Untangling methane sources

Cutting-edge instrumentation, techniques can affordably separate methane emission sources

With natural gas booming across the Front Range, drilling rigs may operate within feet from cattle farms. That shared land use can confound attempts to understand trends in methane, a greenhouse gas and air pollutant because the gases emitted from these different sources blend together.

To untangle them, a team led by the Cooperative Institute for Research in Environmental Sciences (CIRES), with support from the National Center for Atmospheric Research (NCAR) has created a new, cost-effective technique to efficiently measure column methane and a cocktail of associated chemicals in the atmosphere, and to create a kind of chemical identification tag for methane sources.

"This research takes a novel next step to more directly determine the sources of methane on a small or regional scale like the Front Range," said NCAR scientist James Hannigan, a co-author of the study. "It provides a blueprint for more accurate monitoring of emissions of this important greenhouse gas."
