  1. European Initiatives on Nitrogen Several new initiatives proposed New Cluster: European Transboundary Nitrogen Activity (ETNA)

  2. UNEP CBD SEBI 2010

  3. COST 729: • Assessing and managing nitrogen fluxes in the atmosphere-biosphere in Europe, • Chair: Jan Willem Erisman • Alternate Chair: Peringe Grennfelt • Started March 2005.

  4. ESF Nitrogen Project • Nitrogen in Europe: Assessment of current problems and future solutions • Jan Willem Erisman, Albert Bleeker ECN. • Scientifically approved, now collecting national ratifications • Close link to the INI assessment

  5. Proposed FP6 Integrated Project: NitroEurope IP

  6. NEU Flux &ManipulationNetworks 15 Level 3 Super Sites 8 Level 2 Regional Sites 50 Level 1 Inferential Sites 22 Core Manipulation Sites 14 Assoc. Manipulation Sites

  7. NEU Flux Network Sites in relation to EMEP network • Level 3: N and GHG fluxes: Core Measurements + Special Topics. Includes high cost micromet methods and process analysis. • Level 2: Basic N and GHG flux monitoring, e.g. COTAG, simple cuvettes • Level 1: Basic N air concentration measurements at 50 CO2 flux sites. e.g. DELTA low cost denuders.
