Surface conductance and energy exchange in an intensively managed peat pasture
Aerodynamic measurements of latent (λE) and sensible heat (H) exchange were made in an intensively managed peat pasture during 2 consecutive years; the fetch was approximately 1.5 km. The surface conductance (gs) was calculated from the Penman-Monteith equation. The analysis focused on 2 successive aspects of gs: gs as a function of environment (primarily vapour pressure deficit [D]) and the en...
متن کاملEffect of drainage on CO2 exchange patterns in an intensively managed peat pasture
Eddy correlation measurements of CO2 exchange (F) were made in intensively managed peat pastures at 2 different groundwater tables during most of a growing season. F was separated into a respiratory (Fr) and an assimilatory (Fa) CO2 flux. The fit of the Arrhenius temperature response to Fr showed that Fr was generally higher at low groundwater tables. The fit of a hyperbolic irradiance response...
متن کاملYearly follow-up of methane turbulent exchange over an intensively grazed pasture in Belgium.
Methane emissions account for 8 % of the EU-15 GHG emissions and livestock generates 40 % of these emissions (European Commission, 2009). These fluxes are mainly measured in metabolic chambers with the drawback of bringing the cattle in an unfamiliar environment. Recent technological advances in spectroscopy now permit methane flux measurement using eddy covariance. This micrometeorological met...
