    • Challenges and Strategic Research Plans for Earth and Heliosphere: Research Infrastructures, Projects and Initiatives 

      Mann, Ingrid; Kauristie, Kirsti; Bamford, Ruth; McCrea, Ian; Moen, Jøran Idar; Oksavik, Kjellmar; Yamauchi, Masanori; Johnsen, Magnar Gullikstad; Turunen, Esa (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-24)
      We describe existing research infrastructures relevant for space weather and open issues of space weather research including the need for sustainable observation networks and for high-quality data products as basis for model development. The local relevance in Europe for studies of the ionosphere at high latitude is described. We propose as possible a way forward to sustain space weather research ...

    • Controlled beat-wave Brillouin scattering in the ionosphere 

      Eliasson, Bengt; Senior, A.; Rietveld, Michael T.; Phelps, A.D.R.; Cairns, R.A.; Ronald, K.; Speirs, D.C.; Trines, R.M.G.M.; McCrea, Ian; Bamford, R.; Mendonça, J.T.; Bingham, R. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-27)
      Stimulated Brillouin scattering experiments in the ionospheric plasma using a single electromagnetic pump wave have previously been observed to generate an electromagnetic sideband wave, emitted by the plasma, together with an ion- acoustic wave. Here we report results of a controlled, pump and probe beat-wave driven Brillouin scattering experiment, in which an ion-acoustic wave generated by the ...
