Application of a Ground-Based Doppler LIDAR toAutomatic Windshear Alerting

摘要

A Doppler Light Detection And Ranging (LIDAR) system has been operated by the Hong Kong Observatory (HKO) for weather monitoring at the Hong Kong International Airport (HKIA) since 2002. Runway-dedicated LIDARs were deployed at the airport in late 2006. In the past 6 years or so, a number of aviation weather applications of the LIDAR have been developed by HKO to improve aviation safety. This paper aims to summarize the latest developments in the major application area of the LIDAR systems in HKIA, namely, automatic windshear alerting. The future development work for this application is also discussed.
