Using radically innovative radar technology, we can measure the three-dimensional structure of forests from space, and thus estimate their height and how much wood they contain (their biomass). The European Space Agency’s 7th Earth Explorer mission, BIOMASS, launching in 2022, will use this technology to map the biomass of the world’s forests at around 200 metres resolution, and over its 5-year lifetime measure the gains and losses in biomass. This information is crucial in understanding climate change, but is also invaluable for better managing forests, especially in the tropics where change is most dramatic and where information is most needed. Shaun Quegan is a professor at the University of Sheffield and a member of the National Centre for Earth Observation. For around 25 years, his research has been mainly concerned with using satellite data and ecosystem models to clarify the role of the land surface, and especially forests, in the Earth’s carbon cycle and climate. He is the proposer and Lead Scientist of the European Space Agency BIOMASS mission, launching in 2022, which will measure forest biomass, height and disturbance worldwide, and has been a member of several key high-level committees advising on climate and Earth Observation by satellites.
