| In addition, the CMIP6 Historical Simulation has been added which will serve as the entry card for CMIP6 and as a benchmark for CMIP6-Endorsed MIPs. The historical simulation (1850-2014) will use the specific forcings consistent with CMIP6 which will be finalized on the timescales laid out in slide 10. The CMIP6 Historical Simulation has been introduced in addition to the DECK to better separate CMIP from a specific Phase of CMIP (see slide 4 for illustration and slide 5 for the main criteria for DECK and Historical Phase X). Both DECK and the CMIP6 Historical Simulation should be run for each model configuration used in the subsequent CMIP6-Endorsed MIPs. Future climate change scenarios will be run as part of ScenarioMIP with a Tier 1 that includes three different scenarios, spanning different possible futures. | In addition, the CMIP6 Historical Simulation has been added which will serve as the entry card for CMIP6 and as a benchmark for CMIP6-Endorsed MIPs.

| Under DCPP, Martin Ménégoz will perform parts of C3, the experiments that focus on the volcanic effect on decadal prediction. These experiments are very close to experiments performed in the context of SPECS and are coordinated with VolMIP. They consist in repeating the decadal hindcasts without the volcanic forcing of large eruptions. | Under DCPP, Martin Ménégoz will perform parts of C3, the experiments that focus on the volcanic effect on decadal prediction.
