Detecting the presence of methane, a potent greenhouse gas

The International Space Station in July, the science team has identified more than 50 “super-emitters” in Central Asia, the Middle East, and the Southwestern United States. Super-emitters are facilities, equipment, and other infrastructure, typically in the fossil-fuel, waste, or agriculture sectors, that emit methane at high rates.

“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,” said NASA Administrator Bill Nelson. “The International Space Station and NASA’s more than two dozen satellites and instruments in space have long been invaluable in determining changes to the Earth’s climate. EMIT is proving to be a critical tool in our toolbox to measure this potent greenhouse gas – and stop it at the source.”

Methane absorbs infrared light in a unique pattern – called a spectral fingerprint. NASA's EMIT imaging spectrometer can discern with high accuracy and precision. The instrument can also measure carbon dioxide.

The new observations stem from the broad coverage of the planet afforded by the space station’s orbit, as well as from EMIT’s ability to scan swaths of Earth’s surface dozens of miles wide while resolving areas as small as a soccer field.

“These results are exceptional, and they demonstrate the value of pairing global-scale perspective with the resolution required to identify methane point sources, down to the facility scale,” said David Thompson, EMIT’s instrument scientist and a senior research scientist at NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission. “It’s a unique capability that will raise the bar on efforts to attribute methane sources and mitigate emissions from human activities.”
