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（IRIS），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伊卡伊特使用；Sondestromfjord,格陵兰岛;南极，麦克默多和所有六个自动地球物理观测站（AGO）由美国国家科学基金会在南极洲运作。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。它们还为位于南极洲的英国哈雷湾站和澳大利亚戴维斯站提供了成像测速仪，从而大大扩大了覆盖范围。在接下来的几年里，他们还将为英属艾格斯群岛的一些岛屿建造成像里程计系统。这些仪器与其他研究人员在所有这些地点操作的许多其他仪器协同工作。* * *

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 (IRIS) which allows the study of auroral morphology during daylight and through clouds. These imaging riometers are now being operated at Iqaluit, Canada; Sondestromfjord, Greenland; South Pole, McMurdo and in all six of the Automatic Geophysical Observatories (AGO) operated by NSF in Antarctica. Additionally, they are operating broad beam riometers at Iqaluit, McMurdo and South Pole as well as auroral photometers at McMurdo and South Pole. They have also provided imaging riometers for the British Halley Bay and the Australian Davis stations, both in Antarctica, thus considerably extending coverage. In the next few years they will also build imaging riometers systems for some of the British AGOs. The instruments work synergistically with a number of other instruments which are operated at all of these sites by other investigators. ***
