The first of a series of global maps of above ground biomass was released at COP25 in Madrid. The new map uses optical, lidar and radar data acquired in 2017 and 2018 from multiple Earth observation satellites, and is the first to integrate multiple acquisitions from the Copernicus Sentinel-1 mission and Japan’s ALOS-2 mission. Introducing data from these satellite sensors improves the accuracy of forest biomass detection across different biomes, and is a significant advance on the 2010 map previously generated by the GlobBiomass project.

The global AGB map is freely available from the Climate Change Initiative’s Open Data Portal. Further information can be found in the Climate Research Data Package (v1.0), Product User Guide (v1.0) and Product Validation & Intercompaison Report (v1.1).
