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

我们研究了挥发性传递、撞击和内部过程如何影响地球早期大气的演化和进入可居住条件的出现。为了实现这一目标，我们应用耦合模型并模拟从临界岩浆海洋时期到生命和宜居条件出现的太古代的大气气候和成分。因此，我们开发了一个最新的气候化学模型，这在文献中是新的，我们实现了大气逸出和放气过程的影响。我们的关键科学问题是，岩浆海洋阶段持续了多长时间蒸汽大气是什么时候坍塌形成海洋的？

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?
