Multi-Station Auroral Spectroscopy

在这项研究中，极光将从格陵兰岛的Godhavan（在格陵兰岛Sondre Stromfjord西北约290公里的磁子午线附近）用成像光谱仪观察。同时，非相干散射雷达和其他光学仪器将在桑德雷·斯特罗姆峡湾的磁天顶观测到同样的极光。该方法测量了源发射强度与高度的关系，同时用雷达对粒子束进行了测量。第一个科学目标是研究电子束与发射高度的关系。还将进行极光弧和热层效应的研究。计划进行两次冬季战役。一个专门的为期两周的“航空”战役计划中，雷达将主要用于寻找磁场。此外，该卫星还计划在另外两个为期两周的低月期使用“共享”雷达时间。第一场战役将集中在420-800纳米光谱区域。整个光谱的高度分布将被测量。第二个活动的光谱区域将从第一个活动的结果演变而来。

In this study the aurora will be viewed from Godhavan, Greenland (near the magnetic meridiana distance ~290km northwest of Sondre Stromfjord, Greenland) with an imaging spectrometer. Simultaneously the incoherent scatter radar and other optical instruments will view the same aurora in the magnetic zenith at Sondre Stromfjord. The method provides measurements of source emission intensities versus altitude, while simultaneous measurements of the particle beam is made with the radar. The first scientific objective is a study of electron beam versus emission heights. Studies of auroral arcs and thermospheric effects will also be performed. Two winter campaign periods are planned. A dedicated two week "aeronomy" campaign is planned where the radar will be predominantly operated looking up the magentic field. Operation is also planned for two additional two-week, low moon, periods with "shared" radar time. The first campaign will concentrate on the 420-800 nm spectral region. Height distributions of the entire spectrum will be measured. The spectral region for the second campaign will evolve from the results of the first.
