  1. The siginficance of organic compounds for the nitrogen deposition in the Netherlands

    In the Netherlands, nearly all wet nitrogen deposition occurs in the form of ammonium and nitrate. Such is the main conclusion from a study of non-routinely measured forms of nitrogen in...

  2. Global assessment of nitrogen deposition effects on terrestrial plant diversity: a synthesis

    Atmospheric nitrogen (N) deposition is a recognized threat to plant diversity in temperate and northern parts of Europe and North America. This paper assesses evidence from field experiments for N...

  3. Regionale modellering van fijn stof voor Nederland

    Dit rapport is een technisch achtergrond rapport over het modelleren van fijn stof. Voor het beleid is het noodzakelijk om de relatie tussen emissies, atmosferische omstandigheden en de...

  4. Regional modelling of particulate matter for the Netherlands

    The natural contribution to particulate matter (PM) can now be calculated with a model for PM. Therefore, the LOTOS EUROS model was extended with a description of PM from sea salt and mineral dust...

  5. The LOTOS-EUROS model: description, validation and latest developments

    This paper presents a validation study for oxidants and secondary inorganic aerosols using the new regional Chemistry Transport Model (CTM) Long Term Ozone Simulation (LOTOS) European Operational...

  6. What is reactive nitrogen (Nr)?

    Reactive N (Nr) includes all biologically, photochemically and radiatively active N compounds in the earth’s atmosphere and biosphere. In other words, Nr includes: inorganic reduced forms of N (e.g. ammonia [NH 3 ] and ammonium [NH 4 + ]); inorganic oxidized forms (e.g. nitrogen oxide [NO x ...
  7. The VELD experiment: An evaluation of the ammonia emissions and concentrations in an agricultural area

    From July 2002 until September 2003, a detailed ammonia emission inventory was carried out in concurrence with detailed measurements of the ammonia concentrations in air in a 3 × 3 km area in the...

  8. European wet deposition maps based on measurements

    To date, wet deposition maps on a European scale have been based on long-range transport model results. For most components wet deposition maps based on measurements are only available on national...

  9. Wat is potentieel zuur?

    atmosfeer werkt ammoniak zuurneutraliserend. Komt ammoniak (of het omzettingsproduct ammonium) echter in de ...
  10. Natte depositie kaarten van Europa gebaseerd op metingen

    Natte depositie kaarten van Europa zijn tot nu toe gebaseerd op modelresultaten. Kaarten die op metingen zijn gebaseerd zijn voor de meeste componenten slechts op nationale schaal beschikbaar....
