“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. Illustration from the book
