AN AEROSOL POLLUTION EPISODE IN HONG KONG WITH REMOTE SENSING PRODUCTS OFMODIS AND LIDAR

Aerosol optical depth data from MODIS visual channels and aerosol extinction coefficient profiles from MPL LIDAR are used to study an aerosol pollution episode in the Pear River Data on June 18 and 19, 2003. The regional distribution pattern of aerosol optical depth and the evolution of aerosol extinction coefficient profiles in mixing layer form remote sensing methods are given to demonstrate that the air pollution case caused by weak stable high system has a regional coverage and contributes to the surface air pollution in Hong Kong. The results show that satellite and LIDAR remote sensing provide new ways in air pollution study.
