Data assimilation using OpenPALM

This training course aims to teach how to develop data assimilation applications using the coupler OpenPALM. After introducing data assimilation, the participants learn to build step by step a data assimilation chain based on a simplified ocean model. Finally, different variational approaches are presented.

Target participants:
This training session is for engineers, physicists, computer scientists
and numerical analysts who wish to develop or use modular data
assimilation applications based on numerical models.

Prerequisites:
It is recommended to have taken the training session Code coupling
using OpenPALM or to be familiar with OpenPALM before attending
this training course.
