Short summary

This paper documents the improved model experiment, which is used to generate the most updated, comprehensive and detailed climate and hydrological projections for the national climate assessment report for Norway published in October 2025. The new bias-adjusted daily high-resolution climate and hydrological projections are openly accessible and will serve as a knowledge base for climate change adaptation to decision makers at various administrative levels in Norway.
