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.

了解高层大气的变化非常重要，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，从而能够研究大气的变化、高能电子分布、以及高频无线电波传播将如何受到影响。国家研究委员会强调了电离层修改技术（人工加热）对于主流航空学研究的潜力。在全国兴趣”还强调了 HAARP 设施的战略和技术意义，并主张扩大研究生和本科生参与该项目的力度。每年都会举办一次暑期学校和一次专题研讨会。事实证明，过去的研究在招生和保留学生方面表现出色。该项目将在阿拉斯加的 HAARP 设施中使用电离层修改方法来研究四个科学主题：1）中性大气的昼夜变化，2）高能电子分布和控制因素，3）上层混合波的探测，以及4）通过实验和理论研究计划的高频无线电波传播和闪烁，这项工作将使用新的实验模式来测量难以测量的中性风。该团队将部署和操作多种诊断仪器来检测其影响，并在 HAARP 进行加热活动。该诊断仪器将提供给其他 HAARP 研究人员以提高科学影响力。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
