Comparison of CO2 and H2O fluxes over grassland vegetations measured by the eddy-covariance technique and by open system chamber

Original language description

Measurements of CO2 fluxes were carried out using two different techniques -eddy covariance (EC) and open system gas exchange chamber (OC) during two years period at three different grassland sites. OC measurements were made during fourteen measurementscampaigns. We found good agreements between the OC and EC CO2 flux values (n=63, r2=0.5323, OC FCO2=-0.6408+0.9508EC). The OC FH2O values were consistently lower that those measured by the EC technique, probably caused by the air stream difference insideand outside the chamber. Adjusting flow rate within the chamber to the natural conditions would be necessary in future OC measurements. In comparison with EC, the OC proved to be a good tool for gas exchange measurements in grassland ecosystems.
