Water Vapor Isotope Measurements of Boreal Forests

Picarro Water Vapor Isotope Analyzer

AKWIN is quantifying the real-time water isotopes of vapor using a new Picarro water vapor isotope analyzer as a means to understand how storm tracks, daily patterns of gas exchange and seasonal shifts in water sources effect this important greenhouse gas. Continuous, real-time measurements will facilitate our understanding of how pulse rainfall events alter the sources of water that are transferred from the biosphere to the atmosphere and will provide insight as to how plant ecophysiological phenology regulates water flux from boreal systems to the atmosphere.
