Abstract. We present the first measurements of simultaneous horizontal and vertical winds using a new VAHCOLI lidar system developed at the Leibniz Institute for Atmospheric Physics in Kühlungsborn, Germany (54.12° N, 11.77° E). We describe the technical details of a multi-field-of-view (MFOV) upgrade, which allows to measure wind dynamics in the transition region from microscale to mesoscale (103−104 m). The method was applied at the edge of a developing high-pressure region. Comparisons between the lidar measurements and data from ECMWF show excellent agreement for the horizontal wind components, better than 0.30 ± 0.36 m s−1 along the north beam of the lidar and −0.93 ± 0.73 m s−1 along the south beam. Measurements of vertical wind show significant underestimation of this component by ECMWF. Comparison to ADM-Aeolus shows good agreement, better than −0.12 ± 3.31 m s−1. The capability of the MFOV lidar to explore small-scale asymmetries in the wind field is shown by comparison of the north and south field of view, where we observe a wind asymmetry in the meridional winds, which is also present in ECMWF but underestimated by a factor of approximately four.

Short summary
A novel lidar system with five beams measured horizontal and vertical winds together for the first time. Developed in Germany, it revealed accurate horizontal wind data compared to forecasts, but vertical wind estimates differed. The lidar's capability to detect small-scale wind patterns was highlighted, advancing atmospheric research.
