Oil extraction and other human activities are sources of atmospheric methane (), but, as Donald Wuebbles and Katherine Hayhoe have shown, so too are naturally occurring emissions, such as those from termite mounds. This biogenic is challenging to track given natural sources’ variability and spatial diffusion, but one promising approach is to use flux data from extant monitoring infrastructure as proxies for fluxes in unmonitored areas.

Sparkle Malone and colleagues examined the United States’ network of eddy covariance (EC) towers—the equipment used to measure fluxes—and found that the towers are concentrated in particular ecological regions while many other land-cover types are sparsely monitored or absent entirely. Because the placement of the existing sites does not represent the full range of conditions that drive biogenic emissions, they cautioned that flux values measured at current locations cannot be assumed to hold for the unmonitored areas they are meant to stand in for.
