We present first-time estimation of the meridional wind in both hemispheres on Venus. Wind measurements from VEx/VIRTIS coordinated with Ground-based Doppler velocimetry results. Spatial and temporal variability of the zonal flow with latitude and local time. Confirmation of the coherence, and complementarity, in cloud-tracked and Doppler winds results. We show a summary of coordinated CFHT/ESPaDOnS and VEx/VIRTIS simultaneous observations.
