Data from runs of the model NCAR-CESM1-CAM4 performed in the project PDRMIP. Model version is CESM1.0.3 atmosphere: CAM4, ocean: SOM, sea ice CICE, land CLM4. The model has been run by CICERO, Center for International Climate Research, Oslo, Norway. Documentation of the CESM1 model can be found here https://www.cesm.ucar.edu/models/cesm1.0/. NCAR-CESM 1-CAM4 delivered data on the base experiment, for the core experiments CO2x2 (doubling of CO2), CH4x3 (tripling of methane) and Solar (2% increase in incoming solar radiation), BCx10 (tenfold BC), Sulx5 (quintupling of Sulphate), regional experiments BCx10asia (tenfold BC over asia), Sulx10asia (tenfold Sulphate over Asia), Sulx10eur (tenfold Sulphate over Europe) and phase 2 experiments CFC11 (from present day mixing ratio to 5ppb CFC11), CFC12 (from present day mixing ratio to 5ppb CFC12), N2O1p (from present day mixing ratio to 1ppm) and BCslt (as BCx10, but with reduced atmospheric lifetime of BC) . All experiments have been performed with both coupled and fsst ocean settings.
