We provide the results of 11 Late Cretaceous climate simulations (Tab. 1 in Niezgodzki et al. [2019, doi:10.1016/j.gloplacha.2019.03.011]) produced with COSMOS in a coupled atmosphere-ocean configuration. Five of these experiments use a 3 x pre-industrial (PI) CO2 level (840 ppm) while 6 of them were run with 4xPI CO2 (1120 ppm). The experiments with the same CO2 levels differ by gateway configurations between the Arctic Ocean and North proto-Atlantic basin. In spin-up experiments we employ Maastrichtian (~70 Ma) paleogeography of Markwick and Valdes [2004, doi:10.1016/j.palaeo.2004.06.015]. More information about model scenarios and model set-up can be found in Niezgodzki et al. [2019, doi:10.1016/j.gloplacha.2019.03.011]. Here we publish simulated winter (DJF) surface temperatures (tsurf) and salinity (SAO), averaged March-April (Ma-Ap) sea surface temperature (THO) and SAO and monthly sea-ice compactness (SICOMO) of each experiment. Additionally, for two gateway configurations we show DJF and summer (JJA) 10m meridional (v10) and zonal (u10) wind speeds as well as JJA shortwave net surface radiation (srads), net clear sky surface radiation (srafs), longwave net surface radiation (trads) and clear sky surface radiation (trafs).
