GHG Europe


The nitrogen cycle and its influence on the European greenhouse gas balance

The NitroEurope IP – or NEU for short – addresses the major question: What is the effect of reactive nitrogen (Nr) supply on net greenhouse gas budgets for Europe?


The project’s objectives are to:

  • simulate observed fluxes of N and NGE, their interactions and responses to global change/land management decisions, through refinement of plot-scale models,
  • quantify multiple N and C fluxes for contrasting European landscapes, including interactions between farm-scale management, atmospheric and water dispersion, and consideration of the implications for net fluxes and strategies,
  • scale up Nr and NGE fluxes for terrestrial ecosystems to regional and European levels, considering spatial variability and allowing assessment of past, present and future changes,
  • assess uncertainties in the European model results and use these together with independent measurement/inverse modelling approaches for verification of European N2O and CH4 inventories and refinement of IPCC approaches.

These objectives are met by a programme that integrates:
1) An observing system for N fluxes & pools (Component 1)
2) A network of manipulation experiments (Component 2)
3) Plot-scale C-N modelling (Component 3)
4) Landscape analysis (Component 4)
5) European up-scaling (Component 5) and
6) Verification of European estimates (Component 6)

In addition to these, the project organisation comprises cross-cutting activities addressing management, databases, training and dissemination.
