NASA is working on a new instrument for the International Space Station that will create a 3-D map of the Earth’s forests, in order to measure the role of trees in scrubbing carbon from the atmosphere.
The new instrument will use lidar, a laser system for measuring distance between the space-based instrument and the surface. Called the Global Ecosystem Dynamics Investigation (GEDI) lidar, the system will be put together at NASA’s Goddard Space Flight Center in Greenbelt, Md.
