A comparative study on the aerosol optical properties of two severe pollution phenomena occurred in Beijing, i.e.dust and haze-fog, was analyzed using solarand sky radiance measurements from 2001 to 2007.The aerosol optical depth (AOD) showed a distinct variation under different weather conditions,with an average 1.70 in dust days and 1.26 in haze-fog days.
