Atmospheric Satellite Observations: Variation Assimilation and Quality Assurance provides an invaluable reference for satellite data assimilation. Topics covered include linear algebra, frequently used statistical methods, the interpolation role of function fitting, filtering when dealing with real observations, minimization in data assimilation systems, 3D-Var and the inverse problem it solves, 4D-Var and adjoint techniques, and much more. The book concludes by showing together satellite observation of hurricanes.Contains mathematical concepts from several branches of study, including calculus, linear algebra, probability theory, functional analysis, and minimizationIllustrates quality assurance for satellite observations using real data examplesIncludes a dedicated chapter on how different satellite instruments see hurricanesReviews theory, system development, and the numerical experiments of three- and four-dimensional variational data assimilation (3D-Var/4D-Var)
