How? It’s all thanks to a special lab built by ecologist Greg Asner inside a twin-turboprop airplane. From a few thousand feet up, the Carnegie Airborne Observatory uses lasers, spectrometers and other instruments to build a detailed 3-D model of a forest, identify different species of vegetation and quantify carbon sequestration. It’s a lot quicker than tramping through the jungle and taking these measurements on foot.
A fun tidbit from the full story:
“On one occasion, he and his team mapped more than 6,500 square miles of the Colombian Amazon at night — about the size of Connecticut plus Rhode Island — flying with all their lights out to avoid being shot at by the FARC, the Colombian rebel force.”
