NASA will take unique 3D snapshots of the Earth's forests from the International Space Station

16/12/2014

A laser-based instrument being developed for the International Space Station will provide a unique 3-D view of Earth’s forests, helping to fill in missing information about their role in the carbon cycle.

Called the Global Ecosystem Dynamics Investigation (GEDI) lidar, the instrument will be the first to systematically probe the depths of the forests from space. The system is one of two instrument proposals recently selected for NASA’s Earth Venture Instrument program and is being led by the University of Maryland, College Park. The instrument will be built at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

The Global Ecosystem Dynamics Investigation lidar will reveal the 3-D architecture of forests, as depicted in this artist’s concept. The unprecedented detail of these measurements will provide crucial information about the impact that trees have on the amount of carbon in the atmosphere.
