HadCM3 general circulation model forced simulations of oscillating last glacial maximum forced with deglacial meltwater

This dataset contains HadCM3 model global forced simulations of the last glacial maximum, inputs and outputs, as used in the publication Rome et al. 2022 (DOI:10.1002/essoar.10511015.1). Seven simulations outputs are included under the names XOUPA, TFGBD_XOUPD, XOUPH, TFGBR_XOUPL, TFGBI, XOUPF and TFGBJ. The simulations were created using the general circulation model HadCM3 over the entire globe under last glacial maximum (21,000 years ago) conditions and forced with snapshots of meltwater derived from the early deglaciation (21,500 to 17,800 years ago). The outputs consist of sea-ice concentration, ocean overturning circulation, mixed layer depth, sea surface salinity, sea surface temperature, precipitation and surface air temperature. For reproducibility, the meltwater input files used for the forcing (lgm_inputs), the model input files (mw_inputs), the pre-industrial climatologies (pi_climate) and the crash diagnostics (crash_data) are included.
