Abstract. We present the first measurements of simultaneous horizontal and vertical winds using a new lidar system developed at Leibniz Institute Atmospheric Physics in Kühlungsborn, Germany (54.12° N, 11.77° E), for concept Vertical And Horizontal COverage by LIdars (VAHCOLI). describe technical details multi-field-of-view (MFOV) upgrade, which allows measurement wind dynamics transition region from microscale to mesoscale (103–104 m). The method was applied edge developing high-pressure region, covering altitudes between 3 25 km. Comparisons data European Centre Medium-Range Weather Forecasts (ECMWF) show excellent agreement meridional component along north beam lidar, is better than 0.30±0.33 m s−1, while south beam, higher deviation with -0.93±0.73 s−1 observed. Measurements significant underestimation this ECMWF. Comparison Aeolus projected viewing direction shows good agreement, results -0.12±3.31 s−1. capability MFOV explore small-scale asymmetries field shown comparison view, where we observe asymmetry winds, also ECMWF but underestimated factor approximately 4.
