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.

先进模块化非相干散射雷达（AMISR）设施，包括扑克牌平面非相干散射雷达（PFISR），阿拉斯加的相关光学仪器，Resolute Bay天文台（RBO）和Resolute Bay非相干散射雷达北脸（RISR-N），是国家科学基金会（NSF）的研究和教育设施，为大气和地球空间科学的广泛研究人员提供服务。这些非相干散射雷达（ISR）用于检查地球大气层的电磁带电层的特性。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跨极航空的影响。除了维护基础设施，使研究和教育，学生参与AMISR研究的支持，优先考虑学生实验，参加社区研讨会，通过SRI研究经验本科生计划招募本科生，在UAF招募本科生，以协助光学数据分析，并参加年度ISR暑期学校。该项目包括继续在现有地点运营和维护这些设施，不新建或大修。AMISR设施提供独特的观测能力，继续使各种科学调查有关的多个太阳和空间物理十年调查目标的太阳风磁层和大气层-电离层-磁层的相互作用。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。这一位于极冠深处的位置允许对极地地球空间环境进行独特的调查。PFISR的先进雷达能力、阿拉斯加广泛的光学仪器套件、扑克平原研究靶场（PFRR）的探空火箭发射能力以及PFRR位于主要极光椭圆区的位置相结合，使PFRR成为世界上高层大气物理学、极光等离子体物理学和磁层-电离层耦合研究的首要地点之一。AMISR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档，以支持未来的科学调查。SRI国际（SRI），阿拉斯加大学费尔班克斯（UAF）和ATCO结构和物流（ATCO）将共同管理这个项目。操作和维护计划包括管理用户要求的每台雷达的实验，在PFISR连续低占空比操作的持续操作，数据的例行分析和分发，现有硬件的维护，以及对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NSF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。
