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

9320426 Sivjee该奖项是为了联合雷达和光学研究极地热层大气成分与极光电子沉淀之间的相互作用。后者通过涉及一些高层大气成分的解离、激发和电离的组合过程耗散其大部分能量。反过来，这些过程的副产品与周围空气颗粒相互作用，改变了极地热层的组成和热力学。利用非相干散射雷达（ISR）探测极光区域的地面遥感测量极光电离剖面，以及同时对N2、O2、这些研究的数据库将根据ISR和光谱干涉法对格陵兰岛sondrestrom峡湾发生的极光现象的观测建立。＊＊＊

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. ***
