The datasets of the Chinese Academy of Sciences(CAS)Flexible Global Ocean–Atmosphere–Land System(FGOALS-f3-L)model for the baseline experiment of the fully coupled runs in the Diagnostic,Evaluation and Characterization of Klima(DECK)common experiments of phase 6 of the Coupled Model Intercomparison Project(CMIP6)are described in this study.The CAS FGOALS-f3-L model team submitted the pi Control run with a near equilibrium ocean state for 561 model years,and 160-year integrations for three ensemble members of abrupt-4×CO2 and 1pct CO2,respectively.The ensemble members restart from the 600,650 and 700 model years in the pi Control run,respectively.The baseline performances of the model are validated in this article.The preliminary evaluation suggests that the CAS FGOALS-f3-L model can preserve the long-term stability well for a mean net radiation flux of 0.31 W m-2at the top of the atmosphere,and a limited decreasing trend of-0.03 W m-2/100 yr.The global annual mean SST is 16.45°C for the 561-year mean,with an increase of 0.03°C/100 yr.The model captures the basic spatial patterns of climate-mean SST and precipitation,but still underestimates the SST over the warm pool.The coupled model mitigates the precipitation bias in the ITCZ compared with the results from CMIP5.Moreover,the model’s climate sensitivity represented by the equilibrium climate sensitivity has been reduced from 4.5°C in CMIP5 to 3.0°C in CMIP6.All these datasets contribute to the benchmark of model behaviors for the desired continuity of CMIP. 展开更多
