SGER: Recent Changes of Solar Ultraviolet Radiation in the Arctic

该合同将支持在2009年5月31日之前在阿拉斯加Barrow和格陵兰Summit继续进行紫外线和可见光太阳辐照度观测，并随后处理完全校准的数据，提交给世界臭氧和紫外线辐射数据中心（WOUDC）和北极观测网络（AON）的合作北极数据和信息服务（CADIS）。这些观测将在Barrow（1990年开始数据采集）和Summit（2004年开始数据采集）保持完全校准的紫外线和可见光太阳辐照度数据的完整记录。向数据中心提交数据将确保这些数据能够免费和公开地提供给科学界和其他有关方面。巴罗和顶峰观测点是美国国家科学基金会紫外线光谱辐照度监测网（UVSIMN）的一部分，该网络支持研究平流层臭氧消耗和其他气候因素对地球表面紫外线辐射的影响，以及对水生和陆地生态系统以及人类的影响。更广泛的影响包括为教育工作者、研究人员和政策制定者提供数据，例如通过持续贡献评估报告。

This award will support continued UV and visible solar irradiance observations at Barrow, Alaska, and Summit, Greenland, until 31 May 2009, and subsequent processing of fully calibrated data for submission to the World Ozone and Ultraviolet Radiation Data Centre (WOUDC) and the Cooperative Arctic Data and Information Service (CADIS) of the Arctic Observing Network (AON). The observations will maintain unbroken records of fully calibrated UV and visible solar irradiance data at Barrow, where data acquisition began in 1990, and at Summit, where data acquisition began in 2004. Submission of data to the data centers will ensure that they are freely and openly available to the scientific community and other interested parties. The Barrow and Summit observing sites are part of the NSF Ultraviolet Spectral Irradiance Monitoring Network (UVSIMN) that has supported research into the effects of stratospheric ozone depletion and other climatic factors on UV radiation at the Earth's surface, and consequences for aquatic and terrestrial ecosystems, and people. The broader impacts include the provision of data to educators, researchers, and policy makers, for example through continued contributions to assessment reports.
