This NSF project aims to establish a premium water isotope research station with high quality, frequent and uninterrupted atmospheric vapor isotope (2H and 18O) measurements to investigate vapor isotope fractionation and its applications on ecosystem-atmosphere water and CO2 exchange. The proposed research builds upon current understanding of water vapor isotopic fractionation under the influence of vegetation-atmosphere interaction. This project will evaluate a number of critical assumptions in hydrospheric isotope models, identify key fractionation processes, and develop mechanistic algorithms to address caveats that mask the potential of hydrogen and oxygen isotope tracers in hydrological and carbon cycle research. This research is conducted at an AmeriFlux site Wind River Canopy Crane in southern Washington.
