Error Propagation in Variational Data Assimilation

Abstract : The approach of Data Assimilation via Optimal Control Methods leads to a dynamical system: the Optimality System in which all the available information is gathered. The propagation of uncertainties must be carried out not just from the model but from the O.S. I introduced a second adjoint from where the evaluation of the dynamics of uncertainties are studied.
