摘要

现在已经确定，从地面测量的极光发射是极化的。这种两极分化所提供的信息的问题仍有待探讨。在这篇文章中，我们展示了光学偏振计和几个地面仪器之间协调运动的结果，包括磁力计、EISCAT甚高频雷达和可见光域的互补亮度计(Ninox)。我们表明，在E区，极化是电离层电流、速度和动力学的一个很好的指标。

The polarisation of auroral emissions: A tracer of the E region ionospheric currents

It is now established that auroral emissions as measured from ground are polarised. The question of the information given by this polarisation is still to be explored. In this article, we show the results of a coordinated campaign between an optical polarimeter and several ground based instruments, including magnetometers, the EISCAT VHF radar and complementary luminance meters in the visible domain (Ninox). We show that in the E region, the polarisation is a good indicator of the ionospheric currents, velocity and dynamics.
