Methane leak visible from space
17 December 2019
Data from the Copernicus Sentinel-5P satellite revealed that an explosion in a natural gas well in Ohio in February 2018 released more than 50 000 tons of methane into the atmosphere. The blowout leaked more of this potent greenhouse gas in 20 days than the majority of many European nations do in a year from their oil and gas industries.
The findings were published in a study yesterday in the Proceedings of the National Academy of Sciences, and the study reveals the importance of using satellite data to detect and quantify pollutants such as methane. Data from the Copernicus Sentinel-5P's Tropomi instrument revealed that 120 tons of methane were emitted per hour due to the blowout.
