Paper Abstract

One year of continuous measurements of visibility, temperature and relative humidity at the Hong Kong International Airport at Chek Lap Kok (CLK) are combined with the concentrations of the respirable suspended particulates (RSP) measured in Tung Chung near the Airport to extract annual and seasonal characteristics of the aerosols. The knowledge of aerosol characteristics obtained is used in the development of inversion methods for aerosol extinction retrieval from Lidar data. In this paper, the details fo aerosol characteristics and retrieved aersosol extinction profiles are presented. This additional data product requires no additional hardware to the existing Lidar, but only additional computational research efforts. The knowledge of spatil aerosol distributions during haze episodes will be valuable to aviation meteorologists at Chek Lap Kok. Long term visibility studies using Lidar of this kind will help our understanding of the air pollution problem in a coastal urban city like Hong Kong.
