The EarthCODE Hackathon will take place from 30 November – 4 December 2026 at ESA ESRIN, in Frascati, Italy. The event will provide an opportunity to bring the communities who are using EarthCODE tools and services as close as possible to the people who are building them.

The EarthCODE Hackathon will bring together Ocean, Carbon, and Polar scientists, experts in FAIR data and workflow engineering and open source developers to focus on the creation and enhancement of thematic, analysis ready data collections, built from scientific project outputs. These collections will integrate multiple geophysical variables, delivered in cloud optimised, interoperable formats, and made openly accessible through the EarthCODE Open Science Catalogue.

The overall objective of the EarthCODE Hackathon is to demonstrate and strengthen EarthCODE’s role as a federated environment for publishing, discovering, and using Earth system data. Specifically, the hackathon aims to:

• Demonstrate how EarthCODE services support the publication and reuse of scientific data from ESA Science Clusters
• Build and showcase thematic analysis ready data collections for different scientific domains
• Enable Science Cluster teams to create and manage their own data collections using EarthCODE tools and libraries
• Promote open access and visibility of high impact scientific datasets via dashboards and interactive viewers
• Foster collaboration between scientists and the open source developer community
• Contribute to the evolution of EarthCODE services and tools

Registration will open in September 2026
