Overview of the Page venus-atm

Goal of Earth-based observations in the VEx-VCO/Akatsuki context

• Perform direct measurements not feasible by an orbiter

e. g. provide direct absolute wind measurements

• Obtain simultaneous measurements over several levels in Venus' upper atmosphere
• Obtain cross-validation of different measurement techniques
• Extended spatial (both hemispheres) and temporal scales
• Constrain modeling of the mesosphere, e.g. validity domain of cyclostrophic approximation
