Ultraviolet Radiation in the Arctic

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该奖项将支持在阿拉斯加州巴罗和格陵兰岛萨米特的紫外线光谱辐照度监测网络（UVSIMN）站点继续进行紫外线辐射测量。UVR自1990年以来一直在巴罗测量，自2004年以来一直在萨米特测量。UVSIMN是对北极观测网络和北极环境变化研究的贡献。拟议项目的关键“知识价值”集中在获取可用于推进以下知识的数据上：（1）北极现在和未来的太阳辐射气候;（2）驱动紫外线辐射变化的因素。例如，通过将UVR数据与其他测量和建模相结合，可以开发参数化来预测未来的UVR强度并改进气候模型（例如，CCM）。这项活动的“更广泛影响”是向各学科的研究人员提供数据，包括卫星地面实况调查，并向教育工作者提供数据，用于科学课程和教学大纲。芝加哥大学的本科生将参与数据处理和质量评估/控制。与格雷厄姆通识教育学院合作，PI将为芝加哥公立学校的教师提供暑期课程，这些学校的入学人数主要是少数民族。课程将涉及极地地区的大气和环境研究，材料将部分取自拟议项目的成果。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This award will support the continuation of UVR (ultra-violet radiation) measurements at the Ultraviolet Spectral Irradiance Monitoring Network (UVSIMN) sites at Barrow, Alaska, and Summit, Greenland. UVR has been measured at Barrow since 1990 and at Summit since 2004. The UVSIMN is a contribution to the Arctic Observing Network (AON) and the Study of Environmental Arctic Change (SEARCH). The key "Intellectual Merit" of the proposed project centers on acquiring data that can be used to advance knowledge of (1) the present and future solar radiation climate of the Arctic and (2) the factors that drive changes in UVR. For example, by combining UVR data with other measurements and modeling, parameterizations can be developed to predict future UVR intensities and improve climate models (e.g., CCMs). The "Broader Impacts" of this activity are to provide data to researchers in various disciplines, including satellite ground-truthing, and to educators for use in science courses and curricula. Undergraduate students at the University of Chicago will be involved in data processing and quality assessment/control. In collaboration with the Graham School of General Studies, the PI will provide summer courses for teachers in Chicago public schools where enrollments consist predominantly of minorities. Courses will be related to atmospheric and environmental research in the Polar Regions, and material will partly be drawn from results of the proposed project.
