In contrast, the method used by Miller and his colleagues, called a top - down method, uses measurements of methane in the atmosphere, taken from a national network of greenhouse gas monitoring stations and aircraft measurements conducted by the National Oceanic and Atmospheric Administration and the Department of Energy.

For example, several studies use innovative aerial measurements taken by specially instrumented aircraft equipped with methane sensors.

And that's what I mean by measurement and sensing; that's a smart aircraft that can tell you where there might be problems and where you have to do maintenance instead of doing what they have to do at the moment, which is pull apart the aircraft in order to be able to determine if it needs maintenance.

This is a well - established methodology, pushed to constrain US anthropogenic emissions by including measurements from aircraft and communications towers in addition to the ever - invaluable NOAA flask sample network, and incorporating socioeconomic and industrial data.
