From the European Space Agency:
The first of a series of global maps aimed at quantifying change in carbon stored as biomass across the world’s forests and shrublands has been released today by ESA’s Climate Change Initiative at COP25 – the United Nation Climate Change Conference currently taking place in Madrid.
As plants grow, they remove carbon dioxide from the atmosphere and store it as biomass. This is then released back to the atmosphere through processes such as deforestation, disturbance or wildfires. Assessing these dynamic changes is key to understanding the cycling of carbon and also for informing global climate models that help predict future change.
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 mission.
