Data from runs of model IPSL-CM5A as part of the PDRMIP project. Model version is IPSL-CM5A. The model has been run by CNRS, The National Centre for Scientific Research, Paris France. Documentation of the IPSL-CM5A model can be found in https://doi.org/10.1007/s00382-012-1636-1 . IPSL-CM5A has delivered data on the base experiment, for the core experiments CO2x2 (doubling of CO2), CH4x3 (tripling of methane), Solar (2% increase in incoming solar radiation), BCx10 (tenfold BC) and Sulx5 (quintupling of Sulphate), the regional experiments BCx10asia (tenfold BC over asia), Sulx10asia (tenfold Sulphate over Asia), Sulx10eur (tenfold Sulphate over Europe), and in addition a Sulx10 (Global tenfold Sulphate) experiment. All experiments have been performed with both coupled and fsst ocean settings.
