SkyTruth’s flaring maps show satellite detections of natural gas flaring across the entire planet.
Where does the data come from?
The data for this map was originally made available by NOAA’s Earth Observation Group. As of 15 October 2019, the data is now freely-available from Earth Observation Group (EOG), Payne Inst. for Public Policy, Colorado School of Mines.
How does flaring volume get estimated?
The Earth Observation Group have authored the following papers for those interested in the VIIRS instrument and how the flare volume is calculated.

How does the map data get processed?
What are the applications/uses for this map?
Applications for this map include:
Verified on the ground by a team we sent out North Dakota’s Bakken Shale and further cross-referenced against aerial and satellite imagery of other flaring hotspots such as Russia, Africa, and the Middle East, this map is updated daily to show the frequency of infrared detections hot enough to be gas flares.
I’m not seeing a flaring detection I expected to see. Why not?
If you don’t see a flaring detection you expected to see, it may be because of the ways that we process and present the flaring data. Some flares don’t burn hot enough to be included in our dataset, they may not have been burning when the satellite passed overhead, the flare may not be frequent enough to make it past the 3 detection threshold, heavy clouds have obscured the flare from the sensor, etc.
Over the 162 years since the world’s first commercial oil well was drilled in Pennsylvania, a vast network of oil and gas wells, pipelines, pumping stations, storage tanks, refineries, and distribution lines has been built. And this network -- including the modern pieces -- is riddled with leaks. That’s a big problem, because methane in the air absorbs heat from the sun, warming up our atmosphere.
We're always glad to have conservation-minded groups and individuals use our flaring maps, but we would like to correct some errors in how our data was interpreted in two recent articles in the Stabroek News concerning natural gas flaring from an ExxonMobil-owned vessel, the Liza Destiny, anchored off the coast of Guyana.
Three women shared their stories with a group of journalists and others attending the Society of Environmental Journalists 2019 meeting in Fort Collins, Colorado last month. Fort Collins sits right next to Weld County – the most prolific county in Colorado for oil and gas production and among the most prolific in the entire United States. There, hydraulic fracturing (mostly for oil) has boomed, along with a population surge that is gobbling up farmland and converting open space into subdivisions. Often, these two very different types of development occur side-by-side.
