Airglow and Auroral Studies of the Earth's Upper Atmosphere

这项研究的目的是利用地面光学测量来研究高层大气。研究的领域是：1)测量地磁条件下的上层热层动力学，从平静到干扰，2)将上层热层风和温度场的确定扩展到大气中部区域，3)中性大气运动与电离层等离子体运动的相关性，4)在所有这些情况下测量的行为与从头算和经验模型的预测进行比较。用于观测的仪器包括位于磨石山和月桂岭的两台双静态运行的法布里-珀罗干涉仪，位于月桂岭的一台新的全天多普勒干涉仪，以及位于秘鲁阿雷基帕的第四台法布里-珀罗干涉仪。测量结果将与模型相结合，以解释观测到的高层大气中中性风的行为。

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.
