This is a five year Faculty Early Career Development project to carry out integrated research and education activities under the theme of inter-hemispheric space weather connections. An overarching science objective for the research efforts to be undertaken is the investigation of the inter-hemispheric magnetic conjugacy of ionospheric irregularities and convection on closed magnetic field lines. This will be done based mainly on simultaneous measurements from the NSF-supported SuperDARN network of radars in the northern and southern hemispheres. Statistical and case study analysis of more than 20 years of existing SuperDARN radar data from northern and southern hemisphere sites in the auroral and mid-latitude regions will be conducted. A particular emphasis will be to compare the degree of conjugacy between the auroral zone and the subauroral ionosphere. The recent expansion of SuperDARN to middle latitudes provides new capabilities to investigate inter-hemispheric conjugacy in the subauroral ionosphere, including a unique 20 month-long dataset of combined measurements from the Falkland Islands and Wallops radars. The research effort will form the basis for a graduate degree as well as various self-contained research projects for undergraduate students. Significant additional education and outreach activities in the project are designed to enhance the exposure of students to space science research and associated engineering in undergraduate education and pre-college summer camps at Virginia Tech. The central concept of inter-hemispheric space weather connections will be integrated into the undergraduate curriculum and summer camp activities. Pre-college and undergraduate students will use newly purchased hand-held radio receiver equipment to search for natural VLF signals (such as sferics, tweeks and whistlers) and learn about inter-hemispheric space weather phenomena. Undergraduate students will be employed as teaching assistants for the summer camp activities. The acquisition of a research grade ELF/VLF receiver will broaden the radio science activities at Virginia Tech and operation of the instrument will become a student-led research effort. The project will provide full tuition and stipend support for a graduate student to pursue Ph.D. research on inter-hemispheric conjugacy of ionospheric convection. Travel funds will be provided for the graduate student to attend yearly scientific meetings in the US, and to visit twice with SuperDARN partner organizations in the UK for extensive collaboration. All education and outreach components include appropriate and significant measures of evaluation and assessment that will be conducted in collaboration with the Office of Academic Assessment at Virginia Tech.

这是一个为期五年的教师早期职业发展项目，目的是在半球间空间气象联系的主题下开展综合研究和教育活动。 将要开展的研究工作的一个首要科学目标是调查封闭磁力线上电离层不规则性和对流的半球间磁共轭。 这将主要基于NSF支持的SuperDARN雷达网络在北方和南半球的同步测量。将对来自极光区和中纬度地区北方和南半球站点的20多年来现有SuperDARN雷达数据进行统计和案例研究分析。将特别强调比较极光区和极光下电离层之间的共轭程度。SuperDARN最近扩展到中纬度地区，提供了调查极光下电离层半球间共轭的新能力，包括福克兰群岛和Wallops雷达联合测量的独特的20个月数据集。 研究工作将形成研究生学位的基础，以及为本科生的各种独立的研究项目。该项目还开展了大量教育和宣传活动，目的是在弗吉尼亚理工大学的本科教育和大学预科夏令营中使学生更多地接触空间科学研究和相关工程。 将把半球间空间气象联系的中心概念纳入本科课程和夏令营活动。大学预科生和本科生将使用新购买的手持无线电接收机设备搜索自然甚低频信号（如天电、高音和哨声），并了解半球间空间天气现象。本科生将被聘为夏令营活动的助教。研究级ELF/VLF接收器的获得将扩大弗吉尼亚理工大学的无线电科学活动，仪器的操作将成为学生主导的研究工作。该项目将为攻读博士学位的研究生提供全额学费和助学金支持。电离层对流的半球间共轭性研究。将为研究生提供旅行资金，以参加在美国举行的年度科学会议，并与英国的SuperDARN合作伙伴组织进行两次广泛的合作。 所有的教育和推广部分包括适当和重要的评价和评估措施，将与弗吉尼亚理工大学学术评估办公室合作进行。
