The research will use the High-frequency Active Auroral Research Program (HAARP) facilities to artificially perturb the ionosphere using high-frequency radiation. This technique, known as ionospheric modification, stimulates responses in the ionosphere that can be investigated in the absence of the "clutter" accompanying natural excitation of the ionosphere by aurorae and high-energy solar events. The proposed efforts would re-open the HAARP observatory following its transition from military to civilian management at the University of Alaska. The planned work is also very well coordinated with measurements from an NSF-funded network of high-latitude radars. This proposal therefore represents a substantial opportunity to build infrastructure. The HAARP facility hosts an atmospheric radiation and radio science summer school, and so has the potential to draw in new graduate students.The ionospheric modification technique allows properties such as temperature and density to be measured under highly controlled conditions. This information will used to study phenomena such as turbulence, diffusion, conductance, and polar mesosphere cloud physics. These processes all facilitate the transfer of energy from the solar wind through the magnetosphere, thermosphere and ionosphere (MTI) to the neutral atmosphere. Further understanding of this coupling is required in order to model and predict the response of the MTI system to explosive solar events, and the impact of this so-called ?space weather? on communication and navigation systems.

这项研究将使用高频有源极光研究计划(HAARP)设施，利用高频辐射人为扰乱电离层。这种技术被称为电离层修正，它刺激电离层中的反应，在没有极光和高能太阳事件自然激发电离层的“杂波”的情况下可以研究这种反应。拟议的努力将在阿拉斯加大学的HAARP天文台从军事管理过渡到文职管理之后重新开放。计划中的工作与NSF资助的高纬度雷达网络的测量也得到了很好的协调。因此，这项提议代表着建设基础设施的重大机会。HAARP设施举办了大气辐射和无线电科学暑期学校，因此有可能吸引新的研究生。电离层修改技术允许在高度可控的条件下测量温度和密度等特性。这些信息将用于研究湍流、扩散、电导和极地中间层云物理等现象。这些过程都有助于将能量从太阳风通过磁层、热层和电离层转移到中性大气。为了模拟和预测MTI系统对太阳爆发事件的反应，以及这种所谓的空间天气的影响，需要进一步了解这种耦合。在通信和导航系统方面。
