Relation between aerosol characteristics and impact factor on climate and environment

Aerosol impacts on Earth's system are not negligible. The change of concentration of aerosols causes various effects on the climate by directly and indirectly modifying the optical properties and lifetimes of cloud. In addition to radiation budget change, aerosol has a significant potential to change cloud and precipitation. East Asia is the area with high concentration of aerosols in the world. This work intends to investigate distribution of aerosols over East Asia and estimate impacts of aerosol on regional climate change using by satellite data and GCM simulations. Aerosol impacts on climate over East Asia is larger than global mean. The simulated results show that surface cooling and weaken monsoon circulation by aerosol effects.
