Closed-Path Eddy-Covariance Systems

Campbell Scientific offers closed-path eddy-covariance systems for fluxes of CO₂, H₂O (latent heat), sensible heat, CH₄, N₂O, and CO₂ isotopes. These systems are an optimum solution for long-term, low-maintenance flux monitoring thanks to the features of automatic zero/span, low-power requirements, and the revolutionary vortex intake (U.S. Pat. No. 9,217,692), which reduces maintenance and improves H₂O frequency response compared to traditional closed-path systems. The systems are also designed to minimize spatial separation and better synchronize measurements, thereby reducing uncertainties in EC fluxes. Customization of systems to accommodate energy balance and other sensors may be possible; contact Campbell Scientific for more information.
