Study finds emissions occurring in Earth’s atmosphere, spotting infrared signals from carbon dioxide during an aurora similar to northern lights.
They used the Atmospheric Infrared Sounder instrument, which gathers infrared energy emitted from Earth's surface and atmosphere globally.
These annotations were confirmed by the simultaneous sounding of the atmosphere using Broadband Emission Radiometry measurements and the SuperMAG Electrojet index, the study states. Additionally, ASU explains that, while aurora formations may be commonly observed in the Earth’s atmosphere, those linked to carbon dioxide are rare and exist in small quantities.
Carbon dioxide molecules also exist in small quantities in the Earth's atmosphere at the edge of space.
