摘要: 利用2003年9月-2004年12月天空辐射计观测数据初步反演得到了北京地区大气气溶胶光学特性的参数,包括:500 nm大气气溶胶光学厚度,Angstrom波长指数,单次散射反照率和粒子谱分布的季节变化特征。将反演得到的结果代入辐射传输模式,计算北京地区大气层顶和地面在晴空条件下大气气溶胶的辐射强迫,并分析了其季节变化特征。

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
