ICOS at EGU26

The EGU General Assembly 3-8 May 2026 brings together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary, and space sciences. The EGU aims to provide a forum where scientists can present their work and discuss their ideas with experts in all fields of geoscience. 

As is our tradition, the ICOS community and project partners are organising a wide range of sessions and presentations, see below the schedule for the week.
