C3S2_411 Operational Copernicus Climate Change Water Service

ECMWF, as the Entrusted Entity for the Copernicus Climate Change Service (C3S), entered into a series of contracts for the establishment of a unique operational C3S water service as a core provider of European and global scale climate and hydrological information to assist decision-making for a diverse range of users in the water sector at seasonal and climate timescales. This service covers the provision of three contracts to produce timely, high-quality information for the water sector encompassing historical data, a seasonal forecasting component (Lot 1), a collection of climate projection outlooks (Lot 2) and a user-oriented service and interface (Lot 3). Its design is flexible, ensuring the provision of consistent climate inputs for hydrological modeling (supporting both hydrological science and downstream operations), alongside a suite of pre-computed hydrological variables (from a multi-model composition, with possibility to include AI-based models) and indicators (supporting e.g. policy and decision-makers).
