    • Measuring small-scale plasma irregularities in the high-latitude E- and F-regions simultaneously 

      Ivarsen, Magnus Fagernes; St‐Maurice, Jean-Pierre; Hussey, Glenn C.; Spicher, Andres; Jin, Yaqi; Lozinsky, Adam; Goodwin, Lindsay Victoria; Galeschuk, Draven; Park, Jaeheung; Clausen, Lasse (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-18)
      The ionosphere, Earth’s space environment, exhibits widespread turbulent structuring, or plasma irregularities, visualized by the auroral displays seen in Earth’s polar regions. Such plasma irregularities have been studied for decades, but plasma turbulence remains an elusive phenomenon. We combine scale-dependent measurements from a ground-based radar with satellite observations to characterize ...

    • Statistical Distribution of Decameter Scale (50 m) Ionospheric Irregularities at High Latitudes 

      Jin, Yaqi; Clausen, Lasse; Spicher, Andres; Ivarsen, Magnus Fagernes; Zhang, Yongliang; Miloch, Wojciech Jacek; Moen, Jøran Idar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-15)
      We present a study of decameter scale ionospheric irregularities using in-situ electron density data from the NorSat-1 satellite. During the current period of low solar activity, NorSat-1 frequently observes significant plasma irregularities from several 10 s km down to several decameter. These are often observed near the dayside cusp and dawnside auroral zone. The decameter-scale irregularities are ...
