Biomass represents an innovative leap in Earth observation. As the seventh mission in ESA’s Earth Explorer Programme, it breaks new ground as the first satellite to deliver P-band Synthetic Aperture Radar (SAR) measurements from space. By utilizing a fully polarimetric system and collecting tomographic data, the mission provides a unique capability to penetrate dense forest canopies and map 3D vegetation structures. This advanced SAR configuration offers an unprecedented dataset for quantifying global forest biomass and refining models of the terrestrial carbon cycle.

Beyond forestry, its long-wavelength signals provide new insights into subsurface geology in deserts, the internal structure of ice sheets, and the dynamics of the ocean and ionosphere.

This hackathon offers an exciting opportunity for Biomass pros and newcomers alike to collaborate, share insights, and help improve the Multi-Mission Algorithm and Analysis Platform (MAAP) and the BioPAL open-source processor suite during a hands-on week of coding.

The main objectives of the hackathon are to:

• Foster Global Collaboration: The event encourages open data sharing and collaborative workflows. It provides a unique space for experts to work together on Biomass data analysis, cross-compare findings with other missions or in-situ data, and brainstorm novel use cases for the mission’s output.
• Evolve Biomass Processors: A primary goal is the continuous improvement of the mission’s processing chains. Participants will help refine and evolve algorithms, ensuring that the processors remain cutting-edge and capable of delivering the highest quality geophysical products.
• Enhance Data Accessibility: We aim to make high-quality data resources seamless and intuitive to use. By streamlining access, we ensure researchers can dedicate their energy to scientific discovery rather than technical troubleshooting. The hackathon will serve as a vital feedback loop to further optimize the user experience on the MAAP.
• Innovate Analysis and Visualization Tools: Using the mission’s Collaborative Environment on the ESA MAAP, participants will explore and develop innovative tools. The focus is on creating sophisticated methods to analyze and visualize complex datasets, making Biomass insights more accessible and impactful for the global scientific community.

The following is a list of preliminary topics of interest for the hackathon. Participants can suggest additional topics or express interest in one or more of the preliminary ones. During the event, participants will split into groups and work together on a selection of topics.

• A 5-day, in-person hackathon, 12–16 October 2026, at ESOC (ESA’s Mission Control Centre) in Darmstadt (near Frankfurt), Germany.
• It is open to Master, PhD and postgraduate researchers interested in the Biomass mission and its applications.
• Python familiarity is required for the hands-on coding work.
• Working language: English.
• No participation fee. Participation is limited to 35 attendees.
