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坦和坚决的湾高级模块化散射雷达（AMISR）设施。这项努力延续了过去五年来的设施运营和社区的支持，重点是通过1。指导在世界独特地区使用最先进的设施，2。向科学家和工程师提供咨询与协作的员工，3。提供物流支持，以提供各种访问和长期的培训，以访问各个级别的学生，并为各种级别提供了范围，并在各个级别上访问了各种级别的数据，并为各种级别的数据提供了范围，并分析了范围，并分析了范围，并分析了范围，并提供了范围。学生顾问。在二十世纪下半叶，在很大程度上，由于使用不连贯的散射雷达（ISRS），对地球上层大气层，电离层和地球上环境的了解已显着发展。然而，对即使是最基本的过程的详细理解仍然有些模糊，因为这样的理解必须涵盖地球上层大气，电离层，磁层和太阳风的强烈耦合系统。有时，重要的时间尺度的范围从秒到几天。同样，相关的空间尺度范围从子计量器到数千公里。与现有ISR相比，AMISR雷达具有显着的科学优势，这在很大程度上是由于分阶段阵列天线提供的快速转向。可以利用这种脉冲到脉冲转向能力来解决基于机械转向盘式系统的测量中固有的许多时间/空间歧义。一个分阶段的阵列系统可以使电离层结构的短时间，三维成像以及其进化的跟踪。也许通过AMISR系统在24/7的基础上运行无人值守的能力和某些系统的能力来实现更大的科学影响。 AMISR设施可远程访问，ISR和辅助工具旨在生成可以公开提供并通过Internet向用户社区分发的处理数据。满足社区研究需求的用户友好数据和显示功能的提供是AMISR操作的重要组成部分。对强大，分布和训练的用户社区的支持对于AMISR项目的整体科学成功非常重要。 AMISR管理团队将直接与许多大学的学生和学生顾问合作，以协助培训，实验计划和日程安排。该团队还将维护一个存储库，以供课程材料，技术数据和设施工具信息。
