    • 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 ...

    • Observations of Asymmetric Lobe Convection for Weak and Strong Tail Activity 

      Ohma, Anders; Østgaard, Nikolai; Reistad, Jone Peter; Tenfjord, Paul; Laundal, Karl Magnus; Moretto, Therese; Haaland, Stein; Krcelic, Patrik; Milan, Stephen Eric (Journal article; Peer reviewed, 2019)
      In this study we use high‐quality convection data from the Electron Drift Instrument on board Cluster to investigate how near‐Earth tail activity affects the average convection pattern in the magnetotail lobes when the ...

    • Suprathermal Fe in the Earth's Plasma Environment: Cluster RAPID Observations 

      Haaland, Stein; Daly, Patrick W.; Vilenius, Esa; Krcelic, Patrik; Dandouras, Iannis (Journal article; Peer reviewed, 2020)
      Baryonic matter in geospace is almost exclusively in a plasma state, with protons (H +) and to some extent ionized helium (He) and oxygen (O) being the dominant ion species. But also other heavier ion species and even ...
