We investigate how volatile delivery, impacts and interior processes could influence the evolution of Earth's early atmosphere and the emergence into habitable conditions. To achieve this we apply coupled models and simulate atmospheric climate and composition from the critical magma ocean period up to the Archean where life and habitable conditions emerged. We develop thereby a state-of-the-art climate-chemistry model which is new in the literature and we implement the effect of atmospheric escape and outgassing processes. Our key science questions are, what was the duration of the magma ocean phase and when did the steam atmosphere collapse to form the oceans?

我们研究挥发性物质的传递、撞击和内部过程如何影响地球早期大气的演化以及适宜居住条件的形成。为了实现这一目标，我们应用耦合模型并模拟从关键岩浆海洋时期到出现生命和宜居条件的太古宙的大气气候和成分。因此，我们开发了一种最先进的气候化学模型，这在文献中是新的，并且我们实现了大气逃逸和排气过程的效果。我们的关键科学问题是，岩浆海洋阶段的持续时间是多少？蒸汽大气何时塌陷形成海洋？
