Description
ECMWF, as the Entrusted Entity for the Copernicus Climate Change Service (C3S), invites tenders to develop an advanced LLM-based search and discovery service, to enhance user access to climate and environmental data from the C3S Climate Data Store (CDS). The service will enable natural language querying, intelligent data summarisation, and personalised recommendations to support a broader and more diverse user base, including non-experts. It will integrate with existing systems like the CDS Virtual Assistant (“Knowledge Duck”) and explore the use of generative AI for automated quality assessments of datasets.
