Sulfate aerosol is of great importance to the energy balance and global climate change of the earth system. Based on SO_2 emission inventory of China in 2007,this study presents both seasonal and spatial distributions of direct radiative effect( DRE) of sulfate aerosols in China using Can METOP,OPAC and SBDART models. The DRE of sulfate aerosols in China varied between- 9. 1 ~ 0. 0008 W·~(m~(-2))with the average DRE of- 1. 372 W·~(m~(-2))in2007,which was much larger than that in the world( annual average DR...
