Paper Abstract

A sky radiometer has been operated in Hong Kong since the beginning of 2002. The seven wavelengths intensities were taken at intervals throughout the day. Inversions were made to retrieve the aerosol column volume concentrations of different aerosol radii. In this paper we presented some monthly averaged results of aerosol optical properties such as single scattering albedo, and optical refractive index. Examples of consecutive measures of the column aerosol properties are given to illustrate the change of air masses -- maritime, continental and urban -- over Hong Kong. Monitoring aerosol properties using sky radiometer has been found to be effective and efficient.
