Uncertainties in the assessment of the isotopic composition of surface fluxes: A direct comparison of techniques using laser-based water vapor isotope analyzers

The isotopic composition of surface fluxes is a key environmental tracer currently estimated with a variety of methods, including: Keeling mixing models, the flux‐gradient technique, and eddy covariance. We present a direct inter‐comparison of these three methods used to estimate the isotopic ratio...
