C3S2_601_bis Advancing an Ensemble-Based, Multi-Scale Ocean Data Assimilation System for Climate Applications

Description du marché

This contract builds on developments carried out in previous C3S contracts (C3S_321b and C3S2_601) to enable an ensemble of data assimilations (EDA) for ocean reanalysis. The main objective of the Framework Agreement is to continue this development of the ocean data assimilation (DA) methodology to improve the use of observations and to develop the next generations of climate reanalyses. The focus areas of the developments are to improve the ocean EDA scheme so that it will produce a more reliable ensemble and extend it to sea-ice variables, to improve the representation of multiple scales in the DA, to continue to implement 4D-Var, and to improve the use of surface observations.
