Short summary
Industrial facilities release carbon dioxide and nitrogen dioxide. The Twin Anthropogenic Greenhouse Gas Observers (TANGO) mission, launching in 2028, will monitor both gases from ten thousand facilities per year using two satellites. We studied whether combining both improves carbon dioxide emission estimates and reveals plume chemistry. While this produces cleaner carbon dioxide images, precision does not improve as noise is redistributed not eliminated. Their ratio captures how nitrogen oxide converts to nitrogen dioxide within plumes.
