Abstract
The problem of estimating an Eulerian velocity field given particle trajectories is formulated as an optimal filtering problem. Under the idealistic assumption that the Eulerian velocity field is delta-correlated in time (Kraichnan model) the exact solution of the non-linear filtering problem is found. In a more realistic Markov model with finite correlation time an approximate solution is suggested and examined by Monte Carlo means.
