This repository includes the pseudoPAGES2k dataset described in the paper published in Scientific Data: Zhu, F., Emile-Geay, J., Anchukaitis, K.J. et al. A pseudoproxy emulation of the PAGES 2k database using a hierarchy of proxy system models. Sci Data 10, 624 (2023). https://doi.org/10.1038/s41597-023-02489-1 along with the Jupyter notebooks illustrating the usage of the dataset. The reference climate input used to generate the pseudoproxies is from the isotope-enabled Community Earth System Model (iCESM) last millennium plus historical simulations (Brady et al., 2019), and the post-processed files can be downloaded here: https://atmos.washington.edu/~rtardif/LMR/prior/
