Numerical Weather Prediction Model Verification and Development

The 55th Contracting Squadron at Offutt Air Force Base, Nebraska, is conducting market research via a sources sought notice for a Firm Fixed Price Indefinite Delivery/Indefinite Quantity contract titled Numerical Weather Prediction Model Verification and Development. The Air Force Weather (AFW) requires a unified, authoritative software steward to provide advanced scientific, computational, and software engineering capabilities to sustain and advance its next-generation Numerical Weather Prediction enterprise. The primary objective is to manage core modeling and data assimilation baselines, specifically the Model for Prediction Across Scales (MPAS), the Joint Effort for Data assimilation Integration (JEDI), and the METplus Suite, to eliminate technical risks and integration costs associated with branched codebases. The government is seeking sources with demonstrated expertise in large scientific codebases using Python, Fortran, and C++, as well as experience in atmospheric modeling, data assimilation, and the development of verification and validation tools. Key requirements include the ability to ingest next-generation environmental observations and implement rigorous software assurance and cybersecurity practices, including the delivery of Software Bill of Materials (SBOM). The contractor must adhere to strict security protocols for Controlled Unclassified Information (CUI) and comply with R-DFARS 252.204-7000 regarding the disclosure of information. Performance will be measured through specific quality thresholds, requiring high acceptance rates for technical deliverables and the remediation of critical vulnerabilities via a Plan of Actions and Milestones (POAM). All questions regarding this sources sought notice must be submitted by November 6, 2026.
