“Dynamic Data Assimilation: A Least Squares Approach”

John M. Lewis, S. Lakshmivarahan, Sudarshan Dhall

ABSTRACT
This book develops the mathematical tools that are central to present-day data assimilation at operational weather prediction centers worldwide. It is enriched by "pencil and paper" exercises as well as those that make use of mathematical software packages such as MATLAB. Each of the 32 chapters ends with pointers to the literature and discussions of historical foundations of the subject. As stated by reviewers of the book: "...it essentially covers all that we know about state estimation for dynamically evolving systems — a grand effort on a much needed textbook. A treasure and wonderful resource for students."

 

 

 

Carl Friedrich Gauss is shown aside the trajectory of a planetoid (dashed line), as it moves around the sun and is observed from earth (black circle). Gauss's prediction of the path of the planetoid from only a few observations in conjunction with Kepler's Laws was the beginning of dynamic data assimilation 200 years ago.
