Data & code repository for A pseudoproxy emulation of the PAGES 2k database using a hierarchy of proxy system models
This repository includes the pseudoPAGES2k dataset described in the paper entitled A pseudoproxy emulation of the PAGES 2k database using a hierarchy of proxy system models 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/
The pseudoPAGES2k dataset includes multiple versions with various settings. Please click the links below to download a specific version.
