SuperDARN (Dual Auroral Radar Network)

为了获得高纬度电离层对流及其相关现象的全球覆盖范围，本文研究了一个扩展的高纬度高频雷达纵向链。这条链将提供高纬度等离子体对流的连续二维观测，在一个视野范围内，最终将延长长达14小时的磁地方时和不变纬度650到850度。超级雷达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；本提案将研究其中的第一对。该网络将为高纬度电离层对流格局的大尺度结构和动力演化及其对高层大气结构和动力学的影响的研究提供新的思路。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，以及高纬度源激发的引力波的大尺度分布和传播。

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.
