospheric outflow

Haaland, Stein; Eriksson, Anders; Engwall, Erik; Lybekk, Bjørn; Nilsson, Hans; Pedersen, Arne; Svenes, Knut Ragnar; André, Mats; Förster, Matthias; Li, K.; Johnsen, Christine; Østgaard, Nikolai (2012)

An important source of magnetospheric plasma is cold plasma from the terrestrial ionosphere. Low energy ions travel along the magnetic field lines and enter the magnetospheric lobes where they are convected toward the tail ...
A survey of the polar cap density based on Cluster EFW probe measurements: Solar wind and solar irradiation dependence

Haaland, Stein; Svenes, Knut Ragnar; Lybekk, Bjørn; Pedersen, Arne (2012)

The plasma density above the Earth's polar caps provide crucial information about the state of the magnetosphere. This region of space is known for its tenuous plasma and extremely low plasma densities, thus making traditional ...
