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 multi-annual Service Contract, expected to commence in Q3 2026.

ECMWF, as the Entrusted Entity for the Copernicus Climate Change Service (C3S), invites Tenders for the maintenance and extension of C3S windstorm and storm surge services. The requirements are split into two Lots: maintenance and extension of the Operational Windstorm Service (Lot 1), and maintenance and extension of operational storm surge products (Lot 2). For each Lot, ECMWF intends to award a single Framework Agreement for a period of maximum 28 months, which shall be implemented via a single multi-annual Service Contract expected to commence in Q3 2026. Tenderers are invited to submit their Tenders for either one or both Lots. Note that the expertise required for each Lot strongly differ. In cases where a Tenderer opts to submit Tenders for both Lots, it is mandatory that each Tender is presented as a separate submission, with its own set of documents, including but not limited to, technical proposals, pricing tables and any required supporting documents. Tenderers must ensure that the submissions for each Lot are independently viable and stand on their own merits. At the same time, Tenderers should indicate what synergies, including cost savings, can be achieved should more than one Lot be awarded to them.

ECMWF, as the Entrusted Entity for the Copernicus Atmosphere Monitoring Service (CAMS), invites tenders for provision of Development and provision of observation-based hot-spot emissions of CH4, NO2, and CO2 from existing satellites and the first CO2M mission. These services are for extending the monitoring of large point sources and hotspot emissions in CAMS to also include nitrogen oxides (NOx) and carbon dioxide (CO2) and prepare for the uptake of CO2M observations for CH4.

ECMWF, as the Entrusted Entity for the Copernicus Climate Change Service (C3S), invites Tenders for the maintenance and evolution of the European Climate Data Explorer (ECDE). ECMWF intends to award a single Framework Agreement for a period of maximum 24 months, which shall be implemented via a single multi-annual Service Contract expected to commence in Q4 2026.

ECMWF, as the Entrusted Entity for the Copernicus Climate Change Service (C3S), invites Tenders for the development of a statistical framework for event attribution. ECMWF intends to award a single Framework Agreement for a period of maximum 24 months, which shall be implemented via a single multi-annual Service Contract expected to commence in Q4 2026.

ECMWF, as the Entrusted Entity for the Copernicus Atmosphere Monitoring Service (CAMS), invites tenders for the provision of quantitative estimates of net surface fluxes of greenhouse gases, which are key drivers of the Earth's climate evolution.

ECMWF, as the European Commission’s entrusted Entity for operating Copernicus Climate Change Service (C3S) and Copernicus Atmosphere Monitoring Service (CAMS), invites tenders for services related to the Provision of user outreach, community engagement and domain expertise services in support of the Copernicus Energy and Health Hubs.

ECMWF, as the Entrusted Entity for the Copernicus Climate Change Service (C3S), invites Tenders aiming to expand the scope of climate information delivered in the Land and Ocean domains by incorporating products and services for additional Essential Climate Variables (ECVs) split into five distinct Lots, specifically for Sea Surface Salinity (Lot 1), Permafrost (Lot 2), Above-Ground Biomass (Lot 3), Surface Albedo (Lot 4), Leaf Area Index (LAI) and Fraction of Absorbed Photosynthetically Active Radiation (fAPAR) (Lot 5). The purpose of this Invitation to Tender (ITT) is the provision of operational services aimed at ensuring dependable access to high-quality, consistent, and globally homogeneous satellite climate data products via the Climate Data Store (CDS). The services shall include the following technical activities: (•) Operation and maintenance of processing systems to generate CDR / ICDR datasets (unless these operations are supported by other initiatives). (•) Implementation and/or improvement of operational production chain components as needed to achieve Full Operational Capacity. (•) Provision of access to datasets via the CDS. (•) Quality assurance and validation of the resulting datasets. (•) Provision of supporting documentation that describes the operational algorithms employed in dataset generation, outlines the results of quality assessments, and a user guide to assist users in the appropriate utilisation of the datasets. (•) Maintenance of metadata describing CDR datasets and their associated documentation. (•) Provision of user support services. (•) Contribution to the European State of the Climate, contingent upon the maturity and latency of the ECV data, the upcoming C3S climate dashboard, or an alternative form of support for climate intelligence. For each Lot, ECMWF intends to award a single Framework Agreement for a period of 30 months, which shall be implemented via a single Service Contract (unless multiple Lots are awarded to the same Tenderer) expected to commence in January 2026. Tenderers are invited to submit their Tenders for any one of the Lots, or any combination of multiple Lots (with each submission to be done separately). Participation in multiple Lots in a non-lead capacity (e.g. as a subcontractor or supporting entity) is also permitted. The evaluation of bids will be conducted per Lot.

ECMWF as the European Commission’s entrusted Entity for operating Copernicus Climate Change Service and Copernicus Atmosphere Monitoring Service, invites tenders to work with the ECMWF to : 1) Provide technical support for the operational management of the Data Stores Service (DSS) platform assuring its reliability and correct functioning. 2) Enhance the Data Stores Service (DSS) platform collaborating in the design, development, and implementation of software components.
