Abstract
The methodology of evaluating the exchange rates of CO2 and water vapor between vegetation and the atmosphere is presented. The two gases are measured with a short open path, fast responding infrared absorption gas analyzer. To determine the turbulent fluxes due to large scale eddies, high resolution wind measurements are obtained with a five-hole pressure sonde and a fast GPS (Global Positioning System) receiver. Measurements taken over Monte Bodone near Trento, Italy, a plateau in the Alps, are evaluated. The CO2 and water vapor budgets for the air layer above a few square kilometers were calculated and exchange rates for H2O and CO2 with the vegetation were estimated.
