Reprint 519 Application of LIDAR backscattered power to visibility monitoring at the Hong Kong International Airport: some initial results

Comparison of Aerosol Optical Depth (AOD) Derived from Ground-Based LIDAR and MODIS

The performance and application of AOD products from the Moderate Resolution Imaging Spectroradiometer (MODIS) are studied by comparing with the AOD derived from the ground-based Doppler LIDAR inside the Hong Kong International Airport (HKIA). The backscattered power data of the LIDAR are used to determine the extinction coefficient profile, from which the AOD is calculated. The AOD determined ...

Aviation Applications of the Pulsed Doppler LIDAR – Experience in Hong Kong

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 paper give...

Determination of Backscatter-Extinction Coefficient Ratio for LIDAR-Retrieved Aerosol Optical Depth Based on Sunphotometer Data

Backscattered power data from the Doppler LIght Detection And Ranging (LIDAR) systems at the Hong Kong International Airport (HKIA) could be used to obtain the extinction coefficient of the troposphere by combining with the meteorological optical range (MOR) data from the nearby forward scatter sensor. The Range-height Indicator (RHI) scan of the LIDAR is then utilized to derive the vertical pr...

Application of Short-Range LIDAR in Early Alerting for Low-Level Windshear and Turbulence at Hong Kong International Airport

Hong Kong Observatory currently uses a series of meteorological instruments, including long-range LIDAR (light detection and ranging) systems, to provide alerting services of low-level windshear and turbulence forHongKong International Airport. For some events that are smaller in spatial dimensions and are rapidly changing, such as low altitudewindshear and turbulence associatedwith buildings o...
