The investigators will operate and manage the Poker Flat and Resolute Bay Advanced Modular Incoherent Scatter Radar (AMISR) facilities. This effort continues facility operations and community support from the past five years, focused on assisting the research community by 1. directing use of state-of-the-art facilities in unique parts of the world, 2. providing access to a 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. Knowledge of the Earth's upper atmosphere, ionosphere, and geospace environment has advanced significantly during the second half of the twentieth century due in large part to the use of incoherent scatter radars (ISRs). A detailed understanding of even the most basic processes remains somewhat vague, however, because such an understanding must encompass the strongly coupled systems of the Earth's upper atmosphere, ionosphere, magnetosphere, and the solar wind. At times, important temporal scales can range from seconds through days. Similarly, the relevant spatial scales range from sub-meters to thousands of kilometers. The AMISR radars have significant scientific advantages over existing ISRs, largely due to the rapid steering provided by the phased array antenna. This pulse-to-pulse steering capability can be exploited to resolve many of the temporal/spatial ambiguities inherent in measurements from mechanically steered dish-based systems. A phased array system enables the short timescale, three-dimensional imaging of ionospheric structures and the tracking of their evolution. Perhaps even greater scientific impact is realized by the ability of the AMISR systems to operate unattended and for some systems on a 24/7 basis. The AMISR facility is remotely accessible, and the ISR and ancillary instruments have been designed to produce processed data that can 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 the students and student advisors from a number of universities to assist with training, experiment planning, and scheduling. The team will also maintain a repository for contributed course materials, technical data, and facility instrument information.

调查人员将操作和管理扑克平台和决心湾高级模块化非相干散射雷达(AMICR)设施。这一努力延续了过去五年来的设施运营和社区支持，重点是通过1.指导世界独特地区最先进设施的使用，2.提供与科学家和工程师团队的咨询和合作，3.为活动和长期测量计划提供后勤支持，4.提供对各种级别的处理和分析雷达数据的轻松访问，以及5.参与学生培训和协助学生导师。在很大程度上由于非相干散射雷达的使用，对地球上层大气、电离层和地球空间环境的认识在20世纪下半叶有了很大进步。然而，对最基本的过程的详细理解仍然有些含糊，因为这样的理解必须包括地球上层大气、电离层、磁层和太阳风的强耦合系统。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。与现有的ISR相比，阿米西里雷达具有显著的科学优势，这在很大程度上是由于相控阵天线提供的快速转向。这种脉冲对脉冲的转向能力可以被用来解决机械操纵碟基系统测量中固有的许多时间/空间模糊问题。相控阵系统能够对电离层结构进行短时间尺度的三维成像，并跟踪其演变。也许更大的科学影响是，阿米西里研究中心的系统能够在无人看管的情况下运行，并对某些系统全天候运行。阿米西里研究所的设施可以远程访问，ISR和辅助仪器的设计目的是产生经过处理的数据，这些数据可以公开提供，并通过互联网分发给用户群体。提供用户友好的数据和显示能力，以满足社区的研究需要，是阿米西里研究中心业务的重要组成部分。一个强大的、分散的和训练有素的用户社区的支持对阿米西里项目的整体科学成功非常重要。阿米西里管理团队将直接与来自多所大学的学生和学生导师合作，协助培训、实验计划和日程安排。该小组还将维护一个储存库，用于存储贡献的课程材料、技术数据和设施仪器信息。
