State-dependent Preconditioning for Data Assimilation

Résumé

Variational Data Assimilation requires the optimization of a high-dimensional function. This is usually done by linearizing the problem, and then inverting the Gauss-Newton matrix. ¿ Can we build a state-dependent preconditioner which would help for the inversion of the linear system ?
