• Solar Activity Driven 27‐Day Signatures in Ionospheric Electron and Molecular Oxygen Densities 

      Schmölter, ErikORCIDiD; von Savigny, ChristianORCIDiD (Journal of Geophysical Research: Space Physics, 2022-09-13)
      The complex interactions in the upper atmosphere, which control the height‐dependent ionospheric response to the 27‐day solar rotation period, are investigated with the superposed epoch analysis technique. 27‐day signatures ...
    • The Height‐Dependent Delayed Ionospheric Response to Solar EUV 

      Schmölter, ErikORCIDiD; Heymann, Frank; von Savigny, ChristianORCIDiD; Berdermann, JensORCIDiD (Journal of Geophysical Research: Space Physics, 2022-03-24)
      Based on the analysis of electron density Ne profiles (Grahamstown ionosonde), a case study of the height‐dependent ionospheric response to two 27‐day solar rotation periods in 2019 is performed. A well‐defined sinusoidal ...
