| 摘 要： | With the data of complex refractive index of sulfate aerosol,the radiative properties of theaerosol under 8 relative humidity conditions are calculated in this paper.By using the concentrationdistribution from two CTM models and LASG GOALS/AGCM,the radiative forcing due tohygroscopic sulfate aerosol is simulated.The results show that:(1)With the increase of relativehumidity,the mass extinction coefficiency factor decreases in the shortwave spectrum;singlescattering albedo keeps unchanged except for a little increase in longwave spectrum,andasymmetry factor increases in whole spectrum.(2)Larger differences occur in radiative forcingsimulated by using two CTM data,and the global mean forcing is—0.268 and—0.816 W/m~2,respectively.(3)When the impact of relative humidity on radiative property is taken into account,the distribution pattern of radiative forcing due to the wet particles is very similar to that of drysulfate,but the forcing value decreases by 60%.
