Ice core oxygen isotope record and its three components from the Qiangtang No. 2 glacier, central Tibetan Plateau

In November 2021, we drilled five ice cores from the saddle of the Qiangtang No. 2 glacier (33.31^oN, 88.71^oE, 5854 masl). The data include the oxygen isotope anomaly sereis derived from the top 7.3 m of core-4 (QT2C4). The Singular Spectrum Analysis (SSA) method is also applied to distangle major modes in the record. Time series of the derived three compoments are also included in the dataset. In addition, simulated annual precipitation δ18O time series at the nearest grid to the ice core site between 1979-2020, including three isotope-enable models nudged by three different reanalysis products is also provided. A full descirption of the model setup and the full set of the simulation data are from Bong, H., Cauquoin, A., Okazaki, A., Chang, E. C., Werner, M., Wei, Z., Yeo, N., &amp; Yoshimura, K. (2024).
