Atmospheric Science Day 2024

CLIMACT co-organises, together with the Expertise Center for Climate Extremes (ECCE) and a small organising team led by Tom Beucler and Hendrik Huwald, the third edition of the Atmospheric Science Day, that will take place on Friday 1 November 2024, from 8:45 to 17:00.

This event aims to bring together the UNIL and EPFL communities involved in the atmospheric sciences, which are essential to forecasting and understanding climate change, with a particular focus on early-career researchers.
