摘要。高空核爆炸（HANEs）和地磁风暴可以产生大规模的相对论性粒子注入内部辐射带。人们认识到，这些bb10兆电子伏特捕获电子通量的大幅增加会缩短低地球轨道卫星的使用寿命，威胁到大量宝贵的人口。因此，正在进行研究，以实现人类对辐射带的实际控制，称为“辐射带补救”。这里我们考虑RBR系统运行1天或10天的高层大气后果。rbr强迫的中性化学变化，导致NOx增强和Ox消耗，在降水的时间尺度上是显著的，但通常不持久。这些变化的幅度、时间尺度和高度并不比在大型太阳质子事件中观察到的更重要。相比之下，rbr操作将导致异常强烈的高频停电，大约在操作时间的前半段，对无线电通信和导航系统造成大规模中断。虽然中性大气的变化不是特别重要，但HF干扰可能是政策制定者考虑的一个重要领域，特别是在自然注入的补救方面。
Abstract. High altitude nuclear explosions (HANEs) and geomagnetic storms can produce large scale injections of relativistic particles into the inner radiation belts. It is recognised that these large increases in >1 MeV trapped electron fluxes can shorten the operational lifetime of low Earth orbiting satellites, threatening a large, valuable population. Therefore, studies are being undertaken to bring about practical human control of the radiation belts, termed "Radiation Belt Remediation" (RBR). Here we consider the upper atmospheric consequences of an RBR system operating over either 1 or 10 days. The RBR-forced neutral chemistry changes, leading to NOx enhancements and Ox depletions, are significant during the timescale of the precipitation but are generally not long-lasting. The magnitudes, time-scales, and altitudes of these changes are no more significant than those observed during large solar proton events. In contrast, RBR-operation will lead to unusually intense HF blackouts for about the first half of the operation time, producing large scale disruptions to radio communication and navigation systems. While the neutral atmosphere changes are not particularly important, HF disruptions could be an important area for policy makers to consider, particularly for the remediation of natural injections.
