Offered to

PHYSICAL OCEANOGRAPHY

Course Objective

The class aims to provide fundemental knowledge and techniques to combine ocean observations and models to predict future state of the ocean. An advanced data assimilation methods that are considered useful in oceanography will be will be reviewed. The class will cover from basic and simple methods in data asimilation to more advanced methos like Kalman filters.

Learning Outcomes of the Course Unit

1   Understanding of the fundamental objectives of data assimilation in ocean modelling
2   Gain knowledge on the theory of data assimilation
3   Understanding of the basic ideas of 4D-var and Kalman-filter
4   to learn asiimilation of the data into models
5   to be able to use basic tools in data asimilation for real case studies
