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.

该项目将继续并扩大对上层的研究 大气，特别是极光现象， riometric技术。 PI开发了一种新的成像仪 IRIS（相对电离层不透明度计）系统 电离层研究用电离仪）。 前两个IRIS是 安装在南极站和格陵兰岛的Sondre Stromfjord。 第三个IRIS将于今年晚些时候在加拿大西北部的Iqiluit安装 年 也有宽束riometers操作在几个 在南极，麦克默多和伊奇卢特以及极光频率 南极和麦克默多的光度计。 Iqiluit是磁性的 与南极共轭。 这些工具构成了一个独特的网络， 极光效应同时出现在两个磁半球。 的 首席研究员是一位国际知名的专家， 电子在大气中的沉淀效应。
