Abstract: Asia is one of the major sources of both natural (Asian dust) and anthropogenic aerosols in the world. Asian dust that is a typical example of mineral aerosols occurs in northern China, Mongolia and central Asia of the arid and semi-arid desert regions more frequently during the spring season due to desertification in some of source regions and has its increasing occurrence trend. Anthropogenic aerosols that are mainly originated from human activities and the formation by gas-to-aerosol conversion of pollutant have also an increasing trend due to the rapid economic expansion in many Asian countries especially in China. Therefore, atmospheric aerosols in the Asian region are the complex mixture of various aerosols such as Asian dust and anthropogenic aerosols. Atmospheric aerosols can affect the quality of our lives significantly because of its potential impacts on human health and the environment. The sub-micrometer size of aerosols can be inhaled and may pose certain health hazards. Because aerosols also scatter and absorb radiation they strongly influence the radiative budget of the Earth-Atmosphere system; they also reduce visibility and diminish the aesthetic scenery. Depositions of aerosols can affect significantly the terrestrial and marine ecologies. However, all these effects are not clearly quantified due to the lack of statistical aerosols data.
The Aerosol Modeling System(AMS) composed of the Asian Dust Aerosol Model2 (ADAM2) for the Asian dust aerosol modeling and the Community Multi-scale Air Quality (CMAQ) model for the anthropogenic aerosol modeling has been employed to provide the spatial distributions of all kinds of aerosols (Asian dust, Secondary inorganic aerosol(SIA), Secondary organic aerosol(SOA), organic carbon(OC), Black carbon(BC), sea salt and emitted PM10) in Asia for the whole year of 2010. The simulated results can be used for the impact assessment of aerosols on the environment. The AMS model and the model results are to be discussed in this presentation.

Brief Biography of the Speaker: Dr. Soon-Ung Park holds a BSc in Meteorology from the Seoul National University in Korea, an MSc in Meteorology from the University of Wisconsin-Madison in USA and a PhD in Atmospheric Sciences from Oregon State University in USA. He worked as a Research Associate and an Assistant Professor in University of Wisconsin-Milwaukee in USA (1978-1981). Since 1981, he had been served at the Department of Atmospheric Sciences of Seoul National University in Korea as an Assistant Professor, Associate Professor and Professor before he retired from Seoul National University in 2006. As a Professor Emeritus of Seoul National University, he founded “Center for Atmospheric and Environmental Modeling (CAEM)” in 2006 to pursue further studies on Atmospheric Environmental Issues including air pollution dispersion, anthropogenic aerosols, dust aerosols, acidic rain and carbon cycles in the forests. He has developed an operational Asian Dust Aerosol Model 2 (ADAM2) that is now used as an Asian dust forecasting model in Korea Meteorological Administration (KMA). He is interested in the development of an Aerosol Modeling System that includes both dust aerosols and anthropogenic aerosols. He has published more than 200 papers in major reviewed journals, more than 150 in conference proceedings and more than 100 granted technical reports. Recently he served as a chairman of Asian Node of World meteorological Organization (WMO) Sand and Dust Storm Warning and Assessment System (SDS-WAS) from 2008 to 2012. He is now the Director of CAEM and a committee member of Regional Steering Group WMO SDS-WAS. He had been awarded an Academic Prize and a Distinguished Service Medal from Korean Meteorological Society, Letter of Commendations by President of Korea, Minister of Science and Technology of Korea and Minister of Education of Korea. He had received Seoul Citizen Cultural Prize by Mayor of Seoul and A Distinguished Service Red Color Decoration by the Republic of Korea. He had been cited 2000 outstanding scientists of the 21 century by American Biographical Institute and International Biographical Center, Cambridge, England.
