Abstract
Turbulence could increase the workload of pilots, and timely provision of turbulence information would be beneficial to aircraft operation. This paper summarises the use of a Doppler Light Detection and Ranging (LIDAR) system to measure turbulence intensity at an operating airport. The cube root of eddy dissipation rate (EDR) is used for representing the turbulence intensity, according to the requirement of the International Civil Aviation Organization (ICAO). The quality of EDR so calculated is established by comparing with the aircraft data. Examples of EDR maps based on conical scans of the LIDAR are presented. The EDR maps so obtained should be useful for aviation operations, and the EDRs calculated from the glide-path scans of the LIDAR may be used for turbulence alerting applications.
