Paleoclimate Boundary Condition Datasets (paleo_data)

This directory provides a clean, organized catalog of paleoclimate and Pre-Industrial boundary condition NetCDF datasets outside the Git repositories. Existing files on /scratchbad are symlinked into structured subdirectories, and newly generated palegoESM-ready boundary condition files are written to palegoESM/.

Related directories & public repositories:

• Hugging Face Dataset Repository: https://huggingface.co/datasets/guidov/palegoESM-data (public mirror of palegoESM/ and the 10-minute ice_sheets_and_topo/ reconstructions).
• GitHub Repository (palegoESM): https://github.com/guidov/palegoESM (and Release v0.1.0-data).
