Riometry in Antarctica and Conjugate Regions

该项目将继续并扩大对高层大气，特别是极光现象的研究，使用测光和测速技术。PI开发了一种新的成像里程计(相对电离层不透明度计)系统，称为IRIS(电离层研究成像里程计)。最初的两个IRIS安装在格陵兰岛的南极站和Sondre Stromfjord。第三个IRIS将于今年晚些时候安装在加拿大西北部的Iqiluit。在南极、麦克默多和伊基卢特，还有在几个频率上工作的宽束测光仪，以及在南极和麦克默多的极光光度计。Iqiluit是南极的磁力共轭。这些仪器构成了一个独特的网络，用来同时研究两个磁半球的极光效应。首席研究员是一位在大气中沉淀电子的影响方面受到国际尊敬的专家。

This project will continue and expand the study of the upper atmosphere, especially auroral phenomena, using photometry and riometric techniques. The PI has developed a new imaging riometer (relative ionospheric opacity meter) system called IRIS (Imaging Riometer for Ionospheric Studies). The first two IRIS's were installed at South Pole Station and Sondre Stromfjord, Greenland. A third IRIS will be installed at Iqiluit, NWT, Canada later this year. There are also broad-beam riometers operating at several frequencies at South Pole, McMurdo and Iqiluit as well as auroral photometers at South Pole and McMurdo. Iqiluit is the magnetic conjugate to South Pole. These instruments constitute a unique network with which to study auroral effects in both magnetic hemispheres simultaneously. The principal investigator is an internationally respected expert on the effects of precipitating electrons on the atmosphere.
