A nudging-based data assimilation method: the Back and Forth Nudging (BFN) algorithm
This paper deals with a new data assimilation algorithm, called Back and Forth Nudging. The standard nudging technique consists in adding to the equations of the model a relaxation term that is supposed to force the observations to the model. The BFN algorithm consists in repeatedly performing forward and backward integrations of the model with relaxation (or nudging) terms, using opposite sign...
متن کاملThe ”Back and Forth Nudging” algorithm for oceanographic data assimilation
In this paper, we generalize the so-called “nudging” algorithm in order to identify the initial condition of a dynamical system from experimental observations. The standard nudging algorithm consists in adding to the state equations of a dynamical system a feedback term, which is proportional to the difference between the observation and its equivalent quantity computed by the resolution of the...
متن کاملBack and Forth Nudging Algorithm for Data Assimilation
Data assimilation consists in estimating the state of a system by combining via numerical methods two different sources of information: models and observations. Nudging can be seen as a relaxation method, by applying a Newtonian recall of the state value toward its direct observation. The Back and Forth Nudging algorithm consists in iteratively and alternately solving forward and backward in ti...
متن کامل[hal-00638468, v1] Back and forth nudging for quantum state estimation by continuous weak measurement
We propose to apply the Back and Forth Nudging (BFN) method used for geophysical data assimilations [1] to estimate the initial state of a quantum system. We consider a cloud of atoms interacting with a magnetic field while a single observable is being continuously measured over time using homodyne detection. The BFN method relies on designing an observer forward and backwards in time. The stat...
متن کاملThe Back and Forth Nudging algorithm for data assimilation problems: theoretical results on transport equations
English: In this paper, we consider the back and forth nudging algorithm that has been introduced for data assimilation purposes. It consists of iteratively and alternately solving forward and backward in time the model equation, with a feedback term to the observations. We consider the case of 1-dimensional transport equations, either viscous or inviscid, linear or not (Bürgers’ equation). Our...
