Production Introduction 聽 With the advanced scanning detection mode and wind field inversion algorithm, the 3D scanning wind lidar can be flexibly applied to the meteorological support service under complex terrain conditions. Leice provided the technical service of wind field monitoring on complex terrain in outdoor competition area of Beijing Winter Olympic Games. In Yanqing competition area of the 2022 Beijing Winter Olympic Games, the scanning wind lidar Wind3D 6000 had provided long-term and continuous high spatial resolution atmospheric wind field and turbulent flow field data under complex terrain of the venue. The accurate wind data contributes to the successful completion of the event. 聽 It provided fast tool for accurate observation of atmospheric wind field and turbulence field under complex terrain conditions. The observation data are assimilated into the weather forecast model to provide meteorological guarantee for the smooth running of the event and the safety of the participants. 聽 Leice's scanning wind lidars are featured of high temporal and spatial resolution, portable and movable observation, and adaptability to complex terrain. With the help of a variety of detection modes, such as 3D scanning, virtual tower, and multi lidar coordination, it can realize fully auto unattended observation of wind fields in complex terrain, and can effectively serve the wind observation and safeguard in big events. 聽 聽Customized Wind Lidars website:http://www.leicelidars.com/wind-lidars/
