Riometry in Antarctica and Conjugate Regions

摘要9505823马里兰州大学的罗森博格将继续利用银河系无线电噪声吸收技术(RIT)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测速仪，可以研究白天和云中的极光形态。这些成像测速仪现在正在加拿大的伊基卢特、格陵兰岛的桑德勒姆峡湾和南极洲的南极运行。此外，他们还在Iqaluit、McMurdo和南极运行宽束测光仪，并在McMurdo和南极运行极光光度计。在接下来的几年里，他们将提供在南极洲的不列颠哈雷湾和澳大利亚戴维斯站建造成像测速仪所需的部分硬件，从而大大扩大覆盖范围。测力仪与其他一些仪器协同工作，这些仪器由其他调查人员在这些地点操作。今后几年的一个主要研究重点将是极光漂移斑块的特征及其与极冠对流的关系。***

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. ***
