WebAssimilation. Data assimilation is an analysis technique in which the observed information is accumulated into the model state by taking advantage of consistency constraints with …
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.
