A variational continuous assimilation technique

Abstract

A variational assimilation technique is presented which continuously adjusts a model solution by introducing a correction term to the model equations. The technique is essentially a modification of the adjoint technique. The Variational Continuous Assimilation (VCA) technique optimizes the correction to the model equations rather than the initial conditions as is done in the adjoint technique. Application of this correction during a forecast produced substantially improved simulations. -from Author
