Long and Medium-Term Research: High Resolution Doppler Lidar System for Ground Based Wind Measurement of the MiddleAtmosphere

中长期研究：高分辨率多普勒激光雷达地面中层大气风测量系统该奖项是国外卓越中心长期和中期研究计划的一部分。它使美国科学家和工程师能够在国外公认的卓越研究中心进行三到十二个月的研究。该计划的奖励为联合研究提供了机会，并利用独特或互补的设施、专业知识和国外的实验条件。该奖项将支持密歇根大学安娜堡分校的Bruno Nardi博士和Marie-Lise Chanin博士在法国国家科学研究中心进行为期12个月的博士后研究访问。研究人员将建立一个可操作的多普勒激光雷达系统，以测量中层大气10-60公里高度范围内的风。这项法国的新技术是唯一一种获得中层大气连续风测量的地面方法，具有很高的空间和时间分辨率。要了解这个监测不足的大气区域的动力学及其与邻近大气区域的动力学耦合，风测量是必要的。除了参与该仪器的建设，Nardi博士将帮助开发和实施分析技术，并参与美国和法国的合作努力，以验证高分辨率多普勒干涉仪ıHRDI！目前在密歇根大学空间物理研究实验室的最后准备阶段，将被部署在高层大气研究卫星ıUARS！奖学金建议提供国际旅行费用和美国本土机构250美元的固定行政津贴。

Long & Medium-Term Research: High Resolution Doppler Lidar System for Ground Base Wind Measurement of Middle Atmosphere This award is under the Program for Long-& Medium Term Research at Foreign Centers of Excellence, which enables U.S. scientists and engineers to conduct three to twelve months of research abroad at research centers of proven excellence. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad. This award will support a twelve-month postdoctoral research visit by Dr. Bruno Nardi of the University of Michigan Ann Arbor with Dr. Marie-Lise Chanin at the Service d'A>ronomie of the Centre National de la Recherche Scientifique. The researchers will build an operational Doppler lidar system to measure wind in the 10-60 km altitude range of the middle atmosphere. This new French technique is the only ground- based method of obtaining continuous wind measurements in the middle atmosphere with very high spatial and temporal resolution. Wind measurements are necessary to understand the dynamics of this poorly monitored atmospheric region and its dynamic coupling to adjoining atmospheric regions. Besides participating in the construction of this instrument, Dr. Nardi will help develop and implement analysis techniques, and participate in a collaborative American-French effort to validate the High Resolution Doppler Interferometer ıHRDI!, now in the final stages of preparation at the Space Physics Research Laboratory at the University of Michigan, to be deployed in the Upper Atmosphere Research Satellite ıUARS!. The award recommendation provides funds to cover international travel and a flat administrative allowance of $250 for the U.S. home institution.
