Update: The final program is now available. Online registration is still open: https://indico3-jsc.fz-juelich.de/event/113/ (click 'Register Now', then you can select in person or online; online participants will receive a Zoom link in due course). To allow also participants from non-European regions to participate in the workshop, recordings of most sessions and talks will be made available to registered participants.

The last year has seen tremendous progress on large scale machine learning for numerical weather prediction. In the workshop we will take stock of the developments and discuss possible next steps and open research frontiers. For this, the workshop will bring together researchers from industry, modeling centers and academia and provide a forum for detailed discussions on the subject.

The workshop will be a mixture of talks and discussions to allow for a free exchange of ideas and help propel the field forward. Topics include:


Date and time: Faculty Club, University of Bonn; 4 September 2023, 9:30 - 5 September 2023, 18:00

Organizers: Martin Schultz (Jülich Supercomputing Center), Matthew Chantry (ECWMF), Christian Lessig (ECMWF), Jürgen Gall (University of Bonn),

We gratefully acknowledge support by ECMWF, the TRA Modelling at the University of Bonn, and the ERC Advanced Grant IntelliAQ.

Bonn has a variety of hotels at various price points. One with a good money/value ratio and very close to the workshop location is Motel One Beethoven. We recommend to book early since Bonn has many business travelers and hotels tend to become booked out and/or expensive.
