Tender Details

The primary objective of this ITT is to advance the ocean data assimilation system at ECMWF to enhance the use of observational data and support the development of next-generation climate reanalyses. Specifically, it aims to establish a more reliable and statistically self-consistent multi-scale ocean Ensemble of Data Assimilation system. Key focus areas include improving ensemble generation techniques, developing anisotropic and multi-scale background error covariance models, enhancing and operationalisation of 4D-Var capabilities, and advancing modelling of correlated observation errors. The tender will also support the development of a capability to assimilate Level 2 Sea Surface Temperature observations. ECMWF intends to award a single Framework Agreement for a period of maximum 30 months, which shall be implemented via a single multi-annual Service Contract expected to commence in January 2026 and with an end date not later than 30 June 2028.
