Southern Hemisphere winter sea ice concentration simulated by HadCM3 to best explain the early last interglacial Antarctic isotope peak
The file contains Southern Hemisphere winter (September) sea ice concentration (sic) from a simulation performed using the isotope-enabled HadCM3 climate model forced with early last interglacial boundary conditions, centred approximately 128,000 years ago. The resulting sic represents a reduction in winter sea ice area of approximately 54% relative to pre-industrial and is proposed as the best explanation for the Antarctic ice core data from 128,000 years ago. The spatial pattern of sea ice retreat was determined using a large ensemble of model experiments and a pattern search optimization approach to match the last interglacial ice core isotope peak. Further details can be found in the published manuscript ( https://doi.org/10.1002/2017GL074594).

Methodology:
This is output from a simulation using the isotope-enabled HadCM3 climate model forced with early last interglacial boundary conditions (orbital configuration and greenhouse-gas concentrations), centred approximately 128,000 years ago. Sea ice concentration has been re-gridded from the native global model grid to a higher resolution latitude-longitude grid covering the latitude range from 52.5 to 80.5 deg S. Further details can be found in the published manuscript ( https://doi.org/10.1002/2017GL074594).
Data quality:
Masked NaN values represent grid points that are land.
The grid is 1445x113 in longitude, latitude.
