Early interior-surface-atmosphere interactions on the terrestrial planets (C05)

我们调查了挥发性物质的输送、撞击和内部过程如何影响地球早期大气的演变和形成宜居条件。为了实现这一点，我们应用耦合模型并模拟了从关键岩浆海洋时期到太古宙的大气气候和组成，在那里出现了生命和居住条件。因此，我们开发了一个最先进的气候化学模型，这在文献中是新的，我们实现了大气逃逸和放气过程的影响。我们的关键科学问题是，岩浆海洋阶段的持续时间是多久，蒸汽大气崩溃形成海洋的时间是什么时候？

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?
