The European Space Weather Week (ESWW) 2026 will be held in Florence, Italy from 2nd – 6th November in a hybrid format. The overarching theme for ESWW2026 is ‘Data-driven and physics-based cross-scale Space Weather and Space Climate’.

The ESWW conference is an excellent opportunity for people from all over the world to gather and discuss the most recent insights in Space Weather and Space Climate, and to address the emerging challenges and impacts. Science, observations, data exploitation, data standards and metadata, service development, operational models, engineering and industrial needs are all important aspects of the field that are addressed.

One of the strengths of ESWW is that participants can contribute significantly to its content through Parallel Sessions, Plenary Sessions and Topical Discussion Meetings (TDMs). The ESWW Programme Committee (PC) and the Local Organising Committee (LOC) for ESWW 2026 are pleased to announce the following Call for convening of Plenary, Parallel sessions, as well as Topical Discussion Meetings.

Closing date (plenary and parallel) – 20th March 2026
