The datasets presented here aim at the examination of global ocean temperature and circulation response to atmospheric CO2 drawdown (from 400 to 200 ppmv) and Antarctic ice-sheet expansion (43 m of sea-level equivalent) across the middle Miocene climate transition.The data provided are climatological means obtained from the CCSM3 experiments named MMCO400, MMG200, MMCO200, MMG400, and PI. MMCO400 and MMG200 represent the periods before and after the middle Miocene climate transition, respectively. The design of MMCO200 is identical to that of MMCO400 except for the atmospheric CO2 concentration, which is set to 200 ppmv instead of 400 ppmv. The design of MMG400 is identical to that of MMG200, except for CO2, which is set to 400 ppmv instead of 200 ppmv. PI is a pre-industrial control run. See the description in the methods section of the associated manuscript for more details. All data are presented in NetCDF format. Datasets D1 to D5 (D6 to D10) contain CCSM3 ocean/ice (atmosphere) model data. Datasets D11 ...
