Instrumentation for a National Ultraviolet Radiation Calibration Facility

9420550 Deluisi科学界和广大公众对到达地球表面的太阳紫外线辐射增加的报告日益感到关切。尤其令人关切的是，由于平流层臭氧耗尽，造成生物破坏性的紫外线-B辐射增加。为了回应这些担忧，美国几个联邦机构正在开展紫外线监测和研究活动，以更好地了解紫外线辐射的趋势和影响。这些努力是通过制定美国机构间紫外线辐射监测计划来协调的。建立国家紫外线辐射校准设施对机构间努力至关重要。该设施的任务是确保利用该设施校准资源的网络存档的数据不会受到不同和模棱两可的校准的影响，这些校准可能会损害从使用数据得出的科学结论的有效性。该奖项为该设施的设备提供资金，该设施正通过国家科学基金会、环境保护局、美国农业部、国家标准与技术研究所以及国家海洋和大气管理局的努力得到支持。

9420550 Deluisi There is growing concern in the scientific community and the public at large regarding reports of increasing solar ultraviolet radiation reaching the Earth's surface. Of particular concern is the increase in biologically damaging ultraviolet-B radiation as a consequence of stratospheric ozone depletion. In response to these concerns, several U.S. federal agencies are conducting ultraviolet- monitoring and research activities to better understand trends and effects of ultraviolet radiation. These efforts are coordinated through the development of a U.S. interagency ultraviolet radiation monitoring plan. The establishment of a National Ultraviolet Radiation Calibration Facility is critical to the interagency efforts. The mission of the facility is to insure that the data archived by networks that utilize the facility's calibration resources will not suffer from disparate and ambiguous calibrations that could compromise the validity of scientific conclusions derived from the use of the data. This award provides funds for equipment for the facility, which is being supported through the efforts of the National Science Foundation, the Environmental Protection Agency, the United States Department of Agriculture, the National Institute of Standards and Technology, and the National Oceanic and Atmospheric Administration.
