Constrained random diffeomorphisms for data assimilation

Abstract

We show that both SALT and LU equations can be recovered using a prescribed definition of a random diffeomorphism used to perturb the physical space. However, compared with SALT and LU settings, the proposed perturbation scheme does not directly rely on a particular physics. Hence, the random mapping is more flexible and can be applied to any PDE.
