Variational Data Assimilation

Variational Data Assimilation is a data assimilation method that belongs to the class of optimization-based techniques, distinguished by its formulation of the state estimation problem as a variational problem where an objective functional, measuring the discrepancy between observations and model predictions weighted by their uncertainties, is minimized to obtain the optimal initial conditions for a numerical model.
