Advanced Modular Incoherent Scatter Radar (AMISR) Operations and Maintenance: Looking Forward to a More Active Sun

调查人员将操作和管理Poker Flat和Resolute Bay先进模块化非相干散射雷达（AMISR）设施。这项工作延续了过去五年的设施运营和社区支持，重点是在2020年前协助研究界。1 .在世界独特地区指导使用最先进的设施；2 .为科学家和工程师提供咨询和合作的机会；为活动和长期测量项目提供后勤支持；提供方便地访问各种级别的处理和分析雷达数据；参与学生培训，协助学生辅导员。在20世纪下半叶，由于非相干散射雷达（ISRs）的使用，对地球上层大气、电离层和地球空间环境的认识有了显著的进步。然而，即使是对最基本过程的详细了解也有些模糊，因为这样的了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秒到天不等。同样，相关的空间尺度从亚米到数千公里不等。与现有isr相比，AMISR雷达具有显著的科学优势，主要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用来解决许多固有的时间/空间的模糊性测量从机械导向碟式系统。相控阵系统实现了电离层结构的短时间尺度三维成像和演化跟踪。也许更大的科学影响是通过AMISR系统无人值守和某些系统24/7全天候运行的能力实现的。AMISR设施可以远程访问，ISR和辅助仪器的设计目的是产生可公开获得的处理过的数据，并通过互联网分发给用户社区。提供用户友好的数据和显示能力，以满足社区的研究需要，是该系统业务的一个重要组成部分。强大的、分布式的、训练有素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管理团队将直接与来自多所大学的学生和学生顾问合作，协助培训、实验计划和安排。该小组还将维护一个存储库，用于提供课程材料、技术数据和设备仪器信息。

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.
