Advanced Modular Incoherent Scatter Radar (AMISR) Operations and Maintenance

先进的模块化非相干散射雷达（AMISR）设施，包括Poker平面非相干散射雷达（PFISR）、阿拉斯加的相关光学仪器、Resolute湾天文台（RBO）和Resolute湾非相干散射雷达北面（RISR-N），是美国国家科学基金会（NSF）的研究和教育设施，为大气和地球空间科学领域的广泛研究人员提供服务。这些非相干散射雷达（ISRs）被用来检测地球大气层中电磁带电层的特性。AMISR科学与空间天气的几个社会重要方面直接相关，包括地磁感应电流、卫星阻力、无线电闪烁、无线电吸收、辐射带粒子环境和空间天气对超极航空的影响。除了维护能够进行研究和教育的基础设施外，学生参与AMISR研究的支持还包括优先考虑学生实验，参加社区研讨会，通过SRI本科生研究经验计划招募本科生，在UAF招募本科生协助光学数据分析，以及参加年度ISR暑期学校。该项目包括在现有地点继续运营和维修这些设施，不新建或进行重大维修。AMISR设施提供了独特的观测能力，继续为太阳风-磁层和大气-电离层-磁层相互作用的多个太阳和空间物理年代际调查目标提供各种科学调查。RBO是世界上唯一一个在地磁纬度80度以上的非相干散射雷达站点。这个位于极帽深处的位置允许对极地地球空间环境进行独特的调查。PFRR的先进雷达能力，阿拉斯加广泛的光学仪器套件，扑克平坦研究范围（PFRR）的探空火箭发射能力，以及PFRR在主要极光椭圆中的位置，使PFRR成为世界上研究高层大气物理，极光等离子体物理和磁层-电离层耦合的首选地点之一。AMISR的运营和维护团队将通过各种社区参与活动积极支持用户驱动的科学。此外，SRI团队将开发新的数据产品和文件，以支持未来的科学调查。SRI国际公司（SRI）、阿拉斯加费尔班克斯大学（UAF）和ATCO结构与物流公司（ATCO）将共同管理该项目。操作和维护计划包括管理用户要求的每台雷达的实验，PFISR持续低占空比操作的持续运行，数据的常规分析和分发，现有硬件的维护以及RBO所有其他仪器的后勤支持。此外，还进行了几项工程研究，以制定设施的长期维护计划。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The Advanced Modular Incoherent Scatter Radar (AMISR) facilities, including the Poker Flat Incoherent Scatter Radar (PFISR), the associated optical instrumentation in Alaska, the Resolute Bay Observatory (RBO), and the Resolute Bay Incoherent Scatter Radar North Face (RISR-N), are National Science Foundation (NSF) Research and Educational Facilities that serve a broad community of researchers in atmospheric and geospace science. These incoherent scatter radars (ISRs) are used to examine the properties of the electromagnetically charged layers of Earth's atmosphere. AMISR science is directly relevant to several societally important aspects of space weather, including geomagnetically induced currents, satellite drag, radio scintillation, radio absorption, the radiation belt particle environment, and space weather impacts on transpolar aviation. In addition to maintaining infrastructure that enables research and education, student involvement in AMISR research is supported by prioritizing student experiments, attending community workshops, recruiting undergraduates through the SRI Research Experience for Undergraduates program, recruiting undergraduates at UAF to assist with optical data analysis, and participating in the annual ISR summer school. The project includes the continued operation and maintenance of these facilities at their current locations with no new construction or major repairs. The AMISR facilities offer unique observational capabilities that continue to enable a variety of scientific investigations related to multiple Solar and Space Physics Decadal Survey goals for Solar Wind-Magnetosphere and Atmosphere- Ionosphere-Magnetosphere interactions. RBO is the only incoherent scatter radar site in the world above 80 degree geomagnetic latitude. This location deep in the polar cap permits unique investigations of the polar geospace environment. The combination of the advanced radar capabilities of PFISR, the extensive suite of optical instruments in Alaska, the sounding rocket launch capabilities at the Poker Flat Research Range (PFRR), and the location of PFRR in the main auroral oval make PFRR one of the premiere sites in the world for research in upper atmospheric physics, auroral plasma physics, and magnetosphere- ionosphere coupling. The AMISR operations and maintenance team will proactively support user-driven science through a variety of community engagement activities. Furthermore, the SRI team will develop new data products and documentation to enable future science investigations. SRI International (SRI), the University of Alaska Fairbanks (UAF), and ATCO Structures and Logistics (ATCO) will jointly manage this project. The operation and maintenance plan includes managing user-requested experiments for each radar, continued operation of continuous low duty cycle operations at PFISR, routine analysis and distribution of data, maintenance of existing hardware, and logistical support for all other instruments at RBO. Additionally, several engineering studies to formulate long-term maintenance plans for the facilities.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
