Abstract :
The aerosol optical depth of assimilated MODIS-GOCART in 2001 is used as continental aerosol (CA), black carbon (BC), and sulfate respectively. Their direct radiative forcing (RF) and regional climate effects over East of China are simulated using regional climate model. Comparison among three aerosols is also carried out. Negative RF at TOA for CA and sulfate is found as well as positive RF for BC, and it also reveals decrease of surface temperature and its daily range. Cloud can reduce RF of aerosols at both of solar and infrared bands.
