Short-range LIDAR

Short-range LIDAR

With the continuous development of the airport, the possibility of turbulence arising from buildings near the runway has gained attention. To address this issue, the Observatory developed alerting technology based on the short-range LIDAR (SRL), and installed a unit of SRL (Figure 1) close to the North Runway near to AsiaWorld-Expo. With its finer and more frequent scans, the SRL can help capture turbulence features, which are of smaller spatial and temporal scales, induced by buildings nearby.
 
The SRL has commenced operational use since the middle of 2019 as an enhancement of the Observatory’s Windshear and Turbulence Warning System.
