Abstract:Spring monthly AOD and dust-AOD from 2005 to 2007 were simulated by RegCM3, and simulated results were validated by observational data. Meanwhile, the contribution and influence of dust-sand aerosol and human emission aerosol on spring AOD was discussed. The results show that there were mainly three high-value AOD areas in spring, which were southern Sinkiang Basin and parts of northern Sinkiang, Gansu Corridor, and Sichuan Basin with its adjacent parts of central south China, and the anterior two high-value areas primarily caused by dust-sand aeroso lin comparison with the last one mainly affected by human activities aerosol. Furthermore, the validation used by observational data showed that the simulation results were creditable, and it revealed the simulation was better for human activity infrequent sites than for human activity frequent sites, urban sites and coastal sites. As more, the simulation value was lower than observation at urban sites and coastal sites, and the AOD differences were greater between simulation and observation at the most remote sites, such as Fukang, Haibei, Lhasa and Xishuangbanna.
