Abstract : A large number of satellites provide a significant amount of photographs of the earth. Attempt to perform Image Assimilation have been done using pseudo-observation techniques: they provide some apparent velocity fields, which are assimilated as classical Eulerian velocity observations. However these measurements are obtained by procedures that are decoupled with the system. Here, we suggest a more consistent approach where image sequences are directly incorporated into the Optimality System in a Variational Data assimilation framework.
