Spectroscopic and Interferometric Studies of Middle Atmosphere Dynamics and Particle Precipitation Patterns Over the South Pole

摘要9614158 Sivjee该项目在南极洲南极维持一个红外分光光度计，一个八通道光子计数光度计和一个红外迈克尔逊干涉仪，以研究高层大气的动力学和化学。 通过测量气辉带发射的亮度和温度的变化，有可能探测行星波、重力波和潮汐波。 水平波结构是通过在几个方向上观察来研究的，同时在几个波长处进行这些测量，这些波长来自大气中的不同高度，提供了关于波活动的垂直范围的信息。 此外，用分光光度计观察不同高度的极光发射，可以深入了解极光沉淀电子来源的性质，以及这些不同来源如何随时间变化。 ***

Abstract 9614158 Sivjee This project maintains an infrared spectrophotometer, an eight channel photon counting photometer and an infrared Michelson interferometer at South Pole, Antarctica to study the dynamics and chemistry of the upper atmosphere. By measuring the variations in the brightness and temperature of airglow band emissions it is possible to detect planetary, gravity and tidal waves. The horizontal wave structures are studied by looking in several directions while making these measurements at several wavelengths, which come from different heights in the atmosphere, provides information on the vertical extent of the wave activity. Additionally, viewing the different altitude auroral emissions with the spectrophotometer is providing insight into the nature of the sources of the auroal precipitating electrons and how these different sources vary as a function of time. ***
