“When fire burns into permafrost, there are catastrophic changes to the land surface that are different from a fire burning here in California, for example,” said Clayton Elder, co-author and scientist at NASA’s Jet Propulsion Laboratory in Southern California, which developed AVIRIS-NG. “It’s changing something that was frozen to thawed, and that has a cascading impact on that ecosystem long after the fire.”
