Data assimilation products by using multiple climate model simulations and different combinations of proxies

This dataset of the climate reconstruction by data assimilation using isotope ratios provides annual surface air temperature, precipitation amount, and other climate variables during 850–2000. Two isotopes-incorporated atmospheric general circulation models and 129 isotopic proxy data (65 corals, 43 ice cores, and 21 tree-ring cellulose) were used in this study. There are nine experiments using three type of simulations and three combinations of proxies. The associated publication: Shoji, S., Okazaki, A., &amp; Yoshimura, K. (2020).
