This dataset combines model outputs from five experiments which aim at reconstructing the middle Eocene to early Oligocene greenhouse-icehouse transition (Toumoulin et al., 2021, Clim. Past).
Simulations are characterized by a 40 Ma paleogeography (Poblete et al., 2021, Earth-Sci. Rev.), different pCO2 (1120, 840, 560 ppm), and an antarctic ice-sheet or not. When present, antarctic ice-sheet is represented alone or associated with a sea-level decrease of -70 m, which is applied homogeneously to the 40 Ma paleogeography map. All experiments were performed with the general circulation model IPSL-CM5A2 (Sepulchre et al., 2020, Geosci. Model Dev.) and ran for 4000 years to a quasi-equilibrium state (change in deep ocean temperature < 0.1°C/century). Data are monthly averages over the last 100 years.
