    • Determining Latitudinal Extent of Energetic Electron Precipitation Using MEPED On-Board NOAA/POES 

      Babu, Eldho Midhun; Tyssøy, Hilde Nesse; Smith-Johnsen, Christine; Maliniemi, Ville Aleksi; Salice, Josephine Alessandra; Millan, R.M.; Richardson, I.G. (Journal article; Peer reviewed, 2022)
      Energetic Electron Precipitation (EEP) from the plasma sheet and the radiation belts ionizes the polar lower thermosphere and mesosphere. EEP increases the production of NOx and HOx, which will catalytically destroy ozone, ...

    • Energetic Electron Precipitation During Slot Region Filling Events 

      Nesse, Hilde; Babu, Eldho Midhun; Salice, Josephine Alessandra; Funke, B. (Journal article; Peer reviewed, 2023)
      The slot region marks the equatorward boundary of the energetic electron precipitation (EEP). There are, however, numerous reports where energetic electrons cross these boundaries and fill the slot region. The ensuing EEP ...

    • Exploring the Predictability of the High-Energy Tail of MEE Precipitation Based on Solar Wind Properties 

      Salice, Josephine Alessandra; Nesse, Hilde; Babu, Eldho Midhun; Smith-Johnsen, Christine; Richardson, Ian (Journal article; Peer reviewed, 2023)
      Medium Energy Electron (MEE) precipitation (≳30 keV) ionizes the mesosphere and initiates chemical reactions, which ultimately can reduce mesospheric and stratospheric ozone. Currently, there are considerable differences ...

    • Modelling the Spatial Extent of Medium Energy Electron Precipitation 

      Babu, Eldho Midhun (Doctoral thesis, 2023-09-22)
      Jordens magnetosfære fungerer som et robust skjold, og beskytter planeten vår mot den nådeløse tilstrømningen av ladede partikler som hovedsakelig stammer fra solens solvind og fra de kosmiske strålene utenfor vårt solsystem. ...

    • The Predictive Capabilities of the Auroral Electrojet Index for Medium Energy Electron Precipitation 

      Tyssøy, Hilde Nesse; Partamies, Noora; Babu, Eldho Midhun; Smith-Johnsen, Christine; Salice, Josephine Alessandra (Journal article; Peer reviewed, 2021)
      The chemical imprint of the energetic electron precipitation on the atmosphere is now acknowledged as a part of the natural forcing of the climate system. It has, however, been questioned to which degree current proxies ...

    • 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. ...
