This item is part of the Climate model data presented in 'Acceleration of northern ice sheet melt induces AMOC slowdown and northern cooling in simulations of the early last deglaciation' collection.

Dataset description

This dataset contains output from a set of two published global climate simulations that investigate the role of ice sheet melting in the onset of Heinrich Stadial 1 ocean circulation and climate changes ~18.5 thousand years ago. The simulations were run with the HadCM3 general circulation model at the University of Leeds. Here, the simulations are named 'lgm_control' (set up to simulate the climate of 21 ka) and 'hs1', which is the simulation presented in the associated manuscript: Ivanovic, R. F., Gregoire, L. J., Burke, A., Wickert, A. D., Valdes, P. J., Ng, H. C., et al. (2018). Acceleration of northern ice sheet melt induces AMOC slowdown and northern cooling in simulations of the early last deglaciation. Paleoceanography and Paleoclimatology. https://doi.org/10.1029/2017PA003308. The hs1 simulation is the same as lgm_control, but it also includes a transient ice meltwater flux to the ocean derived from the ICE-6G_C global ice sheet history. The data is provided in NETCDF3 format within zipped directories corresponding to the two simulations and the routing of ICE-6G_C meltwater. For each simulation, we provide the freshwater forcing files (i.e. model input) and model output. Model output is provided as time-series for a range of ocean, atmosphere and vegetation data. See the accompanying README.txt for a list of supplied output variables as well as more information on the directory structure for the data.
