C3S2_520_bis Evaluation and Quality Control for Datasets in the Climate Data Store

ECMWF, as the Entrusted Entity for the Copernicus Climate Change Service (C3S), invites Tenders for the delivery and operation of Evaluation and Quality Control (EQC) activities for datasets in the Climate Data Store (CDS). The aim of the EQC activities is to ensure that CDS datasets are subject to consistent quality assurance, scientific quality assessment, and fitness-for-purpose guidance, supporting informed and responsible use of climate data across a wide range of application contexts. EQC outputs are expected to be authoritative, transparent, traceable, and maintained as part of the operational CDS service.

ECMWF intends to award a single Framework Agreement, with a maximum duration of 24 months, which shall be implemented via a single multiannual Service Contract, expected to commence in Q3 2026. Portal instructions: Some of the ITT documents are accessible under the ‘Attachments’ box at bottom right of this page.
