Estimation of NH3 emissions from a naturally ventilated livestock farm using local-scale atmospheric dispersion modelling
NH3 a naturally ventilated livestock farm local-scale atmospheric dispersion modelling
2010/1/21
Agricultural livestock represents the main source of ammonia (NH3) in Europe. In recent years, reduction policies have been applied to reduce NH3 emissions. In order to estimate the impacts of these p...
SURFATM-NH3:a model combining the surface energy balance and bi-directional exchanges of ammonia applied at the field scale
SURFATM-NH3 surface energy balance bi-directional exchanges ammonia field scale
2010/1/20
A new biophysical model SURFATM-NH3, simulating the ammonia (NH3) exchange between terrestrial ecosystems and the atmosphere is presented. SURFATM-NH3 consists of two coupled models: (i) an energy bud...
Advection of NH3 over a pasture field and its effect on gradient flux measurements
Advection NH3 pasture field gradient flux measurements
2010/1/20
Deposition of atmospheric ammonia (NH3) to semi-natural ecosystems leads to serious adverse effects, such as acidification and eutrophication. A step in quantifying such effects is the measurement of ...
The relationship between NH3 emissions from a poultry farm and soil NO and N2O fluxes from a downwind forest
NH3 emissions poultry farm soil NO N2O fluxes downwind forest
2010/1/13
Intensive livestock farms emit large concentrations of NH3, most of which is deposited very close to the source. The presence of trees enhances the deposition. Rates to downwind forests can exceed 40 ...
