I will be studying the Aurora Australis (southern lights) from the South Pole. It encircles the Antarctic continent and the dayside aurora in particular will be nearly overhead, enabling detailed studies of its dynamics in relation to solar activity. I will use a scanning photometer which will scan the meridian through the south magnetic and geographic poles continuously through each 6-month long austral winter, monitoring both auroral and airglow emissions- for comparisons with my similar recent studies from the northern polar cap and the Aurora Borealis. I will also exploring the structure and dynamics of the polar upper atmosphere  in both hemispheres with a view to gaining further understanding of the whole global circulation at  high latitudes.

我将在南极研究南极光。它环绕着南极大陆，特别是日侧极光将几乎在头顶上，从而能够详细研究其与太阳活动的关系。我将使用一个扫描光度计，它将通过南磁极和地理极点连续扫描子午线，通过每6个月的南极冬季，监测极光和气辉发射-与我最近在北方极冠和北极光的类似研究进行比较。我也将探索两极高层大气在两个半球的结构和动力学，以期获得在高纬度的整个全球环流的进一步了解。
