FAMOUS-BISICLES simulation data with interactive Northern Hemisphere ice sheets (21ka and 140ka)

This dataset contains model inputs and outputs from ensembles of simulations and sensitivity tests performed by FAMOUS-BISICLES of the Last Glacial Maximum (LGM; 21 kilo annum before present (ka BP)) and the Penultimate Glacial Maximum (PGM; 140 ka BP), as used in the publication Patterson et al., 2025 (https://doi.org/10.5194/egusphere-2024-3896).

These data were used to explore the sensitivity of the ice sheets to uncertain model parameters. The output of 120 ensemble members varying climate and ice sheet model parameters for each of the LGM and PGM are included as well as the results of sensitivity tests varying the spatial resolution and till water drainage rate. These simulations were created using the atmospheric general circulation model FAMOUS coupled to the BISICLES ice sheet model under LGM and PGM climate boundary conditions, including greenhouse gas concentrations and orbital parameters outlined in the PMIP4 (Paleoclimate Modelling Intercomparison Project - Phase 4) protocols (Kageyama et al., 2017 and Menviel et al., 2019).
