This award focuses on a specific research program that will be using data from the neutron monitor at McMurdo (which will be then moved to Jang Bogo) and from other worldwide locations. The research program is based on a unique southward cosmic rays "viewing direction" of the subject monitor for comprehensive analyses of individual solar events by measuring three dimensional distribution functions of solar energetic particles. The long and complete database acquired by the McMurdo monitor over 50+ years also plays an important role in the studies of historical trends in "solar modulation" of galactic cosmic rays and the influence of solar magnetic activity on the radiation input into the Earth's atmosphere. The recent deep solar minimum and slow recovery to the maximum are unprecedented for the potentially new era in the studies of the Sun. To ensure continuity of the McMurdo long-term dataset, it is proposed to move the monitor to the new Korean station Jang Bogo, which is located in Terra Nova Bay and has the viewing direction nearly identical to that of McMurdo. Solid science, international partners, and travel to Antarctica provide an ideal opportunity to achieve excellent education and outreach goals. By providing undergraduates and two-year college students with Antarctic research experience, the proposal demonstrates how a future generation of scientists can make meaningful contributions to the cutting-edge research.

该奖项的重点是一个具体的研究项目，该项目将使用麦克默多(随后将被转移到Jang Bogo)的中子监测器和来自世界各地的数据。该研究计划是基于主题监视器独特的向南宇宙射线“观察方向”，通过测量太阳高能粒子的三维分布函数，对单个太阳事件进行综合分析。麦克默多监测器50多年来获得的长期而完整的数据库，在研究银河系宇宙射线“太阳调制”的历史趋势以及太阳磁活动对输入到地球大气层的辐射的影响方面也发挥了重要作用。对于太阳研究中潜在的新时代来说，最近的太阳深度极小和缓慢恢复到最大值是前所未有的。为了确保麦克默多长期数据集的连续性，建议将监视器移到新的韩国站Jang Bogo，该站位于Terra Nova Bay，其观测方向与McMurdo几乎相同。扎实的科学、国际合作伙伴和南极洲旅行为实现卓越的教育和外展目标提供了理想的机会。通过为本科生和两年制大学生提供南极研究经验，该提案展示了未来一代科学家如何为尖端研究做出有意义的贡献。
