Tender description

ECMWF as the Entrusted Entity for the Copernicus Climate Change Service (C3S) has issued and/or will issue ITTs for providing access to climate projections at global and regional level, developing multi-model products focussed on projected values of Essential Climate Variables (ECVs), assessing the potential benefit of improving specific aspects in the production of climate projections (e.g. with respect to the standards specified in international inter-comparison projects), and filling recognized gaps in the production of regional projections. A common goal across the C3S activities is a comprehensive assessment of the projection uncertainties, with reliable estimations of the roles played by different emission scenarios, global and regional model formulation, and internal climate variability. This particular ITT will be dedicated to the provision of regional projections produced with regional climate models (RCM) for different emission scenarios, to be developed as a part of the Service. In the initial stages, C3S activities will be mainly based on simulations already available and produced under the CORDEX subprojects covering the European domain and adjacent regions (particularly EURO-CORDEX and MED-CORDEX). Minimum standards will be required in order to allow the production of reliable probabilistic multi-model products, and to assess the capability of individual models in simulating relevant aspects of the climate system. At the same time, actions will be promoted to provide support to a new generation of RCM simulations which are expected to contribute to the next IPPC Assessment Report. Such actions include the storage and access of boundary conditions derived from global simulations through the C3S Climate Data Store (CDS), and support towards the definition and production of an appropriate matrix of RCM-GCM-scenario combinations. Framework agreements of up to 48 months will be issued in 2 Lots: — Lot 1: Access to CORDEX simulations for the European domain. — Lot 2: Definition and generation of a ‘3-D matrix’ of RCM projections.
