Fluxes and trends of nitrogen and sulphur compounds At integrated monitoring sites in Europe

摘要

The International Cooperative programme on Integrated Monitoring (ICP IM) is part of the effects monitoring strategy of the UN/ECE Convention on Long-Range Transboundary Air Pollution. We calculated input-output budgets and trends of N and S compounds, base cations and hydrogen ions For 22 forested ICP IM catchments/plots across Europe. The site-specific trends were calculated for Deposition and runoff water fluxes an concentrations using monthly data and non-parametric methods.
