Polar Anglo-American Conjugate Experiment

这笔赠款用于继续操作和分析根据前一笔赠款安装在南极洲哈雷湾站的高频相干散射雷达的数据。该雷达是极地英美共轭实验（PACE）的一部分，与拉布拉多鹅湾运行的几乎相同的雷达进行磁共轭。鹅湾雷达的经费由美国国家科学基金会大气科学部提供。除了共轭物镜外，该雷达的视场还包括南极站上方的区域。高频相干雷达可以探测和测量高层大气中过量电离斑块的速度，因此对研究极帽区动力学非常有用。PACE雷达首次提供了研究南北极帽中电离层同时行为的手段。

This grant provides for the continuing operation and analysis of data from the high frequency (HF) coherent scatter radar that was installed at Halley Bay Station, Antarctica under a previous grant. The radar, part of the Polar Anglo-American Conjugate Experiment (PACE) is magnetically conjugate to a nearly identical radar operated at Goose Bay, Labrador. Funding is provided for the Goose Bay radar by the Atmospheric Science Division of NSF. In addition to the conjugate objective, the radar has a field of view that includes the region above South Pole Station. HF coherent radars can detect and measure the velocity of patches of excess ionization in the upper atmosphere, and as a consequence they are very useful for studying the dynamics of the polar cap region. The PACE radars are for the first time providing the means to study the simultaneous behavior of the ionosphere in both the northern and southern polar caps.
