Flux tower

Carbon dioxide, water vapour and energy fluxes are measured continuosly with the eddy covariance techique. The fluxes are measured from the tower above the canopy. CO2 / H2O concentration is equal to the net exchange of CO2 / H2O between the ecosystem and the atmosphere. The fluxes are averaged over 30-min time periods and provide a continuous time-series.

The eddy covariance technique integrates the fluxes originating from a large area, thus representing CO2 dynamics at the ecosystem scale. The measured fluxes represent an average exchange rate from an area upwind from the flux tower. The source area varies continuously with atmospheric stability, wind speed and direction.
