PINZ (XGBoost) monthly 5km precipitation isotope predictions for New Zealand

This is the model output for the precipitation isotope model 'PINZ', which provides d2H and d18O predictions at 5km spatial resolution and monthly timestep across New Zealand. The date range for the model output is 1997-2025. For code and available underlying data, see the GitHub repository https://github.com/BruceDudley/Precipitation_isotopes_NZ As of 2 June 2026 the manuscript describing database collation for training data for this model is in review in Journal of the Royal Society of New Zealand (Dudley et al. 2026).
