Earth Observation is the newest addition to the suite of EGU open access journals, launched in January 2026. It aims to capture a gap in the publishing landscape for a high quality, not-for-profit, OA journal run by a learned society and edited by experts in their domain. Come and meet the editors and learn about the journal plans and opportunities to contribute.

Join us to celebrate the 25th anniversary of Atmospheric Chemistry and Physics (ACP). Since its launch in 2001, ACP has become a leading journal for research advancing our understanding of the state and behaviour of the atmosphere and climate.
As a pioneer of interactive open-access publishing, ACP introduced a transparent two-stage publication process with public peer review and discussion. This innovative approach has helped bring scientific discourse into the open and has played an important role in shaping modern scientific publishing.
At this milestone, we invite the ACP community - authors, reviewers, editors, and readers - to celebrate 25 years of scientific advances, open exchange, and community-driven publishing, and to look ahead to the future of atmospheric and climate research.
