An orbital NASA instrument designed mainly to advance studies of airborne dust and its effects on climate change has proven adept at another key Earth science function – detecting large, worldwide emissions of methane, a potent greenhouse gas. The device, called an imaging spectrometer, has identified more than 50 methane “super-emitters” in Central Asia, the Middle East and the Southwestern United States since it was … Continue reading NASA instrument detects dozens of methane super-emitters from space
