This award supports the operation and maintenance of the Kodiak, Alaska, SuperDARN radar and associated research using data from the network. SuperDARN is an international network of high frequency radars that measure the motion of ionized plasma in Earth's ionosphere. At high latitudes, the plasma motion is indicative of coupling processes between the solar wind, the magnetosphere, and the upper atmosphere. Operational tasks for the SuperDARN site at Kodiak include periodic maintenance visits to the site, software maintenance, development of control programs, updating the operating schedule, and monitoring the status of data transfers from the radar to the SuperDARN archive, maintenance of local computer systems to host the data, and support of users in the use and interpretation of the data. The research plan includes substorm studies, auroral electric fields, irregularity generation, neutral wind forcing by the ionospheric plasma, investigation of hemispheric conjugate phenomena, convection dynamics, and convection modeling. The study addresses some of the fundamental problems of space physics, and continued operation of the SuperDARN network advances understanding of the Earth's upper atmosphere, ionosphere, and magnetosphere, and the impact of solar disturbances on the Earth's plasma environment. Broader impacts include the maintenance of scientific infrastructure for the benefit of the scientific community. SuperDARN is widely used in the space physics and aeronomy community and each radar plays an essential role. Because it is an international network, SuperDARN fosters collaboration among member nations. There are currently at least ten nations that support SuperDARN work. It plays an important role in the space physics research programs in each of these nations. The cooperative scientific effort fostered under this program will also contribute to the education of the next generation of scientists.

该奖项支持阿拉斯加州科迪亚克SuperDARN雷达的运行和维护，以及使用网络数据进行相关研究。SuperDARN是一个国际高频雷达网络，用于测量地球电离层中电离等离子体的运动。 在高纬度地区，等离子体运动是太阳风、磁层和高层大气之间耦合过程的指示。 科迪亚克SuperDARN站点的业务任务包括定期对站点进行维护访问、软件维护、开发控制程序、更新运行时间表、监测从雷达到SuperDARN档案库的数据传输状况、维护存放数据的本地计算机系统以及支持用户使用和解释数据。研究计划包括亚暴研究、极光电场、不规则性生成、电离层等离子体对中性风的强迫、半球共轭现象的研究、对流动力学和对流建模。该研究涉及空间物理学的一些基本问题，SuperDARN网络的持续运行将增进对地球高层大气、电离层和磁层以及太阳扰动对地球等离子体环境的影响的了解。更广泛的影响包括维护科学基础设施，造福科学界。SuperDARN广泛用于空间物理和高空大气物理学领域，每一部雷达都发挥着至关重要的作用。由于它是一个国际网络，SuperDARN促进了成员国之间的合作。目前至少有10个国家支持SuperDARN的工作。它在这些国家的空间物理研究计划中发挥着重要作用。在该计划下促进的合作科学努力也将有助于下一代科学家的教育。
