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.
The location of the explosion is marked by a black dot in the image, and shows the methane emissions before and after the blowout. The black arrow indicates the wind direction and the direction of the methane plume.
Claus Zehner, ESA’s Copernicus Sentinel-5P mission manager, comments, “These Sentinel-5P measurements show that satellites can measure the concentrations of greenhouse gases emitted by a point source. The satellite’s capabilities will be further exploited with the upcoming Copernicus Carbon Dioxide Monitoring mission.”
