New 3D view of Methane Tracks Sources on Earth

NASA’s new three-dimensional portrait of methane, shows the world’s second-largest contributor to greenhouse warming, as it travels through the atmosphere.

Combining multiple data sets from emissions inventories and simulations of wetlands into a high-resolution computer model, researchers now have an additional tool for understanding this complex gas and its role in Earth’s carbon cycle, atmospheric composition and climate system.



The new data visualization builds a fuller picture of the diversity of methane sources on the ground as well as the behavior of the gas as it moves through the atmosphere.

“There’s an urgency in understanding where the sources are coming from so that we can be better prepared to mitigate methane emissions where there are opportunities to do so,” said research scientist Ben Poulter at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
