Joint Incoherent-Scatter-Radar and Spectroscopic- Interferometric Investigations of Auroral Processes Over Sondrestromfjord

9320426 Sivjee该奖项是对极地热层大气成分与极光电子沉淀之间相互作用的联合雷达和光学研究。 后者通过一些高层大气成分的离解、激发和电离等过程耗散其大部分能量。 反过来，这些过程的副产品与环境空气颗粒相互作用，改变极地热层的组成和热力学。 所有这些高层大气极光过程都可以通过以下两种方法加以研究：利用极光区的非相干散射雷达探测对极光电离剖面进行地面遥感测量，同时对极光电子激发N2、O2、O和N的光学特征进行孔视光谱和干涉测量观测。 这些研究的数据库将根据对格陵兰Sondrestromfjord上空极光显示的ISR和光谱干涉观测建立。 ***

9320426 Sivjee This award is for joint radar and optical investigations of the interactions between the atmospheric constituents in the polar thermosphere and precipitating auroral electrons. The latter dissipate most of their energy through a combination of processes involving dissociation, excitation and ionization of some of the upper atmospheric constituents. In turn, the byproducts of these processes interact with ambient air particles to modify polar thermospheric composition and thermodynamics. All these upper atmospheric auroral processes can be investigated by combining ground-based remote sensing measurements of auroral ionization profiles using incoherent scatter radar (ISR) sounding of the auroral region, and concurrent bore-sighted spectroscopic and interferometric observations of the optical signatures of the auroral electron excitation of N2, O2, O and N. The data base for these studies will be constructed from the ISR and Spectro- interferometric observations of auroral displays occurring over Sondrestromfjord in Greenland. ***
