    • First observation of the anomalous electric field in the topside ionosphere by ionospheric modification over EISCAT 

      Kosch, Michael; Vickers, Hannah; Ogawa, Yasunobu; Senior, Andrew; Blagoveshchenskaya, Natalya (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-10-24)
      We have developed an active ground-based technique to estimate the steady state field-aligned anomalous electric field (E*) in the topside ionosphere, up to ~600 km, using the European Incoherent Scatter (EISCAT) ionospheric modification facility and UHF incoherent scatter radar. When pumping the ionosphere with high-power high-frequency radio waves, the F region electron temperature is significantly ...

      The Antarctic and Arctic regions are Earth's open windows to outer space. They provide unique opportunities for investigating the troposphere–thermosphere–ionosphere–plasmasphere system at high latitudes, which is not as well understood as the mid- and low-latitude regions mainly due to the paucity of experimental observations. In addition, different neutral and ionised atmospheric layers at high ...
