Performance analysis for high-spatial resolution satellite for methane emissions

Methane is the second most important contributor to climate change, after CO2. But relative to CO2, sources are easier to detect from space, and easier to stop. With a time constant of about one decade, reduction of methane sources can slow down climate change. At present, only the larger sources can be detected from space. With satellites that observe with a higher spatial resolution, many more small sources can be located and quantified, leading to more sources being reduced.
