COSMOS model Late Cretaceous surface temperature results with different CO2 levels and gateway configurations

Here we publish simulated Late Cretaceous (~70 Ma) annual mean surface temperatures (tsurf) with different (280-1680 ppm) CO2 levels, annual mean surface temperatures with different gateway configurations between the Arctic Ocean and North proto-Atlantic basin, as well as summer (JJA) and winter (DJF) mean surface temperatures with 840 ppm CO2 level. All data were averaged over the period of 100 years. The climate data has been produced with COSMOS (ECHAM5/MPIOM/OASIS3). The atmosphere component ECHAM5 was run in the resolution of T31/L19, while the ocean model MPIOM in the resolution of GR30 (bipolar orthogonal curvilinear grid with a formal resolution of ~3.0°x1.8°). OASIS3 is responsible for coupling between the atmosphere and ocean components. The Late Cretaceous setup is based on the Markwick and Valdes (2004, doi:10.1016/j.palaeo.2004.06.015) paleogeography. More details about a model setup can be found in Niezgodzki et al. (2017, doi:10.1002/2016PA003055). Additionally, we have prepared the .xlsx file where we provide the details of the locations of data points as well as reconstructed temperatures as used in a model-data comparison. These data are the modified data from Upchurch et al. (2015, doi:10.1130/G36802.1). For more details about the procedure used to modify the original data set, see Niezgodzki et al. (2017, doi:10.1002/2016PA003055).
