High Latitude Ionospheric Plasma Dynamics

这笔赠款为约翰霍普金斯应用物理实验室和英国南极调查局(BAS)之间的合作提供了NSF支持，以在BAS的哈雷湾站操作高频相干散射雷达。该雷达是一对类似雷达的南部组件，而北部组件位于鹅湾拉布拉多，与哈雷湾位于同一地磁线上。这样的一对被称为“磁性共轭”。该阵列被称为PACE(极地英美共轭实验)。此外，哈雷湾雷达的视场包括仪器齐全的USAP南极站上方的电离层。雷达可以一起绘制出两个半球极帽中电离层等离子体的密度和速度，为研究共轭现象和地球高纬度电离层如何对太阳风的变化做出反应提供了前所未有的机会。该项目是对国际日地物理(ISTP)、全球地球空间模型(GEM)和大气区域耦合、能量和动力学(CEDAR)计划的重要贡献。

This grant provides the NSF support for a collaboration between Johns Hopkins Applied Physics Laboratory and British Antarctic Survey (BAS) to operate a High Frequency coherent scatter radar at BAS's Halley Bay Station. The radar is the southern component of a pair of similar radars while the northern component is at Goose Bay Labrador, which is located on the same geomagnetic field line as Halley Bay. Such a pair is said to be "magnetically conjugate". The array is called PACE (Polar Anglo-American Conjugate Experiment). In addition, the Halley Bay radar has a field of view which includes the ionosphere above the well instrumented USAP South Pole Station. Together the radars can map the density and velocity of the ionospheric plasma in the polar caps of both hemispheres, providing unprecedented opportunities to study conjugate phenomena and how the Earth's high latitude ionosphere responds to changes in the solar wind. This project is an important contribution to the International Solar Terrestrial Physics (ISTP), Global Geospace Modelling (GEM) and Coupling, Energetics and Dynamics through Atmospheric Regions (CEDAR) programs.//
