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.

该研究将使用高频主动的极光研究计划（HAARP）设施，使用高频辐射人为地扰动电离层。该技术被称为电离层修饰，刺激了电离层中的反应，在没有Aurorae和高能太阳能事件的“混乱”伴随着自然激发的情况下，可以研究这种反应。拟议的努力将在阿拉斯加大学从军事管理到平民管理过渡后重新开放HAARP天文台。计划的工作也很好地协调了NSF资助的高纬度雷达网络的测量。因此，该提案代表了建立基础设施的大量机会。 HAARP设施拥有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。电离层修饰技术允许在高度控制条件下测量温度和密度等特性。这些信息将用于研究诸如湍流，扩散，电导和极地层云物理等现象。这些过程都促进了能量从太阳风中通过磁层，热层和电离层（MTI）转移到中性气氛。需要进一步了解这种耦合，以模拟和预测MTI系统对爆炸太阳事件的响应以及所谓的“太空天气”的影响？关于通信和导航系统。
