  • Estimation of cold plasma outflow during geomagnetic storms 
    Haaland, Stein; Eriksson, A.; Maes, L.; Baddeley, Lisa; Barakat, A.; Chappell, R.; Eccles, V.; Johnsen, C.; Lybekk, Bjørn; Li, K.; Pedersen, A; Schunk, R.; Welling, D. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Low-energy ions of ionospheric origin constitute a significant contributor to the magnetospheric plasma population. Measuring cold ions is difficult though. Observations have to be done at sufficiently high altitudes and ...
  • North-south asymmetries in cold plasma density in the magnetotail lobes: Cluster observations 
    Haaland, Stein; Lybekk, Bjørn; Maes, Lukas; Laundal, Karl Magnus; Pedersen, Amund; Tenfjord, Paul; Ohma, Anders; Østgaard, Nikolai; Reistad, Jone Peter; Snekvik, Kristian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    In this paper, we present observations of cold (0–70 eV) plasma density in the magnetotail lobes. The observations and results are based on 16 years of Cluster observation of spacecraft potential measurements converted ...
  • Space and atmospheric physics on Svalbard: a case for continued incoherent scatter radar measurements under the cusp and in the polar cap boundary region 
    Baddeley, Lisa; Lorentzen, Dag; Haaland, Stein; Heino, Erkka; Mann, Ingrid; Miloch, Wojciech; Oksavik, Kjellmar; Partamies, Noora; Spicher, Andres; Vierinen, Juha (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Incoherent scatter radars (ISRs) represent the only instrument (both ground and space based) capable of making high temporal and spatial resolution measurements of multiple atmospheric parameters—such as densities, ...
