What the literature leaves open

  • The lack of a mechanistic understanding of the ionosphere. The need for a systematic assessment of how solar flux, geomagnetic activity, and spatiotemporal coordinates shape the electronic density profile.

    From prediction to mechanistic understanding: SHAP-based interpretation of a low-latitude ionospheric three-dimensional electron density model · 2026 · DOI

  • The long-standing question of the reliability of the vertical wind in multistatic meteor radar networks remains unresolved. Previous implementations of Volume Velocity Processing have limitations, such as projection errors resulting from an incomplete representation of the observation geometry. There is a need for accurate estimation of three-dimensional wind fields in the mesosphere and lower thermosphere.
