SuperDARN (Dual Auroral Radar Network)

这项提议调查扩展的高纬度高频雷达纵向链，以获得对高纬度电离层对流和相关现象的全球范围的复盖。这一链将在一个视场内提供高纬度等离子体对流的连续二维观测，最终将在当地时间14小时和恒定纬度65o至85o范围内延伸。SuperDARN网络由四对雷达组成，分布在从阿拉斯加到芬兰的五个地点；这项提案将研究第一对雷达。该网络将为研究高纬度电离层对流模式的大尺度结构和动力学演化及其对高层大气结构和动力学的影响提供洞察力。此外，该网络将有助于研究高纬度电离层不规则性的全球分布和传输，以及由高纬度源激发的大尺度分布和传播重力波。

This proposal investigates an extended longitudinal chain of high-latitude HF radars in order to obtain global-scale coverage of high-latitude ionospheric convection and related phenomena. This chain will provide continuous, two-dimensional observations of high-latitude plasma convection within a field of view that will eventually extend over as much as 14 hours of magnetic local time and 65o to 85o in invariant latitude. The SuperDARN network consists of four pairs of radars sited at five locations extending from Alaska to Finland; this proposal will study the first of these pairs. This network will provide insight to studies in large-scale structure and dynamical evolution of the high-latitude ionospheric convection pattern and its effects on the structure and dynamics of the upper atmosphere. Further, the network will aid in studying global distribution and transport of high latitude ionospheric irregularities as well as the large-scale distribution and propagation gravity waves excited by high-latitude sources.
