Do Solar Energetic Particle (SEP) Events Influence the Formation of the V₀ Layer in the Venusian Ionosphere?

Choudhary, R. K.; Imamura, T.; Sánchez-Cano, Beatriz +2 more

This study investigates the potential impact of Solar Energetic Particles (SEPs) on the V₀ layer of the Venus ionosphere. Electron density profiles obtained from radio occultation experiments conducted by the Venus Express (VEX) and Akatsuki missions were utilized for this purpose. Background data from the Analyzer of Space Plasma and E…

Impact of the Turbulent Vertical Mixing on Chemical and Cloud Species in the Venus Cloud Layer

Marcq, Emmanuel; Stolzenbach, Aurélien; Lefèvre, Franck +3 more

The Venusian atmosphere hosts a 10 km deep convective layer that has been studied by various spacecrafts. However, the impact of the strong vertical mixing on the chemistry of this region is still unknown. This study presents the first realistic coupling between resolved small-scale turbulence and a chemical network. The resulting vertical mixing …
