Collaborative Research: Combining Heating And Radio Diagnostics On Natural AeronomY (CHARDONAY)

这项研究将使用高频主动极光研究计划（HAARP）设施，利用高频辐射人为地干扰电离层。这种技术，被称为电离层修正，刺激电离层的反应，可以在没有伴随极光和高能太阳事件的电离层自然激发的“杂波”的情况下进行研究。拟议的努力将重新开放HAARP天文台，在其从阿拉斯加大学的军事管理过渡到民用管理之后。计划中的工作也与美国国家科学基金会资助的高纬度雷达网络的测量结果进行了很好的协调。因此，这一建议为建设基础设施提供了巨大的机会。HAARP设施举办了一个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的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、电导和极地中间层云物理等现象。这些过程都促进了能量从太阳风通过磁层、热层和电离层（MTI）向中性大气的转移。为了模拟和预测MTI系统对太阳爆炸事件的响应，以及这种所谓的？空间天气吗?关于通信和导航系统。

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.
