Weak-constraint Variational Assimilation

Weak-Constraint Variational Assimilation is a variational data assimilation method that belongs to the class of four-dimensional variational (4D-Var) techniques, distinguished by its explicit allowance for model error through the introduction of a time-dependent, stochastic forcing term in the governing equations, thereby relaxing the strong assumption of perfect model dynamics.
