This award supports the operation and scientific use of the Super Dual Auroral Radar Network (SuperDARN). SuperDARN is a global network of HF radars that provide continuous measurements of the high-latitude ionosphere in both the northern (9 radars) and southern (6 radars) hemispheres. It provides the meso- and global-scale views of the structure and dynamics of ionospheric plasma convection and electric fields that are needed to study the processes that couple mass and energy from the solar wind into the magnetosphere-ionosphere-atmosphere system. Other valuable measurements from the radars include the velocity of the neutral winds near the mesopause, proxies for the projection of magnetospheric boundaries into the ionosphere, and the characteristics of small-scale ionization irregularities. SuperDARN is an international collaboration involving the funding agencies of ten countries. The U. S. responsibility includes the operation of the SuperDARN radars at Goose Bay, Labrador and Kapuskasing, Ontario, as well as the data processing and distribution for the entire SuperDARN network. The U.S. research community gains access to the entire dataset through association with SuperDARN researchers at the awardee institution, Johns Hopkins University Applied Physics Laboratory (JHU/APL). As the founding institution of SuperDARN, JHU/APL provides oversight and management for the entire collaboration. The JHU/APL team is responsible for the development and distribution of the core operating software for the SuperDARN radars and for much of the analysis software. JHU/APL is also responsible for assembling data from the northern and Australian radars for subsequent DVD production. The activities at JHU/APL in support of the SuperDARN facility include both community support and research functions. The wider community is supported in its use of SuperDARN data by a variety of means, including distribution from a dedicated web site and the personal involvement of JHU/APL staff. The research programs of the JHU/APL team include the response of ionospheric convection to IMF variations, the realization of a space weather capability for ionospheric electric fields, and the magnetic conjugacy of convection between the ionosphere and magnetosphere. Other topics to be studied include global determination of atmospheric Joule heating, characterization of planetary waves in the mesosphere, and collaborative research with the NSF Advanced Modular Incoherent Scatter Radar (AMISR). The planned construction of additional SuperDARN radars, which will both augment the existing high-latitude chains and extend coverage into the polar cap and mid-latitude regions, promises a significant boost in the supply of data for resolving critical problems in Sun-Earth connections research.

该奖项支持超级双极光雷达网络（SuperDarn）的操作和科学用途。 Superdarn是HF雷达的全球网络，可在北部（9雷达）和南部（6个雷达）半球中连续测量高纬度电离层。它提供了对电离层等离子体对流的结构和动力学的中尺度和全球尺度观点，这些观点和电场是研究将太阳能风中的质量和能量从太阳能风层融合到磁层 - 欧离子层 - 大气系统的过程中所需的。来自雷达的其他有价值的测量值包括中间风的速度，磁层边界投射到电离层中的代理以及小尺度电离不规则性的特征。 Superdarn是一项国际合作，涉及十个国家的资助机构。美国的责任包括在鹅湾，拉布拉多和卡普斯卡辛，安大略省的Superdarn Radars的操作，以及整个Superdarn网络的数据处理和分发。美国研究界通过与获奖者机构约翰·霍普金斯大学应用物理实验室（JHU/APL）的超级研究人员的关联来获得对整个数据集的访问。作为Superdarn的创始机构，JHU/APL为整个合作提供了监督和管理。 JHU/APL团队负责为SuperDarn Radars和大部分分析软件开发和分发核心操作软件。 JHU/APL还负责从北部和澳大利亚雷达的数据组装数据，以进行随后的DVD生产。 JHU/APL的活动以支持Superdarn设施，包括社区支持和研究功能。通过各种手段使用SuperDarn数据，包括从专门的网站分发以及JHU/APL员工的个人参与，支持了更广泛的社区。 JHU/APL团队的研究计划包括电离层对流对IMF变化的反应，实现电离层电场的太空天气能力以及电离层和磁层之间对流的磁性结合。要研究的其他主题包括全球确定大气焦耳加热，中层的行星波的表征以及与NSF高级模块化不相互不相互分散射雷达（AMISR）的协作研究。计划的额外超级雷达的构建将增加现有的高纬度链，并将覆盖范围扩展到极性盖和中纬度区域，这有望大大提高在Sun-Earth Connections研究中解决关键问题的数据供应。
