Data assimilation with the Lorenz model

Warning message

The start date of this training opportunity has already passed

General information

The goal of the course is to provide a hands-on introduction to various data assimilation techniques using the Lorenz model. The course will combine lectures on the theory of data assimilation and the construction of the numerical code to implement the Lorenz model and various data assimilation methods (in particular, Newtonian Relaxation and Ensemble Kalman Filter).

Programme information: 

- Introduction to the Lorenz model. History and properties. Creation of a simulation of the Lorenz model using the Fortran language. The time evolution of the model will be calculated using a fourth-order Runge-Kutta method. Visualization of the solutions. Decorrelation scales and predictability limits.

- Direct Insertion and Newtonian Relaxation (nudging). Theory and history of their implementation. Creation of a twin-experiment setting. The output of the numerical simulation will be used to generate a set of noisy observations. Various sampling scenarios will be simulated. Next, the students will have to implement Direct Insertion and Nudging. Validation strategies to assess the behavior of the different assimilation experiments.

- Implementation of a Kalman Filter assimilation scheme. The theory of the Kalman Filter and its extension to non-linear models will be provided. Next, the students will have to implement, test and validate their data assimilation algorithm.
