Abstract

This research studies the O₂ (a¹Δ_g) nightglow distribution in 1.27 μm to understand the dynamics of the atmosphere of Venus. Several factors were considered in the retrieval process, such as thermal emission of the lower atmosphere, reflection by the clouds. Results show deviation from SS-AS circulation mode: the area where horizontal flows from the dayside converge and where oxygen recombines and emits shifts from the midnight to 22–23 hours local time. This shift is caused by solar-induced thermal tide on Venus nightside. Some conclusions about the upper mesosphere dynamics are also presented.

O2 (а1Δg)金星夜侧1.27 μM气辉与上层中间层动力学

本研究通过研究1.27 μm的O2 (a1Δg)夜光分布来了解金星大气的动态。在反演过程中考虑了几个因素，如低层大气的热发射、云的反射。结果显示了与SS-AS环流模式的偏差:白天的水平气流汇聚的区域以及氧气重组和释放的区域从午夜转移到当地时间22-23小时。这种变化是由太阳在金星的夜侧引起的热潮汐引起的。本文还对上层中间层动力学作了一些总结。

期刊介绍： Solar System Research publishes articles concerning the bodies of the Solar System, i.e., planets and their satellites, asteroids, comets, meteoric substances, and cosmic dust. The articles consider physics, dynamics and composition of these bodies, and techniques of their exploration. The journal addresses the problems of comparative planetology, physics of the planetary atmospheres and interiors, cosmochemistry, as well as planetary plasma environment and heliosphere, specifically those related to solar-planetary interactions. Attention is paid to studies of exoplanets and complex problems of the origin and evolution of planetary systems including the solar system, based on the results of astronomical observations, laboratory studies of meteorites, relevant theoretical approaches and mathematical modeling. Alongside with the original results of experimental and theoretical studies, the journal publishes scientific reviews in the field of planetary exploration, and notes on observational results.
