Perfect model simulations performed with EC-Earth3-CC using concentration-driven configuration. Ocean variables : fgco2, intpp, spco2, tos, sos, mlotst, areacello. Land variables: lai, nep, nbp, cLand Atmospheric variables: tas, pr, uas, vas Starting dates: 5 (1927; 1937; 1968; 2007; 2028) Ensemble size: 10 Length : 7 (years) Frequency output: monthly Simulations designed and produced at Barcelona Supercomputing Center. This work was funded by the European Union project H2020 Climate-Carbon Interactions in the Current Century (Grant 821003) All files follow the conventions for CF (Climate and Forecast) metadata and were generated with the CMOR library. Naming of variables follows the CMIP6 data request protocol.
