Abstract
As part of the controlled release experiments at the Ginninderra test site, an eddy covariance (EC) flux tower was installed. The aim was to determine whether EC was an effective technique for detecting, locating and quantifying CO2 emissions from a leak. The results of this study suggest that EC can be used for leak detection, but application of the technique for quantification exposes problems in the underlying assumptions when dealing with heterogeneous localised leakage systems. The EC tower identified elevated CO2 fluxes from the direction of the leak during the release experiment. The median background CO2 flux from the field was 0.63 ?mol/m2/s, while median leakage CO2 fluxes ranged from 4.57 - 9.11 ?mol/m2/s based on proximity of wind directions to the leak. Once the controlled release stopped, CO2 fluxes from the leak direction quickly returned to background levels.
