U.S.-Korea Cooperative Research on The Long Range Transport of Pollutants in the Pacific Rim Region Around South Korea

本提案请求资金允许爱荷华大学化学与生物工程系Gregory R. Carmichael博士与韩国亚洲大学环境工程系Min Sun Hong博士进行为期24个月的研究。这是一个关于韩国周围环太平洋地区空气污染物远距离输送的合作研究项目。研究计划包括观察和建模两部分。将在位于韩半岛西南偏南的济州岛进行气溶胶、臭氧、氮氧化物和硫氧化物的背景测量。将对污染物的远距离迁移及其对环境的影响进行全面的模拟分析。释放到大气中的化学物质会对环境产生许多不利影响，包括烟雾等局部空气污染，酸雨等区域性问题，以及平流层臭氧减少和全球变暖等全球性问题。韩国位于中国西部和日本东部之间，为研究东亚地幔柱的运输和化学特性提供了理想的位置。这项研究对美国来说很有意义，也很有益，因为现在已经确定污染物及其影响并不局限于化学物质进入大气的地方。两位研究员都是该项目领域的杰出科学家，他们在之前的研究中有过成功的合作记录。该项目与美韩合作科学项目的目标相关，该项目旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作，提高美韩科学家和工程师之间的合作水平。洪博士参与该项目得到了韩国科学与工程基金会（KOSEF）的支持。

This proposal requests funds to permit Dr. Gregory R. Carmichael, Department of Chemical and Biological Engineering, University of Iowa, to pursue with Dr. Min Sun Hong, Department of Environmental Engineering, Ajou University, Korea, for a period of 24 months, a program of cooperative research on the long range transport of air pollutants in the Pacific Rim region around South Korea. The research plan includes observation and modelling components. Background measurements of aerosol, ozone, and oxides of nitrogen and of sulfur will be obtained at Cheju Island located south-southwest of the Korean peninsula. Comprehen- sive modelling analysis of the long range transport of pollutants and their impact on the environment will be made. Chemicals released into the atmosphere can have many adverse impacts on the environment including local air pollution such as smog, regional problems such as acid rain, and global problems including the reduction of stratospheric ozone and global warming. South Korea's location between China, to the west, and Japan, to the east, provides an ideal location to study the transport and chemical charac- teristics of the east Asia plume. This research is of interest and benefit to the United States because it has now been well established that neither pollutants nor their effects are confined to the locations where the chemicals enter the atmosphere. The two investigators are outstanding scientists in the field of the project who have a record of successful collaboration in prior research. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. Dr. Hong's participation in the project is supported by the Korea Science and Engineering Foundation (KOSEF).
