Data Assimilation cover

This book offers an in-depth exploration of data assimilation methods, presenting theoretical foundations and practical applications. Data Assimilation serves as a comprehensive guide for readers.

This comprehensive volume delves into various popular data assimilation methods, illustrating how they can be derived from a unified theoretical foundation. It highlights the distinctions and connections among these methods, as well as the properties that define them. Through numerous examples, the text provides a clear understanding of both traditional state estimation and parameter estimation in data assimilation.

Data Assimilation emphasizes a mathematical framework that transcends specific disciplines like oceanography or meteorology. Instead, it presents the derivations and methodologies applicable to any field where dynamics intersect with measurements. While the mathematics is accessible, readers should have a foundational knowledge of spatial statistics, Bayesian statistics, and calculus of variations. The book also offers an introduction to the mathematical techniques used, complete with detailed derivations that are easy to follow.

The focus on ensemble methods, particularly the ensemble Kalman filter and smoother, makes this book a valuable resource for understanding the derivation, implementation, and application of these techniques. This second edition introduces significant new material related to combined parameter and state estimation problems, as well as insights into the general properties of ensemble algorithms. Additionally, the updated chapters and new content on topics like spurious correlations and localization enhance the reader's experience and understanding of data assimilation practices.

From the reviews of the second edition:

“This is a well-written and interesting book addressed to students taking an introductory course in data assimilation and inverse methods … . The material is presented with detail, and calculations are easy to follow. Many figures help the reader to assess the results. Several discussions and comments are provided in each chapter. In this sense, it is written in a pedagogical way. … a reference book for researchers interested in the interpretation and implementation of advanced ensemble methods.”­­­ (Jesús Marín-Solano, Mathematical Reviews, Issue 2011 c)

“Data assimilation, as defined by Geir Evensen, refers to the computation of the conditional probability distribution function of the output of a numerical model describing a dynamical process, conditioned by observations. … the book is subdivided into seventeen chapters, which progressively introduce different aspects of data assimilation with Kalman filters. … The book primarily addresses researchers in the field of data assimilation, for whom it represents a basic reference text. The text is very carefully written and is intended to be self-contained.”­­­ (Hans Wackernagel, Mathematical Geosciences, Vol. 42, 2010)
