Title: Use of EMEP results


1
Use of EMEP results in ICP MM assessments for
the support of the GP-revision
J-P Hettelingh, M Posch, J Slootweg ICP MM -
Coordination Centre for Effects
(CCE), www.icpmapping.org hosted at RIVM

Collaboration between EMEP and WGE-CCE includes
  • - emissions/depositions/concentrations from
    EMEP (CIAM MSC-W) for assessments of acid and
    nutrient exceedances in support of the revison of
    the gothenburg protocol and NEC (TSAP)
  • emissions/depositions from EMEP (MSC-E) for
    assessments of Heavy metal exceedances in support
    of effect based information to the revision of
    the HM protocol
  • Historic emission/deposition assessments for the
    dynamic modelling of changes to soil chemistry
    and vegetation diversity
  • Scenario specific information on various air
    pollution compounds for WGE expost assessments
  • Information on exceedances, land cover and soil
    chemistry for use by EMEP
  • Report and paper contributions

Area at N-risk of a more than 5 change in
biodiversity, i.e. of species richness
semi-natural grass lands s-alpine scrub
habitats, and similarity coniferous boreal
woodlands, together covering 53 of European
natural area

Assessment of the robustness of scenario impacts

Likeliness of Exceedances (AAE) in Europe based
on the ensemble of empirical and modelled CL(N)
Explore the inclusion of alternative deposition
assessments ?

In addition, some areas are also at risk
ofambient NH3 that exceed critical levels

PRI-2000
MFR-2020

Critical levels from Cape et al. 2008

Some concluding observations
  • Collaboration between EMEP and WGE-CCE
  • Works very well, including
  • science (FP7 publications reports) for ground
    truthing of
  • applications for the support of European air
    quality policies
  • Will review requirements to further implement the
    EB strategy calling for the broadening of the
    modelled system (change of climate and
    biodiversity uncertainty)
