The Community Earth System Model (CESM) version 2.1 is a world-class coupled climate system model that includes components for the atmosphere, ocean, terrestrial system, river run-off, and fully active glaciers (Danabasoglu et al. 2020). This version of CESM was used in many experiments as part of the Coupled Model Intercomparison Project 6 (CMIP6, Eyring et al. (2016)) including the Ice Sheet Model Inter-comparison Project 6 (ISMIP6).

These data come from historical simulations (1950–2014) and future projections (2015–2100) using the fully-coupled earth system model, including an active ice sheet model (the Community Ice Sheet Model, or CISM, Lipscomb et al. (2019)) with feedbacks to the atmosphere, land, and oceans.  We have provided data from these two transient experiments to the community through Ghub for analysis and to force uncoupled ice sheet models.
