Carbonaceous aerosol is one of the main ingredients of the atmospheric aerosol, which includes black carbon and organic carbon. The numerical simulations from 1960 to 2000 are aimed at the direct radiative effects on climate induced by carbonaceous aerosol in East Asia using NCAR Community Atmospheric Model version 3.1 (CAM). The mean radiative forcing(RF) under all sky in Chinese mainland at TOA and surface are 0.38 and -5.31W/m(2) respectively. This distinct RF leads to -0.1K surface temperature decrease in Chinese mainland, which includes -0.26K drop of daily maximum and 0.07K rise of minimum temperature. Air column temperature has also been increased 0.11K in Chinese mainland. Significant vapor and precipitation increase can be resulted from RF of carbonaceous aerosol in north China and the Yellow and Huai River basin, accompanied by the decrease in northeast China, far-east region, and Tibet Plateau.
