抽象的。分析了高频有源极光研究计划(HAARP)加热装置高频修正实验中630 nm(红线)和557.7 nm(绿线)的气辉观测结果。我们提出了一个理论框架来理解磁天顶注入过程中朗缪尔声波和离子声波的产生。我们表明，在低密度电离层中观测到的HF诱导的气辉以及发射体积高度的降低与这一情景是一致的。
Abstract. Observations of airglow at 630nm (red line) and 557.7nm (green line) during HF modification experiments at the High Frequency Active Auroral Research Program (HAARP) heating facility are analyzed. We propose a theoretical framework for understanding the generation of Langmuir and ion acoustic waves during magnetic zenith injections. We show that observations of HF-induced airglow in an underdense ionosphere as well as a decrease in the height of the emitting volume are consistent with this scenario.
