This imply including wave model output as forcing for the particles, in addition to the NEMO surface currents. Lucy will provide advice on how to do this, required variables, etc.
OpenDrift could be more adequate to achieve this in a short time frame. This software is being explore.
On PARCELS a Stokes Drift kernel will need to be implemented. We are yet to find an existing one, otherwise it will need to be coded on Python.
