Exploring dynamic shifts in North Atlantic climate using CESMv1.2 time slice simulations of MIS-11c

Data are from a series of time-slice simulations using the Community Earth System Model (CESM) v1.2.2 run on the HLRN supercomputing systems. This configuration uses a coupled atmosphere, ocean, land, and sea-ice model to simulate many facets of climate at relatively high resolution (approx. 1° in t...

Description
Summary:Data are from a series of time-slice simulations using the Community Earth System Model (CESM) v1.2.2 run on the HLRN supercomputing systems. This configuration uses a coupled atmosphere, ocean, land, and sea-ice model to simulate many facets of climate at relatively high resolution (approx. 1° in the ocean and sea ice, 1.9° latitude by 2.5° longitude in the land and atmosphere). A baseline preindustrial control simulation was integrated under constant 1850 solar and greenhouse gas conditions for 2500 years. Time slice simulations corresponding to key insolation minima and maxima during the Marine Isotope Stage 11 (MIS-11) interglacial were branched from year 1500 of this simulation and run for 1000 additional years under the new forcing conditions. Only orbital parameters (longitude of perihelion, obliquity, and eccentricity) and key greenhouse gases (carbon dioxide, methane, and nitrous oxide) were altered between simulations. The data here represent a selection of calculated output fields including 2m air temperatures, total (convective + non-convective) precipitation, total (stationary + transient) eddy heat flux, and wind velocity at the 300hPa atmospheric pressure level. These fields were used to create plots in Crow et al. (2022), a manuscript submitted to Climate of the Past.
