New 3D Methane Models Help NASA to Track Global Trends

A three-dimensional portrait of methane concentrations around the world is helping researchers to understand the complex gas, which constitutes the second largest contributor to greenhouse gas (GHG) warming after carbon dioxide. Methane is an important GHG that is emitted during the production and transport of coal, natural gas and oil as well from agricultural practices like rice cultivation and the raising of livestock, according to the U.S. Environmental Protection Agency (EPA). Once lofted into the atmosphere, high-altitude winds can transport methane far beyond its source, disproportionately impacting communities around the world. "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.
