Riometry in Antarctica and Conjugate Regions

马里兰大学将继续利用银河射电噪声吸收技术（riometry）对高磁纬电离层和磁层进行研究。几年前，他们开发了一种新的成像里程计，可以研究白天和云层下的极光形态。这些成像里程计目前正在加拿大的伊基鲁特使用；Sondestromfjord,格陵兰岛;南极，南极洲。此外，他们还在伊魁特、麦克默多和南极点操作宽波束测径仪，并在麦克默多和南极点操作极光光度计。在接下来的几年里，他们将提供在南极洲的英国哈雷湾站和澳大利亚戴维斯站建立成像测速仪所需的部分硬件，从而大大扩大覆盖范围。里程表与其他研究人员在这些地点操作的许多其他仪器协同工作。今后几年的主要研究重点将是漂移的极地极光斑块的特征及其与极帽对流的关系。＊＊＊

Abstract 9505823 Rosenberg The University of Maryland will continue their studies of the high magnetic latitude ionosphere and magnetosphere using galactic radio noise absorption techniques (riometry). Several years ago, they developed a new imaging riometer which allows the study of auroral morphology during daylight and through clouds. These imaging riometers are now being operated at Iqiluit, Canada; Sondestromfjord, Greenland; and South Pole, Antarctica. Additionally, they are operating broad beam riometers at Iqaluit, McMurdo and South Pole as well as auroral photometers at McMurdo and South Pole. In the next few years they will provide part of the hardware necessary to build imaging riometers at the British Halley Bay and the Australian Davis stations, both in Antarctica, thus considerably extending coverage. The riometers work synergistically with a number of other instruments which are operated at these sites by other investigators. A major focus of investigations over the next few years will be the characterization of drifting polar auroral patches and their relationship to polar cap convection. ***
