SuperDARN Radar Investigations Global Scale

项目摘要

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.

该奖项将支持拉布拉多鹅湾的大气雷达设施的运营和维护。雷达是位于北部和南部高纬度地区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的反向散射敏感。他们的主要数据产品是不规则性的漂移速度以及产生漂移的电场的大小和方向。 Superdarn是唯一可以对高纬度电场进行连续，大规模直接观察的实验技术。 Superdarn网络是与十个国家的科学家合作的结果，该奖项支持Superdarn社区内的一些协调工作，包括从北半球站点准备的数据录像带以及将这些磁带分配给研究界的数据录像带。研究人员还将在两个领域进行科学研究：1）高纬度对流的全球规模结构和动力学以及2）大气和电离层对高纬度电场的反应。对电离层电场的全球结构和动态行为的了解对于理解近地太空环境中的过程以及确定电磁能输入对地球上层大气的高纬度区域的重要性至关重要。
