The European Space Agency's (ESA) BIOMASS mission is scheduled to release its first forest carbon maps following a progressive schedule, beginning in late 2025 and moving to full open access in early 2026. The mission is designed to provide critical data on forest structure and carbon storage, launching in April 2025.

• December 12, 2025: ESA will grant full access to initial Level-1a, L1b, L1c, and Level-2a (Phase E2) products. These early releases follow the transition to the tomographic Phase E2 on November 21, 2025, during which the satellite acquires a stack of seven images for each point in the mission's acquisition mask.
• January 26, 2026: The Biomass satellite is set to go fully "live" (full commissioning/open data push), with open access to a powerful new stream of data.
• 2026 and Beyond: Progressive releases of refined forest biomass and carbon maps will continue throughout 2026 and during its planned 5-year mission to improve understanding of the global carbon cycle

Key Data Features: P-band Radar: The satellite is the first to use P-band Synthetic Aperture Radar (SAR), allowing it to penetrate forest canopies to measure woody biomass (trunks, branches) rather than just the top of the canopy.
Capabilities: The mission tracks carbon absorption/release, supports deforestation monitoring, and measures forest floor topography and desert subsurface geology.
