Methane may not be as abundant in the atmosphere as carbon dioxide, but with a global warming potential many times greater than carbon dioxide, monitoring and controlling industrial emissions of this potent gas is imperative to helping combat climate change. GHGSat is a New Space initiative that draws on Copernicus Sentinel-5P data for mapping methane hotspots – and its Claire satellite has now collected more than 60,000 methane measurements of industrial facilities around the world.

Copernicus Sentinel-5P’s role is to map a range of atmospheric gases around the globe every 24 hours. Its Tropomi spectrometer delivers data with a resolution as high as 7 km × 5.5 km for methane, but these data can’t be used to pinpoint specific facilities responsible for emissions. However, GHGSat’s demonstration satellite ‘Claire’ can, but it is helped with a bit of guidance from Sentinel-5P.
