Land vegetation is a large carbon store and represents opportunities to sequester additional carbon. While many Earth Observation missions aim to estimate forest carbon from space, their calibration and validation is critical. Ultimately, trust in biomass maps requires accurate ground data. Supporting ground measurements and the people who make them is thus mission-critical for mapping and tracking Earth’s forest carbon. Building on decades of work from the global research community with a strong representation of partners from the Global South, the GEO-TREES initiative aims to fund high quality ground data from a global network of long-term forest inventories, and to make these data open access. DATA.GEO-TREES is the data portal of the GEO-TREES initiative. It includes above ground biomass and canopy height data based on plot inventories and on airborne laser scanning.
DATA.GEO-TREES was launched in 2023 as a follow-up of the Forest Observation System (FOS), created in 2016, a project led by Dmitry Schepaschenko (IIASA) and Jérôme Chave (Toulouse University). The original goal of the project was to store high-quality aboveground biomass data and make them openly available to users. The legacy data included in the FOS are still available below, but DATA.GEO-TREES is now the main data portal for the GEO-TREES initiative. For information about DATA.GEO-TREES please contact:
