Data treatment and corrections for estimating H<sub>2</sub>O and CO<sub>2</sub> isotope fluxes from high-frequency observations

Abstract CO 2 H 2 O. When applying this method at a field scale, an isotope flux (δ H 2 O and CO 2 δ δ H 2 O compared to the net ecosystem flux of H 2 O, while this was not true for CO 2 H 2 O isotopologues due to the isotopic memory effect. We discuss how such artefacts can be detected and how they impact flux partitioning. We argue that these effects are likely due to condensation of water on a cellulose filter in our inlet system. Furthermore, we show that these artefacts can be resolved using physically sound corrections for inlet delays and high-frequency loss. Only after such corrections and verifications are made can ecosystem-scale fluxes be partitioned using isotopic fluxes as constraints, which in turn allows for conceptual land–atmosphere exchange models to be validated.
