Summary
[ Derived from parent entry - See data hierarchy tab ]

We simulated the Late Cretaceous climate using COSMOS in a coupled atmosphere-ocean configuration with different CO2 levels: 1120ppm (4x pre-industrial level, PI, of 280ppm), 840ppm and 560ppm. Atmosphere component ECHAM5 resolution was T31 while ocean component mpiom - GR30 with 40 vertical levels. We used Markwick and Valdes [2004] paleogeography as an input boundary condition to simulate climate changes during the Plenus cold event (~94 Ma). In particular, we investigated changes in the surface salinity and temperature in the Western Interior Basin due to atmospheric CO2 level changes. Here we present precipitation (precip), evaporation (evap), surface temperature (tsurf), surface temperature of water (tsw), sea surface temperature (sst), salinity (SAO), winter and summer sea ice compactness (SICOMO), sea surface currents (zonal - UKO, meridional - VKE; m/s) and ocean currents (cm/s; for 1120 and 560 simulations) of the last 100 years of simulations. Data shown here were used in the analyses of Sagemann et al. [2024; https://doi.org/10.1016/j.cretres.2023.105798]. More details about the simulation set-up and model description can be found therein.

Note that the units in the attributes of the variables sea_water_{x/y}_velocity and sea_water_{x/y}_velocity-atSurface should be the other way around and as they are specified in metadata (so m s-1 for sea_water_{x/y}_velocity-atSurface and cm s-1 for sea_water_{x/y}_velocity).
