Melissa supports data assimilation at scale with two variants, one for EnkF like algorithms and one for Particle Filters algorithms. Here is the repo: https://gitlab.inria.fr/melissa/melissa-da.
We have two associated papers:
- An elastic framework for ensemble-based large-scale data assimilation
- A Framework for Large Scale Particle Filters Validated with Data Assimilation for Weather Simulation.
