Teaching in the first semester, review in January
Schedule
Units courses prerequisite and corequisite
Prerequisite or corequisite units are presented within each program
Learning unit contents
* Purpose of data assimilation and inverse methods
* Expressing uncertainty
* Origin of model and observation errors
* Reminder of static concepts: random variable, expectation, error covariance
* Sequential assimilation methods (nudging, successive corrections, optimal interpolation, 3D-Var, Kalman filter, Kalman smoother)
* Non-Sequential assimilation (4D-Var, representer method)
Learning outcomes of the learning unit
* understand various data assimilation methods
* able to conceptually define state vector, observation operator, observation vector and error covariances for a given problem

Written report on application of a data assimilation method on a simple model
If you plan to use a Large Language Model (LLM, like ChatGPT, LLaMa, GitHub Copilot...), you should consult the lecturer beforehand if the use of LLMs is appropriate. In any case, parts of the report or computer code generated or rewritten (partially or completely) should be clearly marked in the report.
This provision does not apply to the use of translation tools and spell checkers.
It is the student's responsibility to ensure that the content of the report is accurate and is not plagiarism (including unintended plagiarism).
