Jake is working to understand the key long-term processes controlling the Archean Earth climate using PALEO, a 0D biogeochemical model. This is being done in parallel with short-term 3D modelling using the UM. We are hoping to model the climate models to develop parametrisations for atmospheric processes in PALEO and PALEO to provide input fluxes to the atmosphere of the 3D model, with the aim of better constraining the Archean climate. We are looking to further by investigating to a tidally locked analogue and how these configurations may diverge.
