Abstract

Abstract: The aerosol optical properties have been retrieved from skyradiometer observation data. Seasonal variations of aerosol optical properties including Aerosol Optical Depth (AOD), Angstrom exponent (alpha), Single Scattering Albedo (SSA), volume size distribution have been analyzed. These retrieval results are inputted into a radiation transfer model and aerosol radiative forcing (ARF) under clear sky condition at Top of Atmosphere (TOA) and surface are calculated over Beijing. The seasonal variation of ARF is discussed.

Key words: Skyradiometer, Aerosol, Optical properties, Radiative forcing
