Description
Alana Ayasse and co-authors report a 2024 study of how well air and space sensors catch methane leaks. Methane is a potent greenhouse gas, and satellites are fast becoming a main tool to find its sources. Mixing data from many sensors could sharpen the picture, but each sensor's detection odds must be known.
In August 2023, the team timed airborne surveys to overlap with passes of a NASA satellite instrument called EMIT. The shared views let them measure and verify the satellite's detection limits under good conditions. They also built a statistical model to judge whether a silent sensor means a source was truly off. That model helps correct averages for steady sources that sensors miss part of the time. The work supports joint use of airborne and satellite data.
