NASA space laser reveals rainforest mystery
We know less about the rainforest canopy, where most of the world’s species live than we do about the surface of Mars or the bottom of the ocean. However, that is about to change thanks to GEDI—a laser aboard the International Space Station that has provided a detailed structure of the world’s rainforests for the first time. Christopher Doughty and researchers throughout the world are using the 3D map to understand the amounts of biomass and carbon forests store and how much they lose when disturbed—vital information for understanding Earth’s carbon cycle and how it is changing.
