7-11 Jan 2019 Grenoble (France)

Course description

This course is organized and funded by the Doctoral school for "Earth, Planetary and Environmental Sciences" of Grenoble Alpes University. It is given in English upon request at the beginning of the session.

It takes place from 7 to 11 January 2019 and is composed of 14 lectures of 1:30 and 1 numerical training session (3 hours), or 12 lectures with 2 training sessions (this is under study). The course starts at 1:30pm the first day and end at 12pm the last day.

The course is given by Eric Blayo (UGA, LJK), Emmanuel Cosme (UGA, IGE), and Arthur Vidard (INRIA, LJK).

Some lecture notes are available here. Some jupyter notebooks illustrating the Kalman filter and related topics can be found here, and we are currently fighting against our agendas to provide the equivalent for variational methods.
