The C3S National Collaboration Programme (NCP) enhances the uptake and application of C3S climate data across EU Member States and Copernicus countries. Initiated by ECMWF and endorsed by the European Commission, the NCP reflects the recognition that close collaboration with countries at the national level is crucial to ensuring the relevance and long-term impact of C3S.

The programme facilitates dialogues with national stakeholders, supports climate service development, and promotes transboundary coordination to address shared technical and geographical challenges. Through co-designed, funded actions, it empowers countries to access high-quality climate data and develop tailored tools supporting a climate-resilient society, aligning with European climate policy objectives and national priorities.
