EC-Earth General Assembly 2022

The EC-Earth General Assembly will be held hybrid during Oct. 11 – 13, 2022. The theme of the EC-Earth GA will be on the development of next generation of Earth System models and EC-Earth4. We will review the new science and technology in the Earth system modelling; revisit and report science outcome of, and lessons learned from EC-Earth3; and discuss the progress in EC-Earth4 development.

The logo of EC-Earth with different spaces for the different parts that goes into the model. Logo.

We invite presentations from the community that contribute to the themes of the meeting, as well as from studies using the EC-Earth model in various configurations or relevant to EC-Earth model development. As last year, we also welcome short presentations (2-slides) that inform the community research ideas and new results.

Venue: stora hörsalen, Pufendorfinstitute, Biskopsgatan 3 Lund
