Airglow and Auroral Studies of the Earth's Upper Atmosphere

这项研究旨在利用地面光学测量来研究高层大气。研究领域包括：1)从静止到扰动的地磁条件下高空热层动力学的测量，2)高空热层风场和温度场测量扩展到中层大气层，3)中性大气运动与电离层等离子体运动的相关性，4)所有这些情况下测量的行为与从头计算和经验模型的预测相比较。用于观测的仪器包括米尔斯通山和Laurel Ridge的两台双静态操作的法布里-珀罗涉仪、Laurel Ridge的一台新的全天多普勒干涉仪以及秘鲁阿雷基帕的第四台FFP干涉仪。这些测量将与模型相结合，以解释在高层大气中观察到的中性风的行为。

This research aims to study the upper atmosphere using ground-based optical measurements. The areas of investigation are: 1) measurements of upper thermosphere dynamics under geomagnetic conditions ranging from quiet to disturbed, 2) extension of the upper thermosphere wind and temperature field determinations to the middle atmosphere region, 3) correlation of the neutral atmosphere motion with those of the ionospheric plasma, and 4) comparisons of the measured behaviors in all these cases with predictions of ab- initio and empirical models. The instruments used for the observations include two Fabry-Perot Interferometers (FPIs) at Millstone Hill and Laurel Ridge operated bi-statically, a new all- sky Doppler interferometer at Laurel Ridge, and a fourth FPI at Arequipa in Peru. The measurements will be combined with models to account for the observed behavior of neutral winds in the upper atmosphere.
