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

• Subject Area: Geophysics
• Term: from 2016 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 263649064

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?
