U.S.-Denmark Program: Dissertation Research in Arctic Atmospheric Chemistry

9402512 Landsberger该奖项支持来自伊利诺伊大学厄巴纳-香槟分校Sheldon Landsberger博士的博士生在西欧进行的与论文相关的研究。研究生Steven Biegalski先生将在丹麦罗斯基勒的RISO国家实验室进行大气化学研究。兰茨伯格博士和比格尔斯基先生正在积极参与利用源-受体模型来描述北极空气中污染物特征的研究，同时也在研究卤素对臭氧破坏的影响。Landsberger博士获得了丹麦的资助，访问尼尔斯玻尔研究所的K. Heydorn博士和Kare Kemp博士，并与他们合作。他们正在指导一个丹麦项目，根据对北极气溶胶的分析开发受体模型。来自美国国家科学基金会西欧项目的资助将使Biegalski先生能够陪同Landsberger博士，并停留两个两个月的时间进行研究，这将有助于他的论文。参与RISO国家实验室正在进行的研究将使Biegalski先生能够接触到伊利诺斯大学没有的现场样品和专门的设备和程序。这将使他进一步了解大气气溶胶，特别是微量元素的远距离传输在全球变化中所起的作用。他还将在其研究生涯的早期阶段获得国际合作的经验，并与一个领先的大气化学研究小组及其欧洲合作者网络建立坚实的专业联系。＊＊＊

9402512 Landsberger This award supports dissertation-related research in Western Europe by a PhD student of Dr. Sheldon Landsberger from the University of Illinois at Urbana-Champaign. The graduate student, Mr. Steven Biegalski, will carry out atmospheric chemistry research at the RISO National Laboratory in Roskilde, Denmark. Dr. Landsberger and Mr. Biegalski are actively involved in research using source-receptor models to characterize the airborne pollutants in the Arctic and also to study the influence that halogens have on the destruction of ozone. Dr. Landsberger has received funding from Denmark to visit and collaborate with Dr. K. Heydorn and Dr. Kare Kemp of the Neils Bohr Institute. They are directing a Danish project to develop receptor models based on analyses of Arctic aerosols. Funding from the Western Europe Program of NSF will enable Mr. Biegalski to accompany Dr. Landsberger and to stay for two two-month periods to carry out research that will contribute to his dissertation. Participation in the ongoing research at RISO National Laboratory will give Mr. Biegalski access to field samples and specialized equipment and procedures not available to him at the University of Illinois. These will give him further insights into the role that the long range transport of atmospheric aerosols, particularly trace elements, play in global change. He will also gain experience in international collaboration at an early stage of his research career, and establish solid professional contacts with a leading atmospheric chemistry research group and its network of European collaborators. ***
