SuperDARN Radar Investigations of Global Scale Processes in the High-Latitude Ionosphere: Science and Infrastructure Support

该合同将支持位于拉布拉多Goose Bay的大气雷达设施的运行和维护。该雷达是位于北部和南部高纬度地区的超级雷达全球网络中的第一个。雷达对电离层电子密度不规则的后向散射很敏感。他们的主要数据产品是不规则的漂移速度和产生漂移的电场的大小和方向。superdam是唯一能够提供连续、大规模、直接观测高纬度电场的实验技术。superdamn网络是与来自10个国家的科学家合作的结果，该奖项支持superdamn社区内部的一些协调工作，包括从北半球站点准备数据磁带并将这些磁带分发给研究社区。研究方向包括：高纬度对流的全球尺度结构与动力学；高纬度电场对大气和电离层的响应。了解电离层电场的整体结构和动态行为是理解近地空间环境过程和确定地球高层大气高纬度地区电磁能量输入重要性的基础。

This award will support the operation and maintenance of an atmospheric radar facility in Goose Bay, Labrador. The radar was the first of a worldwide network of radars called SuperDARN located in northern and southern high latitude regions. The radars are sensitive to backscatter from ionospheric electron density irregularities. Their primary data products are the drift velocity of the irregularities and the magnitude and direction of the electric field producing the drift. SuperDARN is the only experimental technique that can provide continuous, large-scale, direct observations of the high latitude electric field. The SuperDARN network is the result of a collaboration with scientists from ten countries and this award supports some of the coordination effort within the SuperDARN community, including the preparation of data tapes from the northern hemisphere sites and the distribution of those tapes to the research community. The investigators will also conduct scientific research in two areas: 1) Global-scale structure and dynamics of high-latitude convection and 2) Atmospheric and ionospheric responses to high-latitude electric fields. Knowledge of the global structure and dynamic behavior of ionospheric electric fields is fundamental to understanding processes in the near-Earth space environment and in determining the importance of electromagnetic energy input to the high-latitude regions of Earth's upper atmosphere.
