Local advection of NH3 over a pasture field

EMISSION, DISPERSION AND LOCAL DEPOSITION OF AMMONIA VOLATILISED FROM FARM BUILDINGS AND FOLLOWING THE APPLICATION OF CATTLE SLURRY TO GRASSLAND by RICHARD ALEXANDER HILL

EMISSION, DISPERSION AND LOCAL DEPOSITION OF AMMONIA VOLATILISED FROM FARM BUILDINGS AND FOLLOWING THE APPLICATION OF CA TILE SLURRY TO GRASSLAND RICHARD ALEXANDER HILL Emissions of ammonia (NH3) into the atmosphere, principally from agricultural sources, have been implicated in the pollution of forests, moorlands and grasslands, through the subsequent deposition of reduced nitrogen (NH,-N). Co...

Dry and wet deposition of inorganic nitrogen compounds to a tropical pasture site (Rondônia, Brazil)

The input of nitrogen (N) to ecosystems has increased dramatically over the past decades. While total (wet + dry) N deposition has been extensively determined in temperate regions, only very few data sets of N wet deposition exist for tropical ecosystems, and moreover, reliable experimental information about N dry deposition in tropical environments is lacking. In this study we estimate dry and...

Dynamics of ammonia exchange with cut grassland: synthesis of results and conclusions of the GRAMINAE Integrated Experiment

Improved data on biosphere-atmosphere exchange are fundamental to understanding the production and fate of ammonia (NH3) in the atmosphere. The GRAMINAE Integrated Experiment combined novel measurement and modelling approaches to provide the most comprehensive analysis of the interactions to date. Major intercomparisons of micrometeorological parameters and NH3 flux measurements using the aerod...

Using Weibull probability distribution to calibrate prevailing wind applying in oil spill simulation

In the Persian Gulf, the major source of oil pollution is related to the transportation of tankers, offshore production and discharges by coastal refineries. The water dynamical field has been obtained using a new hydrodynamic model. Local wind is recognized as the principal driving force combining to the water dynamic field to determine oil drift on the sea surface. The Weibull probability dis...
