The heat and mass exchange measurement techniques are commonly used for environmental studies. Globally we observe rapid increase of greenhouse gases concentration in the atmosphere. This phenomenon causes stronger interest in gas exchange measuring techniques such as eddy covariance, eddy accumulation and chambers. These techniques has been recently developed at Agromeotorology Department for water vapor, carbon dioxide, methane and nitrous dioxide exchange measurements. The measurements of CO2, CH4, N2O and heat fl uxes using described above techniques has been carried out at Rzecin wetland since the beginning of 2004. These activities have been realized in the framework of European integrated projects both CARBOEUROPE and NITROEUROPE.
