On the nitrogen budget for the United Kingdom and north‐west Europe
Tóm tắt
The application of a simple trajectory model approach to the emission, transformation and deposition of a coupled series of atmospheric pollutants including SO2, NOx and ammonia is described. A detailed comparison of the model results with observations is provided using United Kingdom monitoring data. Whilst reasonable agreement can justifiably be claimed for some species, whether in the gas phase, aerosol or precipitation, it is clear that for the others there are either severe disagreements or a lack of suitable data for comparison purposes. Background sources of these pollutants are assessed by applying wind sector analysis to precipitation measurements at remote sites. The budgets for the United Kingdom and north‐west Europe have a similar balance between wet and dry deposition to that given in the literature for the global nitrogen budget. This is in conflict with some literature budgets for Europe as a whole which have apparently overestimated the dry deposition terms.
