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.
