This grant provides fund for the U.S. portion of a collaboration between Johns Hopkins University Applied Physics Laboratory (JHU/APL), British Antarctic Survey (BAS) and the South African National Antarctic Programme to build and operate an over-the- horizon high frequency (HF) auroral radar at the new South African station, Sanae. The project is known as the Southern Hemisphere Auroral Radar Experiment (SHARE). SHARE is essentially identical with the existing Polar Anglo-American Conjugate Experiment (PACE) radar at the BAS station at Halley Bay, Antarctica. When operated together, SHARE and PACE will provide 2-D mapping of plasma flow within their very large overlapping fields of view. Fortunately, they overlap above the U.S. South Pole station as well as much of the area to be instrumented with the new Automatic Geophysical Observatories (AGO's) and, therefore, can provide valuable additional information on the large-scale plasma flows above the observatories. These radars will also complement similar facilities in the Northern Hemisphere and will help to show how the aurora are sometimes the same and sometimes different in these magnetically connected regions. JHU/APL is the world leader in over-the-horizon HF auroral radar.

这笔赠款为合作的美国部分提供资金 约翰霍普金斯大学应用物理实验室 (JHU/APL）、英国南极调查局（BAS）和南非 国家南极计划将建立和运营一个过度的 新南非地平线高频极光雷达 车站，早苗。 该项目被称为南半球 极光雷达实验（SHARE）。 SHARE基本相同 与现有的极地英美共轭实验（PACE） 雷达在巴斯站在哈雷湾，南极洲。 操作时 SHARE和PACE将共同提供等离子体流的二维绘图 在它们非常大的重叠视野内。 幸运的是， 它们在美国南极站上方重叠， 该地区将配备新的自动地球物理 观测站（AGO），因此，可以提供有价值的 关于大规模等离子体流动的额外信息 天文台。 这些雷达还将补充 这将有助于展示极光是如何 有时相同，有时不同， 连接的区域。 JHU/APL是世界领先的超视距 高频极光雷达
