Description

The Marine Isotopic Stage 3 (MIS 3 - between 27.8 - 59.4 thousand of years before present, hereafter ka) was characterised by millennial-scale climate fluctuations, also known as Dansgaard-Oeschger (D-O) oscillations. During D-O events, atmospheric and oceanic conditions alternated between warm interstadial (of up to 10-16 degrees C increase in air temperatures over Greenland) and cold stadial states (Dansgaard et al., 1993; Huber et al., 2006; Kindler et al., 2014). This dataset contains model outputs for four MIS 3 simulations run with the Bristol version of the Hadley Centre Coupled Model3 (HadCM3b). The model outputs are presented as netCDF files and contain the following variables: surface temperature, ocean temperature, Atlantic Meridional Overturning Circulation (AMOC), sea ice concentration, salinity and mixed layer depth.. The four simulations show D-O like behaviour, spontaneous D-O type oscillations. This work was funded by the European Union's Horizon 2020 research and innovation programme under grant agreement no. 820970.
