## Summary

The Department for Science, Innovation & Technology has awarded a contract under the title "Continued UK Contribution to the MicroCarb Mission – CO₂ Retrieval Algorithm Development and Programme Support." This procurement process falls under the central government category with a direct procurement method due to technical reasons, specifically targeting services related to atmospheric CO₂ measurements. Located in London, the procurement stage is complete, with the award confirmed on 14th July 2026. The project is set to commence on 10th August 2026 and end on 31st March 2027, with potential annual extensions until 2030, depending on mission requirements and funding. The total award value stands at £694,500, with NPL Management Limited being the selected supplier for their expertise and established role in the MicroCarb mission.

This contract presents significant opportunities for businesses specialising in algorithm development, data processing, and technical programme support within the aerospace and IT services categories. The focus on CO₂ retrieval algorithm development and programme support is particularly suitable for companies that can deliver high-precision software solutions and technical validation services. Whilst the procurement was conducted directly due to the need for continuity and technical embedding, the extension options over several years suggest potential future opportunities for businesses capable of integrating into the MicroCarb mission framework. Companies with capabilities to innovate in data handling and validation would be well-positioned to benefit from similar contracts in the evolving field of climate and space research.

## Notice

The MicroCarb mission is a Centre National d'Etudes Spatiales (CNES) led satellite mission designed to deliver high-precision measurements of atmospheric carbon dioxide (CO2). The United Kingdom contributes to the mission through scientific, technical and validation activities coordinated by UK Space Agency (UKSA) and delivered via UK partners. This contract covers the continuation of activities required to support the UK contribution for the remainder of FY 2026-27, with a particular focus on continued CO2 retrieval algorithm development, post-launch data exploitation, and ongoing programme-level technical engagement within the MicroCarb mission framework. The services under this contract will continue the development and application of CO2 retrieval algorithms, preparation for the ingestion and processing of MicroCarb data products provided by CNES, and coordination of UK expertise through continued participation in the MicroCarb Advisory Group (MAG). The work builds upon progress delivered to date in providing mission-specific technical support, including adaptation of NASA-developed retrieval frameworks and preparatory activities supporting the transition of MicroCarb towards an operational data exploitation phase. Activities will place increased emphasis on algorithm robustness, data handling capability, validation readiness and sustained mission engagement. Activities under this contract would include: CO2 Retrieval Algorithm Development and Assessment - Incorporation of prior information modules (ABO2 and GASBAG) and a meteorological pre-processor (GEOS-IT) into the CO2 retrieval pipeline; adaptation of existing NASA-developed software to operate with synthetic MicroCarb data for the standard three spectral bands; Development of capability to ingest and utilise the fourth MicroCarb spectral band (1.27 um) and assessment of its performance; Assessment of preliminary MicroCarb Level 2 retrieval performance, including preparation for comparison with CNES retrieval products. MicroCarb Advisory Group and Programme Support - Representation of UKSA/DSIT within the MicroCarb Advisory Group (MAG); Liaison with UK and French partners, including CNES; Provision of technical and programme-level updates and reporting; and submission of a summary report of activities undertaken.

### Procurement Information

The Authority considers that the required services can be supplied only by National Physical Laboratory (NPL) due to technical reasons, and that no reasonable alternative or substitute exists. NPL's role is technically embedded over time within the MicroCarb mission through established responsibilities for CO2 retrieval development, calibration and validation readiness, and formal participation in mission governance structures overseen by CNES as technical authority. The UKSA Office of the Chief Engineer, in consultation with stakeholders in CNES, has considered whether alternative organisations could reasonably deliver this scope through competition; however, due to mission-embedded knowledge, CNES technical accreditation requirements, and the need for continuity of algorithm validation and quality assurance activities, no reasonable alternative supplier could deliver the requirement within acceptable technical or programme risk.
