Methane can be detected by optical spectrometry. Since methane is not only a pollutant but also a very potent green house gas (30x stronger than CO2), efforts are made to map the sources from the air and space [0-2]. Edit: I found the FLIR camera shown in the video. It is made for gas emission analysis: https://www.flir.com/products/flir-g-series/ https://www.flir.com/products/flir-g-series/ [0]https://www.optica-opn.org/home/newsroom/2022/february/mapping_methane_with_spaceborne_spectrometry/ https://www.optica-opn.org/home/newsroom/2022/february/mappi...
