The awardee will operate and manage the Poker Flat and Resolute Bay Advanced Modular Incoherent Scatter Radar (AMISR) facilities. AMISR is a new incoherent scatter radar system designed and built through National Science Foundation support. Over the last four decades, incoherent scatter radar is the primary technique for measuring basic properties of the upper atmosphere and ionosphere. The AMISR has significant scientific advantages over existing incoherent scatter radars, largely due to the rapid steering provided by the phased array antenna. The pulse-to-pulse steering capability promises to resolve many of the temporal/spatial ambiguities inherent in measurements from mechanically steered dish-based systems. In operating and managing the AMISR systems in Alaska and Canada, the awardee will focus on assisting the research community by 1) directing use of a state-of-the-art facility in unique parts of the world, 2) providing access to a knowledgeable staff of scientists and engineers for consultation and collaboration, 3) providing logistics support for campaigns and long-term measurement programs, 4) providing easy access to various levels of processed and analyzed radar data, and 5) participating in the training of students and assisting student advisors. Scientific activities related to the AMISR observations will focus on Earth's upper atmosphere, ionosphere, and magnetosphere, and their coupling to the solar wind. Although, knowledge of the Earth's geospace environment has advanced significantly during the second half of the twentieth century, detailed understanding of even the most basic processes remains somewhat vague. At times, important temporal scales can range from seconds through days. Similarly, the relevant spatial scales range from submeters through thousands of kilometers. AMISR fills the needs of the atmospheric science and magnetospheric science communities to study the dynamic processes that occur at high latitudes. There is evidence that much of the variability is due to advection of horizontally inhomogeneous structures, but it is also clear that the structures evolve with time. A phased array system such as AMISR would essentially support the short timescale imaging of such structures and the tracking of their evolution. A similar argument applies to the probing of auroral ionization structures. Another important attribute of the AMISR facilities is that they are remotely accessible, and the radar and ancillary instruments will be designed to produce real-time processed data that will be made publicly available and distributed to the user community over the Internet. The provision of user-friendly data and display capabilities, which meet the community's research needs, is an important part of AMISR operations. Support of a strong, distributed, and trained user community is very important to the overall scientific success of the AMISR project. The AMISR management team will work directly with graduate and undergraduate students and their advisors to assist with student training, experiment planning, and scheduling. It will also maintain a repository for contributed course materials, technical data, and facility instrument information.

获奖者将操作和管理扑克平台和Resolute湾先进模块化非相干散射雷达（AMISR）设施。AMISR是一种新的非相干散射雷达系统，由美国国家科学基金会支持设计和建造。在过去的四十年里，非相干散射雷达是测量高层大气和电离层基本特性的主要技术。与现有的非相干散射雷达相比，AMISR具有显着的科学优势，这主要是由于相控阵天线提供的快速转向。脉冲到脉冲的转向能力有望解决许多时间/空间的模糊性固有的测量从机械转向盘为基础的系统。在阿拉斯加和加拿大运营和管理AMISR系统时，获奖者将专注于通过以下方式协助研究界：1）指导在世界独特地区使用最先进的设施，2）提供知识渊博的科学家和工程师进行咨询和合作，3）为活动和长期测量计划提供后勤支持，4）提供方便地访问各种级别的处理和分析的雷达数据，以及5）参与学生的培训和协助学生顾问。与AMISR观测有关的科学活动将侧重于地球高层大气、电离层和磁层及其与太阳风的耦合。虽然在二十世纪后半叶，对地球地球空间环境的了解有了很大的进展，但即使是对最基本的过程的详细了解仍然有些模糊。有时，重要的时间尺度可以从几秒到几天不等。同样，相关的空间尺度从亚米到数千公里不等。AMISR满足了大气科学和磁层科学界研究高纬度动态过程的需要。有证据表明，大部分的变化是由于平流的水平不均匀的结构，但它也很清楚，该结构随时间而演变。一个相控阵系统，如AMISR将基本上支持这种结构的短时间尺度成像和跟踪其演变。类似的论点也适用于极光电离结构的探测。AMISR设施的另一个重要特点是可以远距离使用，雷达和辅助仪器的设计将能产生实时处理的数据，这些数据将公开提供，并通过因特网分发给用户。提供用户友好的数据和显示能力，满足社区的研究需要，是AMISR业务的重要组成部分。一个强大的，分布式的，训练有素的用户社区的支持是非常重要的AMISR项目的整体科学成功。AMISR管理团队将直接与研究生和本科生及其顾问合作，协助学生培训，实验规划和日程安排。它还将维持一个存放所提供的课程材料、技术数据和设施仪器信息的资料库。
