Methane emissions, be it from industrial cattle farming or fossil gas extraction, are accountable for roughly 30 p.c of the Earth’s local weather change points. But regardless of the large quantities of methane emissions launched into the ambiance yearly, it’s typically troublesome to trace the pollutant—other than being invisible to the human eye and satellites’ multispectral near-infrared wavelength sensors, methane can be exhausting to evaluate resulting from spectral noise within the ambiance.
To assist sort out this fast disaster, Google and the Environmental Defense Fund are teaming up for a new mission with lofty targets. Announced in a new weblog put up earlier right now, MethaneSAT in a new, AI-enhanced satellite mission to higher observe and quantify the damaging emissions, with an goal to supply the information to researchers around the globe.
“MethaneSAT is highly sophisticated; it has a unique ability to monitor both high-emitting methane sources and small sources spread over a wide area,” Yael Maguire, Google’s VP and General Manager of Geo Developer & Sustainability, mentioned in a February 14 assertion.

To deal with such a large endeavor, the EDF developed new algorithmic software program with researchers on the Smithsonian Astrophysical Observatory andHarvard University’s School of Engineering and Applied Science and its Center for Astrophysics. Their new supercomputer-powered AI system can calculate methane emissions in particular places, and subsequently observe these pollution as they unfold within the ambiance.
MethaneSAT is scheduled to launch aboard a SpaceX Falcon 9 rocket in early March. Once deployed at an altitude of over 350 miles, the satellite will circle the Earth 15 occasions per day at roughly 1,660 mph. Aside from emission detection duties, Google and EDF intend to harness their AI packages to compile a worldwide map of oil and fuel infrastructure programs to hone in what features rank because the worst offenders. According to Google, this will operate very similar to how its AI packages interpret satellite imagery for Google Maps. Instead of street names, road indicators, and sidewalk markers, nevertheless, MethaneSAT will assist tag factors like oil storage containers.
“Once we have this complete infrastructure map, we can overlay the MethaneSAT data that shows where methane is coming from,” Maguire mentioned on Wednesday. “When the two maps are lined up, we can see how emissions correspond to specific infrastructure and obtain a far better understanding of the types of sources that generally contribute most to methane leaks.” Datasets like these might show useful to watchdogs and consultants trying to rein in oil and fuel emission places which will develop into extra liable to leaks.
All this much-needed data is meant to develop into obtainable later this yr via the official MethaneSAT web site, in addition to Google Earth Engine, the corporate’s open-source international environmental monitoring platform. In the very close to future, the new emissions information will be capable to mix alongside datasets regarding components like waterways, land cowl, and regional borders to higher assess the place we’re as a world group, and what must be executed with a view to stave off local weather change’s worst outcomes.
