C3S2_411 Lot 1 Operational Copernicus Climate Change Water Service

ECMWF, as the Entrusted Entity for the Copernicus Climate Change Service (C3S), invites tenders 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. Data will be delivered through the CDS and will offer a user-friendly web interface complete with links to data, applications, and demonstrations. 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).

For each Lot, ECMWF intends to award a single Framework Agreement for a period of 36 months, which shall be implemented via Service Contracts expected to commence in Q4 2024. Tenderers are invited to submit their Tenders for any one of the Lots, a combination of two, or for all three Lots.

Lot 1: The historical to seasonal forecast multi-model component of the C3S operational water service

The vision of Lot 1 is to provide a state-of-the-art operational multi-model seasonal hydrological forecasting service at the European and global scale to a wide range of users in the water sector. Lot 1 will develop a flexible framework to bring diverse types of hydrological models together in a consistent way so that outputs can be compared to understand past, current, and future changes in hydrological variables.
