Generation of eddy dissipation rate map at the Hong Kong International Airport based on Doppler LIDAR data
The EDR map is calculated based on plan-position indicator (PPI) scans of the LIDAR. The whole scan area is divided into a number of small sectors, each having a size of about 1 km in range and 20 degrees in azimuth. Velocity structure function is evaluated in every sector and compared with the theoretical von Kármán model to estimate the EDR. This paper gives an overview of the calculation method, shows some examples of EDR map in terrain-disrupted turbulent airflow at HKIA and examines the quality of the EDR value so obtained by comparing against the measurements of a ground-based anemometer.
