| Zusammenfassung |
| Lagrangian data offer a challenge to data assimilation as they are not expressed directly in terms of flow variables. On the other hand, they offer an opportunity as they live in a low dimensional space (physical space of 2 or 3 dimensions). The strong nonlinearity of Lagrangian dynamics demands new techniques and we introduce a smoother based on statistical sampling that works well with some of the key nonlinear effects in a fluid flow. |
