Abstract

New analyses of Voyager spectra of Titan have led to improvements in the determination of abundances of minor constituents as a function of latitude and altitude. Ground-based microwave observations have extended the Voyager results for HCN, and have demonstrated that CO is mysteriously deficient in the stratosphere. The origin of the CH4, CO, and N2 in Titan's atmosphere is still unresolved. Both primordial and evolutionary sources are compatible with the available evidence.

摘要

对土卫六的旅行者号光谱进行的新分析，使得在确定次要成分的丰度随纬度和高度变化方面有了改进。地面微波观测扩展了旅行者号关于氰化氢的观测结果，并表明平流层中的一氧化碳存在神秘的不足。土卫六大气中甲烷、一氧化碳和氮气的来源仍未得到解决。原始来源和演化来源都与现有证据相符。
