Methane is a potent greenhouse gas emitted from a wide range of human activities including oil and gas production, coal mining, waste management, and agriculture. Satellites have unique capabilities to quantify and attribute methane emissions worldwide. In this talk, I will discuss recent advances in satellite remote sensing of methane emissions, including targeted observation of individual point sources, global mapping of large emitters with land-imaging satellites, real-time tracking of extreme releases from geostationary orbit, and continuous monitoring of total regional emissions from oil and gas fields.
