This is a collaborative research award involving the University of Texas at Dallas and Johns Hopkins University Applied Physics Laboratory. The investigators will use data from the SuperDARN radar network and the Defense Meteorological Satellite Program (DMSP) to study convection in the high latitude ionosphere. Both the SuperDARN radars and the DMSP spacecraft make routine measurements of ionospheric plasma motion, but both suffer from temporal and spatial limitations in their coverage. The study will begin with the calibration and validation of the two data sets, leading to the development of techniques to reconcile the observations. Once that is complete, combined data sets will be used to study the ionospheric response to changes in the interplanetary magnetic field (IMF). Specific questions to be addressed are the saturation of the cross polar cap potential when the IMF is southward, the response time of the convection to changes in the IMF, and convection patterns when the IMF is strongly northward. This work will aid in the development of space weather models which are used to predict conditions in the space environment that affect technological systems, such as electric power, navigation, and communication.

这是涉及得克萨斯大学达拉斯大学和约翰·霍普金斯大学应用物理实验室的合作研究奖。 研究人员将使用超级雷达网络和国防气象卫星计划（DMSP）的数据来研究高纬度电离层的对流。 SuperDarn雷达和DMSP航天器都可以常规测量电离层等离子体运动，但覆盖范围中都有时间和空间限制。 该研究将从两个数据集的校准和验证开始，从而导致技术和调解观测的技术。 一旦完成，将使用组合的数据集来研究对星际磁场（IMF）变化的电离层响应。 要解决的具体问题是IMF向南时交叉极盖电位的饱和度，对流对IMF变化的响应时间以及IMF向北强时的对流模式。 这项工作将有助于开发太空天气模型，这些模型用于预测影响技术系统（例如电力，导航和通信）的空间环境中的条件。
