New Map of Global Forest Heights

Scientists have released a global map of forest canopy heights based on NASA data. “Although there are other local- and regional-scale forest canopy maps, the new map is the first that spans the entire globe based on one uniform method,” says the NASA press release. “The work — based on data collected by NASA’s ICESat, Terra, and Aqua satellites — should help scientists build an inventory of how much carbon the world’s forests store and how fast that carbon cycles through ecosystems and back into the atmosphere.”
