Polar ionospheric currents and high temporal resolution geomagnetic field models
Kloss, Clemens; Finlay, Christopher C; Laundal, Karl Magnus; Olsen, Nils (Journal article; Peer reviewed, 2023)Estimating high resolution models of the Earth’s core magnetic field and its time variation in the polar regions requires that one can adequately account for magnetic signals produced by polar ionospheric currents, which ... -
An Updated Geomagnetic Index-Based Model for Determining the Latitudinal Extent of Energetic Electron Precipitation
Babu, Eldho Midhun; Nesse, Hilde; Hatch, Spencer Mark; Olsen, Nils; Salice, Josephine Alessandra; Richardson, Ian G. (Journal article; Peer reviewed, 2023)Energetic Electron Precipitation (EEP) from the Earth's plasma sheet and the radiation belts is an important feature of atmospheric dynamics through their destruction of ozone in the lower thermosphere and mesosphere. ...
