Data assimilation concepts
WebThe aim of a data assimilation scheme is to use measured observations in combination with a dynamical system model to derive accurate estimates of the current and future states of the system. In… 19 Adjoint Methods in Data Assimilation for Estimating Model Error A. Griffith, N. Nichols Environmental Science 2000 Data assimilation is distinguished from other forms of machine learning, image analysis, and statistical methods in that it utilizes a dynamical model of the system being analyzed. Data assimilation initially developed in the field of numerical weather prediction. See more Data assimilation is a mathematical discipline that seeks to optimally combine theory (usually in the form of a numerical model) with observations. There may be a number of different goals sought – for example, to … See more One of the common mathematical philosophical perspectives is to view data assimilation as a Bayesian estimation problem. From this perspective, the analysis step is an … See more Monitoring water and energy transfers Data assimilation has been used, in the 1980s and 1990s, in several HAPEX (Hydrologic and … See more • Daley, R.
