In this study, two classes of methods including statistical and variational data assimilation algorithms will be described. In statistical methods, the model state is updated sequentially based on the previous estimate. Variational methods, on the other hand, seek an estimation in space and time by minimizing a cost function. Both of these methods require estimates of background state which is the prior information of the system and its error covariances. In terms of linear and Gaussian…

The Ensemble Kalman Filter: theoretical formulation and practical implementation
A fairly extensive discussion is devoted to the use of time correlated model errors and the estimation of model bias, and an ensemble based optimal interpolation scheme is presented as a cost-effective approach which may serve as an alternative to the EnKF in some applications.
A Three-Dimensional Variational Data Assimilation System for MM5: Implementation and Initial Results
A limited-area three-dimensional variational data assimilation (3DVAR) system applicable to both synoptic and mesoscale numerical weather prediction is described, and the use of the software architecture of the Weather Research and Forecast model is used to permit efficient performance on distributed-memory platforms.
Data Assimilation: Methods, Algorithms, and Applications
This book provides a framework for, and insight into, the inverse problem nature of data assimilation, emphasizing “why” and not just “how”, and provides a comprehensive guide that is accessible to nonexperts.
