The Max Planck Institute for Meteorology (MPI-M) Emission-driven Large Ensemble (MPI-Edriven-LE) is based on the Earth system model MPI-ESM1-2-LR. This ensemble is forced by CO2 emissions in representing the interactive carbon cycle instead of the conventional prescribed CO2 concentration. In this emission-driven ensemble, the atmospheric CO2 concentration evolves in response to the strength of ocean and land carbon sink interactively (Li et al., 2021). This emission-driven ensemble simulations enable investigation of the global carbon cycle and the climate changes in the presence of internal variabilities of the Earth system. The following video illustrates that the atmospheric CO2 varies from seasonal to long-term scale in response to the emission and climate change https://www.dkrz.de/en/communication/galerie/Vis/esm/seasonal-variations-of-co2-under-climate-change. The full dataset can be found on https://esgf-data.dkrz.de/projects/mpi-edriven-le/ This work is supported by the European Union's Horizon 2020 research and innovation program "Climate-Carbon Interactions in the Current Century (4C)" and under grant agreement no. 821003 and "Coordinated Research in Earth Systems and Climate: Experiments, kNowledge, Dissemination and Outreach (CRESCENDO)" under grant agreement no. 641816. Simulations were performed at the German Climate Computing Center (DKRZ).
