Methane ‘super-emitters’ on Earth spotted by space station experiment

A powerful eye in the sky is helping scientists spot “super-emitters” of methane, a greenhouse gas about 80 times more potent than carbon dioxide.

This observer is NASA’s Earth Surface Mineral Dust Source Investigation Instrument, or EMIT for short. EMIT has been map the chemical composition of dust in all desert regions of the Earth since its installation outside the international space station (ISS) in July, helping researchers understand how airborne dust affects the climate.
