Collaborative Studies of the High Latitude Ionosphere Using a Dynasonde Network in the Scandinavian Sector

该建议打算利用部署在挪威北极地区的数字电离层探测器网络，研究高纬度电离层的物理学。这项研究将与来自英国和斯堪的纳维亚国家的欧洲研究人员合作进行，将利用从挪威北方到斯瓦尔巴特群岛的三个仪器的数据。动态测高仪将在非相干散射雷达的视场内，因此将受益于对小电离层体积的详细测量。这项研究的一个主要重点将是更多地了解白昼侧电离层尖点区域的物理学，在那里冲击太阳风到达电离层，并确定各种过程的电离层特征。垂直入射电离层探测测量将用于解决当代科学辩论的各种问题，如向阳面尖点的时间持续性，向阳面电离层瞬态特征的行为，以及大尺度密度增强的形态。犹他州州立大学和威尔士大学之间交换学生的教育机会是可行的，因为后者的一个方案。学生也可以通过挪威大学联合会最近设立的斯瓦尔巴特群岛北极研究方案参加。

Using a network of digital ionospheric sounders (dynasondes) deployed in the Norwegian Arctic, this proposal intends to study the physics of the high-latitude ionosphere. This study, which is to be conducted in collaboration with European researchers from the UK and Scandinavian countries, will utilize data from three instruments that span the region from Northern Norway to Svalbard. The dynasondes will be within the field of view of the incoherent scatter radars and hence will benefit from detailed measurements over small ionospheric volumes. A primary emphasis of this study will be to learn more about the physics of the dayside ionospheric cusp region, where shocked solar wind reaches the ionosphere, and to identify the ionospheric signature of various processes. Vertical incidence ionospheric sounding measurements will be employed to address various issues of contemporary scientific debate, such as the temporal persistence of the dayside cusp, the behavior of transient features in the dayside ionosphere, and the morphology of large scale density enhancements. An educational opportunity for the exchange of students between Utah State University and the University of Wales is feasible as the result of a program at the latter institution. Student participation is also possible through a recently established program of Arctic studies on Svalbard by a consortium of the Norwegian Universities.
