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.

该合同将支持拉布拉多古斯湾大气雷达设施的运营和维护。 该雷达是位于北部和南部高纬度地区的名为 SuperDARN 的全球雷达网络中的第一个。 雷达对电离层电子密度不规则性的反向散射很敏感。 他们的主要数据产品是不规则体的漂移速度以及产生漂移的电场的大小和方向。 SuperDARN是唯一能够对高纬度电场进行连续、大规模、直接观测的实验技术。 SuperDARN 网络是与来自十个国家的科学家合作的成果，该奖项支持 SuperDARN 社区内的一些协调工作，包括准备来自北半球站点的数据磁带以及将这些磁带分发给研究界。 研究人员还将在两个领域进行科学研究：1）高纬度对流的全球尺度结构和动力学；2）大气和电离层对高纬度电场的响应。 了解电离层电场的整体结构和动态行为对于理解近地空间环境的过程以及确定电磁能量输入到地球高层大气高纬度区域的重要性至关重要。
