The Kayrros Methane Watch uses data acquired by the Sentinel-5P satellite, which is part of the Copernicus network of satellites operated by the European Space Agency. Abnormal concentrations of methane are automatically detected by Kayrros proprietary algorithms, which apply meteorological models to determine source flow rate and location taking wind direction and other local factors into account. Methane hotspots are attributed to specific assets such as oil wells or gas compression stations. This is based on local information including flaring and venting data as well as the use of high-resolution images.
