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
