A new Global Change Biology paper explains the nature of spectroscopic effects and proposes a concept to account for such effects in eddy covariance flux measurements of any gas including GHGs. Specifically, the paper focuses on narrow-band measurements of open-path, enclosed systems and temperature- or pressure-uncontrolled, closed-path systems.

Supplemental materials are critical to fully understanding how these devices work and how fluxes from these should be calculated and why. These supplemental materials are located here.
