   Sammanfattning : Sporadic-E layers (Es) are layers of metallic ions that appear in the lower E-region of the ionosphere and can last from under one hour to several hours. Es are found at all latitudes, but polar cap Es, and specifically over Svalbard at a latitude of around 78◦ , are the focus of this study. LÄS MER

3. 2. On the Relationship Between Energetic Electron Precipitation and Mesopause Temperature

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Florine Enengl; [2019]
   Nyckelord :;

   Sammanfattning : Energetic Particle Precipitation (EPP) can potentially change the neutral atmospheric temperatureat the mesopause region. Cresswell-Moorcock et al. (2013) used European IncoherentScatter Scientific Association (EISCAT) radar data to identify strong electron precipitationevents. LÄS MER
