• A new Method for Estimating 3-Dimensional Ionospheric Currents from Ground-Based Magnetometers 

      Thom, Erik (Mastergradsoppgave; Master thesis, 2022-07-17)
      The ionosphere is a region of the upper atmosphere where a significant rate of photo-ionisation from solar ultraviolet radiation cause an increased plasma density. In this region a system of electrical currents flow, driven by electric fields generated by fluctuating dynamics within the Earths magnetosphere. These fluctuating dynamics are caused by interactions between the magnetosphere and the solar ...
