This RAPID would support ionosphere radio modification experiments at the Alaska High-frequency Active Auroral Research Program (HAARP) Observatory during its first university-run campaign, planned for February 2017. The application of the research specifically is to study with high temporal resolution the evolution of the white-light morphology of the artificial radio-induced aurora. Ownership of the HAARP facility was transferred from the US Air Force to the University of Alaska Fairbanks (UAF) in August, 2015. During campaigns, significant expenditures for fuel and personnel are required. Large start-up costs make HAARP experiments largely inaccessible to individual researchers unless multiple experiments and funding sources can be bundled together during a campaign of up to two-week duration. Based on recent pledged support from sponsors, UAF plans to conduct a limited experiment campaign in February 2017; this schedule is unflexible and consequently, the RAPID management of the award would enable the schedule to be enhanced with additional experiments thus utilizing the HAARP facility more effectively. Broader impacts will be maximized by encouraging public participation in various roles.This project is a singular opportunity for researchers to conduct ionosphere modification experiments by taking advantage of efficiencies gained through bundling onto the campaign already planned for February. The primary experimental objective of this project is to measure time-dependent artificial airglow or "aurora" morphology with a sensitive white-light video camera capable of 30 frames per second temporal resolution. The secondary experimental objective is to test Arctic HF radio propagation paths using community and amateur radio (ham) participation. Both experiment objectives are highly relevant to active areas of space physics and Arctic radio communications research. Ionosphere radio modification is an important experimental technique for investigating: 1) plasma processes difficult or impossible to replicate in a laboratory, 2) the near-earth space environment, 3) radio propagation properties, and 4) natural processes such as aurora that transfer energy into the upper atmosphere. The primary and secondary objectives are 1) to measure the white-light artificial aurora morphology with high temporal resolution and 2) to test possible HF radio propagation paths in the Arctic. Both experiment objectives align with formerly active areas of research at HAARP prior to the suspension of operations.

该RAPID将在阿拉斯加高频主动极光研究计划（HAARP）天文台的第一次大学运行活动期间支持电离层无线电修改实验，计划于2017年2月进行。该研究的应用具体是以高时间分辨率研究人工辐射诱导极光的白光形态的演变。HAARP设施的所有权于2015年8月从美国空军转移到阿拉斯加大学费尔班克斯（UAF）。在竞选期间，需要大量的燃料和人员开支。大量的启动成本使得HAARP实验在很大程度上无法为个人研究人员所用，除非多个实验和资金来源可以在长达两周的活动中捆绑在一起。根据赞助商最近承诺的支持，UAF计划在2017年2月进行有限的实验活动;该时间表不灵活，因此，对该奖项的快速管理将使时间表能够通过额外的实验得到加强，从而更有效地利用HAARP设施。通过鼓励公众以各种角色参与，将最大限度地扩大更广泛的影响。该项目为研究人员提供了一个独特的机会，通过利用捆绑到已计划于2月开展的活动中所获得的效率，进行电离层修改实验。该项目的主要实验目标是用一台灵敏的白光摄像机测量与时间有关的人造气辉或“极光”形态，该摄像机的时间分辨率为每秒30帧。第二个实验目标是使用社区和业余无线电（火腿）参与测试北极高频无线电传播路径。这两个实验目标都与空间物理学和北极无线电通信研究的活跃领域密切相关。电离层无线电修正是一项重要的实验技术，用于研究：1）在实验室中难以或不可能复制的等离子体过程，2）近地空间环境，3）无线电传播特性，以及4）将能量传递到高层大气的自然过程，如极光。主要和次要目标是：1）测量具有高时间分辨率的白光人造极光形态; 2）测试北极地区可能的高频无线电传播路径。这两个实验目标与HAARP在暂停运营之前的研究领域保持一致。
