To fully understand atmospheric dynamics, climate studies, energy transfer, and weather prediction the wind field is one
of the most important atmospheric state variables. Studies indicate that a global determination of the tropospheric wind
field to an accuracy of 0.5 m/s is critical for improved numerical weather forecasting. LEOSPHERE recently developed
a new generation long range compact, eye safe and transportable wind Lidar, named WLS70, capable to fully determine
locally the wind field in real time in the planetary boundary layer (PBL). First results of the measurement campaign put
in evidence both wind velocity vertical profiles and atmosphere structure derived from Lidar data.
