Abstract: This dataset contains the temperature reconstruction at the West Antarctic Ice Sheet (WAIS) Divide reported by Cuffey et al. (2016) in PNAS. Five files contain 1) the primary reconstruction (Eq. 2 of that publication), combining information from borehole temperatures, deuterium isotopic content of ice, and nitrogen-15 content of trapped diatomic nitrogen gas; 2) the primary reconstruction with higher-frequency content restored; 3) the lower limit of the primary reconstruction; 4) the upper limit of the primary reconstruction; and 5) and the primary reconstruction with added perturbations.
