Carrying a novel P-band synthetic aperture radar, ESA’s Earth Explorer Biomass satellite mission is designed to deliver completely new information on forest height and above-ground forest biomass from space.
Forests play a crucial role in Earth’s carbon cycle by absorbing and storing large amounts of carbon from atmosphere – therefore helping to keep our planet cool. However, as swathes of forest continue to be cleared, carbon is being released back into the atmosphere and exacerbating climate change.
From 666 km above, the Biomass instrument will be able to ‘see’ through the leafy forest canopy and measure the height of the trees. This information will be used to work out how much biomass – a proxy for carbon – is being stored in forests. This will reduce the major uncertainties in calculations of carbon stocks and fluxes on land, including carbon fluxes associated with land-use change, forest degradation and forest regrowth.
