NASA’s EMIT instrument has found more than 50 methane super emitters in its first few months of operation—and that’s not even its main job
A powerful eye in the sky is helping scientists spy “super-emitters” of methane, a greenhouse gas about 80 times more potent than carbon dioxide.
“Reining in methane emissions is key to limiting global warming. This exciting new development will not only help researchers better pinpoint where methane leaks are coming from, but also provide insight on how they can be addressed—quickly,” NASA Administrator Bill Nelson said in a statement. “It turns out that methane also has a spectral signature in the same wavelength range, and that’s what has allowed us to be sensitive to methane,” EMIT principal investigator Robert Green, of NASA’s Jet Propulsion Laboratory in Southern California, said during a press conference on Tuesday afternoon.
That’s comparable to the peak rates of the Aliso Canyon leak, one of the largest methane releases in U.S. history.
