Global distributions of aerosol optical thickness and Ångstrom exponent and cloud optical thickness and effective radius were obtained from satellite remote sensing and climate models. Ground-based chemical and radiative measurements were also performed to derive the optical thickness and the single scattering albedo of aerosols. These results show that characteristic distributions of industrial aerosols, biomass burning aerosols and so on. Resulted values of radiative forcing of the direct and indirect forcing of aerosols are from -0.1W/m2 to -0.2W/m2 and from -0.7W/m2 to -1.7W/m2, respectively

从卫星遥感和气候模式获得了全球气溶胶光学厚度和Ångstrom指数以及云光学厚度和有效半径的分布。还进行了地面化学和辐射测量，以求出气溶胶的光学厚度和单次散射反照率。这些结果显示了工业气溶胶、生物质燃烧气溶胶等的特征分布。气溶胶直接强迫和间接强迫的辐射强迫结果值分别为-0.1W/m2到-0.2W/m2和-0.7W/m2到-1.7W/m2
