    • Electrojet Estimates From Mesospheric Magnetic Field Measurements 

      Laundal, Karl Magnus; Yee, J.H.; Merkin, V.G.; Gjerløv, Jesper; Vanhamäki, H.; Reistad, Jone Peter; Madelaire, Michael; Sorathia, K.; Espy, Patrick Joseph (Journal article; Peer reviewed, 2021)
      The auroral electrojet is traditionally measured remotely with magnetometers on ground or in low Earth orbit (LEO). The sparse distribution of measurements, combined with a vertical distance of some 100 km to ground and ...

    • External and Internal Causes of the Stormtime Intensification of the Dawnside Westward Auroral Electrojet 

      Ohtani, S.; Sorathia, K.; Merkin, V.G.; Frey, H.U.; Gjerløv, Jesper (Journal article; Peer reviewed, 2023)
      The dawn-dusk asymmetry of magnetic depression is a characteristic feature of the storm main phase. Recently Ohtani (2021, https://doi.org/10.1029/2021JA029643) reported that its magnitude is correlated with the dawnside ...

    • Local Mapping of Polar Ionospheric Electrodynamics 

      Laundal, Karl Magnus; Reistad, Jone Peter; Hatch, Spencer Mark; Madelaire, Michael; Walker, Simon; Hovland, Amalie Øie; Ohma, Anders; Merkin, V.G.; Sorathia, K.A. (Journal article; Peer reviewed, 2022)
      An accurate description of the state of the ionosphere is crucial for understanding the physics of Earth's coupling to space, including many potentially hazardous space weather phenomena. To support this effort, ground ...
