Description
This data includes input and output fields of the Norwegian Earth System model simulations targeting the Eocene-Oligocene boundary, and the data accompanies a scientific article with the same name (DOI 10.1073/pnas.2115346119). This data is aimed to provide users enough data to reproduce the figures appearing in the article and to analyze the steady state behavior beyond what is discussed in the article. We also provide the ocean bathymetry and atmospheric topography that allows others to create a model setup similar to what is used in the article.
For most files there are two output periods 1450-1500 is a common period for the experiments: Late Eocene and cases 1-5. This period the average over the last 50 years of the experiments that were branched of the common spinup at year 1000. The latter period 2650-2700 includes continuation of the Late Eocene and Case 2 simulations and their lower CO2 counterparts (branched of from their parent simulations at year 2000). For more information of the simulations and the setup, we refer to the parent article.
In addition to the output files, we also share the grid files of the ocean model (grid*.nc) and the topography used by the atmospheric model (ATM_TOPO.nc). Note that we did not change the land mask between the experiments which is why there is only one ATM_TOPO, but one grid file per each experiment.
