Abstract

The night airglow spectrum of Venus in the ultraviolet is dominated by the v' = 0 progressions of the gamma and delta bands of nitric oxide. The bands are produced by two-body radiative recombination of nitrogen and oxygen atoms. Since the source of these atoms is in the dayside thermosphere, the night airglow is a tracer of the day-to-night thermospheric circulation. The airglow is brightest at equatorial latitudes, and at longitudes on the morning side of the antisolar meridian.

摘要

金星夜间的紫外空气辉光光谱主要由一氧化氮的γ带和δ带的 v' = 0 跃迁组成。这些带由氮和氧原子的双体辐射复合产生。由于这些原子的来源在白天的热层中，因此夜间空气辉光是日-夜热层环流的示踪剂。在赤道地区，以及在与太阳相反的子午线的早晨一侧的经度上，空气辉光最亮。
