Four-dimensional Variational Assimilation

Four-Dimensional Variational Assimilation is a data assimilation method that belongs to the class of variational techniques and specifically integrates observational data across a continuous time window by minimizing a cost function that measures the misfit between the model trajectory and observations in both space and time.
