*: Using the full RT grid model and the outgassing laws of Nikolaou et al. (2019).
a The CO2 content differs between the ET and Nicolaou-simulations. Thus, the content is given in brackets divided by slashes as ET/Nicolaou).
b : In the ET-simulations, all CO2 is assumed to be in the melt initially. In the Nicolaou (Ni)-simulations, however, we already start with a substantially outgassed CO2 atmosphere. For better comparison, we thus give here in curly brackets for the Nicolaou-simulation also the initial melt fraction assuming that all CO2 is dissolved.
