Aviation applications of Doppler LIDAR – experience in Hong Kong
P. W. Chan, Hong Kong Observatory, Hong Kong, China; and C. M. Shun
The Hong Kong Observatory (HKO) introduced a Doppler LIDAR to the Hong Kong International Airport (HKIA) in 2002, the first LIDAR for aviation alerting services in the world. Since then, HKO has developed a number of weather products based on the LIDAR's velocity and backscatter power data. LIDAR is found to provide crucial information in a wide variety of aviation applications. This presentation gives a review of the experience in Hong Kong in the development of aviation-related weather products using the LIDAR data. Applications include: automatic windshear alerting from the HKO-developed glide-path scans, detection of low-level turbulence, 2D wind retrieval for intense convective events from LIDAR-radar dual Doppler analysis, 3D wind retrieval from a single LIDAR for terrain-disrupted airflow, visibility map based on backscatter power distribution in conical scans, and mixing-height monitoring in vertical scans. Future plan of LIDAR deployment at HKIA will also be discussed.
