iCESM1.2 Cenomanian Turonian simulations with varying pCO2

This dataset contains ocean and atmosphere outputs, including water isotopes (NetCDF files) from modeling experiments with realistic Cenomano-Turonian paleogeography and varying pCO2, and notebook (Scripts_Cretaceous.tar) to produce analysis from Sarr et al. (2025), Paleoceanography and Paleoclimatology paper. The simulations have been run using the iCESM1.2 Earth System Model (f19_g16). It includes 3 ocean-atmosphere simulations. Data are monthly averages over the last 100 years of the simulations. The code for the water isotope enabled iCESM1.2 used to obtain those ouputs is available at https://github.com/NCAR/iCESM1.2
