Aeronomy Research Using Ionospheric Modifications

项目摘要

Understanding the variability in the upper atmosphere is important because it will help us better understand the space weather effects in that region. The HAARP facility can generate artificial heating in the atmosphere to enable the study of the variability of the atmosphere, the energetic electron distribution, and how the HF radio wave propagation would be affected. The project will lead to discovery and advance our understanding of space weather effects. The National Research Council emphasized the potential of ionospheric modification techniques (artificial heating) for mainstream aeronomy research. The “Arctic Research in the National Interest” also highlighted the strategic and technological significance of HAARP facility and argued in favor of an expanded role in basic research. Graduate and undergraduate students will be involved in the project. There will be a summer school and a topical symposium annually. These activities in the past have proven to be excellent in student recruitment and retention. This project will use ionospheric modification methods at the HAARP facility in Alaska to investigate four scientific topics: 1) the diurnal and day-to-day variability of the neutral atmosphere, 2) the energetic electron distribution and controlling factors, 3) the detection of upper-hybrid waves, and 4) the HF radio wave propagation and scintillation through a program of experimental and theoretical research. Using novel experimental modalities, this work will measure neutral winds that are difficult to measure by other means, employ a novel method to infer the suprathermal electron distribution, and apply ionospheric modification for general space weather studies. The team will field and operate several diagnostic instruments to detect the effects and will run heating campaigns at HAARP semiannually. The diagnostic instruments will be available to other HAARP investigators for use to increase the scientific impact.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.

了解高层大气的变异性很重要，因为它将帮助我们更好地了解该地区的空间天气影响。 HAARP设施可以在大气中产生人工加热，以便研究大气的变异性，能量电子分布以及HF无线电波传播将如何影响。该项目将导致发现并提高我们对太空天气影响的理解。国家研究委员会强调了电离层修饰技术（人工加热）对主流航空研究的潜力。 “国家利益的北极研究”还强调了HAARP设施的战略和技术意义，并主张支持在基础研究中发挥不断扩大的作用。研究生和本科生将参与该项目。每年将有一所暑期学校和局部研讨会。过去，这些活动在学生招募和保留方面非常出色。 This project will use ionosphere modification methods at the HAARP facility in Alaska to investigate four scientific topics: 1) the diurnal and day-to-day variability of the neutral atmosphere, 2) the energetic electronic distribution and controlling factors, 3) the detection of upper-hybrid waves, and 4) the HF radio wave propagation and scintillation through a program of experimental and theoretical research.使用新颖的实验方式，这项工作将测量难以通过其他方式衡量的中性风，员工一种新的方法来推断超颗粒电子分布，并将电离层修改应用于一般太空天气研究。该团队将进行范围并操作几种诊断工具来检测效果，并在半年度HAARP进行供暖活动。该诊断工具将用于其他HAARP调查人员，以增加科学影响。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，通过评估来诚实地获得支持。
