The article shows a graphic of what existing monitoring satellites can do compared to what these satellites will do. For comparison, NASA launched the Orbiting Carbon Observatory 2 [1] in 2014, and it can monitor a swath 10km wide. This announcement is about Sentinel-7 [2], and it will monitor a swath 240km wide. This huge increase in monitoring will significantly improve what it can monitor (eg, montly/annual trends in CO2 production)
edit: It will allow monitoring of all CO2 production sites every two or three days

- mturmon 7y agoThanks. One very important feature that simple in situ monitors don’t provide is total column CO2. That’s the average concentration from the ground up to the top of atmosphere. The satellites, and advanced ground measurements, get total column CO2 by observing the behavior of slices of the solar spectrum that are affected by CO2. Basically, the gas absorbs some wavelengths and re-emits in others.
