Inputs, boundary conditions, and ouputs files of the experiments described in Sepulchre et al. manuscript "IPSL-CM5A2. An Earth System Model designed for multi-millennial climate simulations" submitted for publication to Geoscientific Model Development: https://www.geosci-model-dev-discuss.net/gmd-2019-332 The 90Ma_IPSLCM5A2_inputs.tar tarball contains the input and boundary files used to run the 3,000-year Cretaceous experiment. The output_files.tar tarball contains the netcdf output files of the preindustrial, historical and Cretaceous simulations analyzed in the manuscript. Diagnoses are presented through a Jupyter notebook that can be retrieved and played interactively here
