This dataset contains six different reconstructions of total Arctic sea ice extent during the Instrumental Era. These reconstructions were produced using data assimilation of climate model output and temperature observations. The prior ensembles were drawn from climate model output from both the Community Climate System Model version 4 (CCSM4, Last Millennium simulation Landrum et al., 2013) and Max Planck Institute for Meteorology (MPI-ESM-P, Last Millennium simulation Taylor et al., 2012). Temperature observations were drawn from three different products: 25 HadCRUT, Berkeley Earth (BE, Rohde et al., 2013), and NASA Goddard Institute for Space Studies 26 (GISTEMP, Hansen et al., 2010). These reconstructions are published in Brennan et al. (2020). Brennan, M. K., Hakim, G. J., & Blanchard-Wrigglesworth, E. (2020). Arctic sea-ice variability during the instrumental era.
