The goal of this Mid-Size Infrastructure (MSI) project is to build a mid-latitude extension of the SuperDARN High Frequency (HF) radar network. Radars in the international SuperDARN network measure important properties of Earth's ionosphere, including electric fields, plasma structures, and acoustic gravity waves. Progress in the study of Earth's near-space environment increasingly relies on the availability of these critical measurements on global scales. The interest in SuperDARN data products has spurred the recent development of a pair of polar cap radars by Canadian colleagues, extending SuperDARN capabilities to the highest latitudes. This MSI project, which is a collaborative effort involving four institutions, will result in eight new radars distributed over four sites situated along an arc extending from the Azores through the central United States to the Aleutian Island chain. The new radars will provide unprecedented views of the dynamics of the subauroral ionosphere and inner magnetosphere. The feasibility of such measurements at middle latitudes has been demonstrated with the deployments of single, isolated SuperDARN radars in the eastern United States (Wallops Island, Blackstone) and in Japan (Hokkaido). The existing radars will be operationally folded into the MSI chain. The realization of this large-scale and long-term observational capability will furnish the space physics community with new infrastructure and a valuable tool for engaging students in cutting-edge research. SuperDARN data collected from high latitudes are used by space scientists all over the world. The existing radar network was developed incrementally over 15 years with the steady addition of international partners. This project will initiate the acquisition of comparable infrastructure at mid-latitudes thereby taking advantage of recent developments at polar latitudes and the existing high-latitude SuperDARN network to provide expanded coverage of effects in the magnetosphere, ionosphere, and neutral atmosphere. The protocols and distribution methods currently used for SuperDARN data and data products will be utilized to ensure the same ease of access to data. As occurred with high latitude SuperDARN, international partners are simultaneously seeking funds to build complementary radars in Europe and Asia. The participants in this project are all associated with institutions of higher learning and view the infrastructure as both a teaching and research investment. Data from the high-latitude SuperDARN radars have contributed to numerous advanced degrees and the mid-latitude extension will furnish many more opportunities. Students at the collaborating institutions will be heavily engaged in the work of this project both at their home institutions and at the individual radar sites. Measurements provided by the infrastructure will enable transformational science and support research across a broad range of topics in the physics of the magnetosphere, ionosphere, and upper atmosphere. At the same time, this effort will: (1) provide the research community with extensive mid-latitude ionospheric and atmospheric datasets; (2) provide large-scale context for ongoing and future spacecraft and rocket missions; (3) generate new research possibilities in space science for students; (4) provide opportunities for students at U.S. universities to gain hands-on experience with radar technology and in the management of a major scientific collaboration. All data and data products will be made freely available through the SuperDARN website.

这个中型基础架构（MSI）项目的目标是建立Superdarn高频（HF）雷达网络的中纬度扩展。 国际超级网络中的雷达测量地球电离层的重要特性，包括电场，等离子体结构和声性重力波。 对地球近距离环境的研究的进展越来越依赖于这些关键测量在全球尺度上的可用性。 对Superdarn数据产品的兴趣刺激了加拿大同事最近开发的一对极地帽雷达，将Superdarn能力扩展到了最高的纬度。 这个MSI项目是涉及四个机构的合作努力，将导致八个新的雷达在沿弧线延伸到美国中部到阿留申岛连锁店的四个地点分布。 新的雷达将提供前回离电离层和内部磁层动力学的前所未有的视图。 在美国东部（美国沃洛普斯岛，黑石石）和日本（北海道）部署中，在中纬度地区和日本（Hokkaido）的单个孤立的超级雷达的部署已经证明了这种测量值的可行性。 现有的雷达将在操作上折叠到MSI链中。 这种大规模和长期观察能力的实现将为太空物理社区提供新的基础设施，并为吸引学生参与尖端研究的有价值工具。 全世界的太空科学家都使用了从高纬度地区收集的超档数据。 现有的雷达网络在15年内逐渐开发，并稳定地增加了国际合作伙伴。 该项目将启动在纬度中部的可比基础设施的获取，从而利用极地纬度的最新发展和现有的高纬度超darn网络，以提供磁层，电离层和中立氛围的效果的扩展覆盖范围。 当前用于超级数据和数据产品的协议和分发方法将用于确保易于访问数据。 正如高纬度超级达人所发生的那样，国际合作伙伴正在寻求资金在欧洲和亚洲建立互补的雷达。 该项目的参与者都与高等教育机构有关，并将基础设施视为教学和研究投资。 来自高纬度超级雷达的数据促成了许多高级学位，中纬度扩展将为更多机会提供更多机会。 合作机构的学生将大量参与该项目的工作，无论是在他们的家庭机构还是在各个雷达站点。 基础设施提供的测量将使磁层，电离层和高层大气的物理学广泛主题的转化科学和支持研究。 同时，这项工作将：（1）为研究界提供广泛的中纬度电离层和大气数据集； （2）为正在进行的和未来的航天器和火箭任务提供大规模背景； （3）为学生提供空间科学的新研究可能性； （4）为美国大学的学生提供机会，以获得雷达技术的动手经验以及进行主要科学合作的管理。 所有数据和数据产品将通过SuperDarn网站免费提供。
