摘要
The direct radiative forcings due to tropospheric sulfate and fossil fuel soot aerosols are calculated. The change in the atmospheric sulfate since preindustrial time is taken from a recent three-dimensional chemistry transport model calculation. A multistream radiative transfer code and observed atmospheric input data is used. The direct radiative forcing due to sulfate is calculated to -0.32 W/m(2). Our results for global and annual mean radiative forcing have been compared with results from other model studies. We have assumed a linear relationship between the concentration of fossil fuel soot and sulfate aerosols. The resulting radiative forcing due to soot particles is 0.16 W/m(2). Two types of mixtures of sulfate and soot are further assumed. The calculated single scattering albedo is compared to observations.
