Textbook in PDF format

This book summarizes about 75 years of the authors’accumulated experience within the formulation, development, and practical use of advanceddata-assimilation methods. We realize that no available texts discuss the multitudeof data-assimilation methods and problems in a“unified”manner and with a unifiednotation. Thus, we believe this book will serve as an essential resource for anyoneworking or planning to work in data assimilation.We also believe this book is very suitable for an advanced course in dataassimilation. The mathematical level is modest, and we explain all derivations inquite some detail. Furthermore, the book connects and gives a nearly completeoverview and introduction to today’s most popular data-assimilation methods.
