The estimation of radiative forcing to atmospheric aerosols is considered more complex and larger uncertainties than greenhouse gases. This situation is mainly due to the complexity of aerosol radiative forcing mechanism and the lack of detailed information of aerosol properties, such as size distribution, chemical composition, atmospheric transport and removal processes, etc. East Asia is one of the major sources of wind-blown dust in the world, however, up to date the studies on the dust aerosol fro...
