The emission of the greenhouse gas (GHG), nitrous oxide (N2O) from human activities are contributing to global climate change. An estimated 29% of Ireland's GHG emissions are from the agricultural sector and N2O make half of these. The Intergovernmental Panel on Climate Change (IPCC) has prescribed limits on national GHG emissions and provides a method for estimation derived from IPCC ¿Tier l¿ which may be an overestimate. Therefore Irish Agriculture requires an accurate estimation of N2O in order to avoid overestimation in future. N2O emissions are being measured at eight grassland different sites in South Ireland over a period of 2 years. The main site is Dripsey (Co, Cork) and the emissions are being measured both by eddy covariance and chambers. The other seven sites are spatially dispersed throughout the south western region to represent the most prevalent soil properties and grassland management practices. This approach will capture both temporal variation at the main site and spatial variation at the seven satellite sites. This project aims for an improved understanding of N2O emissions controlling parameters, its spatial and temporal variation and a robust estimate of N2O emission.
