In the first part of the project, the scientist will be tasked with building a comprehensive, sharable repository of example CDR model implementations. The repository of CDR implementations will encompass terrestrial and marine methods. For this, we will use the outcomes of ongoing projects that we are involved in, notably RESCUE and CDRmare and CDRterra, but also collaborate with international CDR experts in the context of CDRMIP.
In the second part of the project, the scientist will be analysing the multi-model ensemble simulations of CDRMIP to identify robustness of model responses and identify poorly constrained processes to inform future model development as well as scenario designs. The new CDRMIP model simulation, will allow for the analysis of portfolio implementations of CDR. The simulations will be a combination of idealised overshoot scenarios and realistic but single CDR implementation scenarios. We will complement these efforts with additional simulations with an Earth system model to understand each method's individual efficacy and side effects, and their respective additionalities.
