The atmospheric composition (and other conditions) should be prescribed as in the historical run (expt. 3.2) and the RCP4.5 scenario (expt. 4.1) of the long-term suite of experiments. Ocean initial conditions should be in some way representative of the observed anomalies or full fields for the start date. Land, sea-ice and atmosphere initial conditions are left to the discretion of each group.10-year hindcast/prediction initialized in year 1965ad6c37b8-d3a5-11df-837f-00163e9152a5--cmip5ABDECADAL1965Metafor CMIP5 Questionnairemetafor-qcim.1.activity.NumericalExperimentExperimentAB3Ensemble of 10-year hindcasts and Predictions.
