Lately, Kunlong AG600, a large amphibious aircraft for fire fighting and water rescue, has made its first flight at sea in Qingdao. The doppler wind lidar developed by LEICE Transient provides meteorological support for the scientific research and first flight test at sea. LEICE's Wind3D 6000 wind lidar provides real-time three-dimensional wind field information of take-off and landing area, which makes up for the deficiency of existing offshore wind field detection ability and fully meets the monitoring requirements.
