studying carbon from space .
There's a new force on the scene for NASA scientists studying carbon from space -- the Global Ecosystem Dynamics Investigation, GEDI. The instrument will launch to the International Space Station, where it will travel over Earth's light and dark sides and measure carbon stored in forests.
GEDI works by bouncing 8 laser beams off Earth's surface, and timing how long it takes them to strike back to the spacecraft. Over time, GEDI will help scientists build a 3D map of forest canopy and structure around the planet, to calculate how much carbon is stored in vegetation. Carbon is a greenhouse gas, so understanding how forests store carbon is important to forecasting and mitigating climate change.
NASA Goddard built the instrument in collaboration with the University of Maryland. From Endor to Earth, GEDI will improve our understanding of how carbon is stored in trees.
