High-frequency monitoring of anomalous methane point sources with multispectral Sentinel-2 satellite observations
12 April 2021
Satellites can detect methane emissions by measuring sunlight reflected from the Earth's surface and atmosphere. Here the authors show that the European Space Agency's Sentinel-2 twin satellites can be used to monitor anomalously large methane point sources around the world, with global coverage every 2–5 days and 20 m spatial resolution. The authors demonstrate this previously unreported capability through high-frequency Sentinel-2 monitoring of two strong methane point sources in Algeria and Turkmenistan.
