Abstract

An improved scheme has been developed to retrieve volume fraction of aerosol chemical composition like black carbon (BC), mineral dust (DU), ammonium sulfate-like (AS) and water content from aerosol complex refractive indices and size distribution remotely obtained from ground-based sun-sky radiometer measurements. Typical observations in Beijing during 2011 were selected to investigate chemical composition retrieval results at clear, haze and dusty days respectively. The retrieved BC mass concentration was compared with coincident aethalometer.
