Exoplanets are now being discovered in profusion. To understand their character, however, we require spectral models and data. These elements of remote sensing can yield temperatures, compositions and even weather patterns, but only if significant improvements in both the parameter retrieval process and measurements are made. Despite heroic efforts to garner constraining data on exoplanet atmospheres and dynamics, reliable interpretation has frequently lagged behind ambition. I summarize the most productive, and at times novel, methods used to probe exoplanet atmospheres; highlight some of the most interesting results obtained; and suggest various broad theoretical topics in which further work could pay significant dividends.
系外行星现在正在大量被发现。然而,为了了解它们的特性,我们需要光谱模型和数据。这些遥感元素可以提供温度、成分甚至天气模式,但前提是在参数检索过程和测量方面都取得重大改进。尽管人们努力收集有关系外行星大气和动力学的约束数据,但可靠的解释经常落后于雄心壮志。我总结了探测系外行星大气最有效、有时甚至是新颖的方法;强调了获得的一些最有趣的结果;并提出了一些广泛的理论课题,在这些课题中进一步的工作可能会带来显著的回报。
