Observations in the visible and near-infrared of upper-atmospheric emissions above South Pole Station will be used to study the heating effects of auroral electrical currents in the ionosphere as well as planetary waves and atmospheric tides. The project is particularly timely for two reasons: first the sun is now in the period of maximum activity and secondly, because NASA will launch the TIMED (Thermosphere, Ionosphere and Mesosphere Energetics and Dynamics) satellite in December, 2000. TIMED is designed to study just those parts of the atmosphere that that Professor Sivjee's project will. TIMED will provide data on the temperature, winds and tides of the Earth's upper atmosphere, especially above the poles as it passes overhead; however, as is often the case with satellites, it is difficult to differentiate between variations in location or time. The South Pole ground-based observations will be valuable in sorting out the time-location question.

对南极站上空高层大气发射的可见光和近红外观测将用于研究电离层极光电流以及行星波和大气潮汐的加热效应。 该项目特别及时，原因有二：第一，太阳现在正处于最活跃的时期，第二，因为美国航天局将于2000年12月发射TIMED（热层、电离层和中间层能量学和动力学）卫星。 TIMED的目的是研究Sivjee教授的项目所涉及的大气层的那些部分。 TIMED将提供地球高层大气的温度、风和潮汐的数据，特别是当它从头顶经过时在两极上方;然而，与卫星的情况一样，很难区分位置或时间的变化。 南极的地面观测对解决时间-地点问题将是很有价值的。
