The study of exoplanet atmospheres is the best (and only way) to study the chemistry, weather, climate, and formation histories of these foreign worlds. The study of exoplanets does not only inform the history of the particular planet but also sheds light on planet formation in general and places our own solar system in the galactic context. To date, most observations of these planets are either space-based (e.g. Hubble, Spitzer or James Webb Space Telescope) or ground-based (e.g. VLT/Keck). Both, space and ground-based observations probe complementary pressure regimes of the atmospheres. This said, to date, little work has been undertaken to combine both space and ground approaches. In this PhD project, the student will work on developing a new atmospheric retrieval code (i.e. atmospheric analysis tool) based on the TauREx 3 retrieval framework developed at UCL. The student is already trained in the analysis of high-resolution spectra data analysis and will be able to start with the algorithmic development immediately.

对系外行星大气层的研究是研究这些外来世界的化学、天气、气候和形成历史的最佳（也是唯一的方法）。对系外行星的研究不仅可以告知特定行星的历史，还可以揭示行星的一般形成，并将我们自己的太阳系置于银河系中。到目前为止，大多数对这些行星的观测都是基于太空（如哈勃，斯皮策或詹姆斯韦伯太空望远镜）或地面（如VLT/凯克）。空间和地面观测都探测大气的互补压力状态。尽管如此，迄今为止，在将空间和地面方法联合收割机结合起来方面所做的工作很少。在这个博士项目中，学生将致力于开发一个新的大气检索代码（即大气分析工具）的基础上，在UCL开发的TauREx 3检索框架。学生已经接受了高分辨率光谱数据分析的培训，并将能够立即开始算法开发。
