• Characteristics of the flank magnetopause: Cluster observations 

      Haaland, Stein; Reistad, Jone Peter; Tenfjord, Paul; Gjerloev, Jesper W.; Maes, Lukas; deKeyser, Johan; Maggiolo, Romain; Anekallu, Chrandrasehkar; Dorville, Nicolas (Peer reviewed; Journal article, 2014-11)
      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 the low-latitude dawn and dusk flanks of ...
    • Estimating the fate of oxygen ion outflow from the high-altitude cusp 

      Krcelic, Patrik; Haaland, Stein; Maes, Lukas; Slapak, Rikard; Schillings, Audrey (Journal article; Peer reviewed, 2020)
      We have investigated the oxygen escape-to-capture ratio from the high-altitude cusp regions for various geomagnetic activity levels by combining EDI and CODIF measurements from the Cluster spacecraft. Using a magnetic field ...
    • 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 (Peer reviewed; Journal article, 2017-01)
      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 ...
    • Solar illumination control of ionospheric outflow above polar cap arcs 

      Maes, Lukas; Maggiolo, Romain; De Keyser, Johan; Dandouras, Iannis; Fear, Robert C.; Fontaine, Dominique; Haaland, Stein (Peer reviewed; Journal article, 2015-03-12)
      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 associated with polar cap arcs, using Cluster. ...
