TFMM 7th Meeting, Helsinki, 10 – 12 May 2006 Decision of the Executive Body concerning the establishment a Task Force on the Hemispheric Transport of Air Pollution • The functions of the Task Force will be to: • develop a fuller understanding of the hemispheric transport of air pollution • estimate the hemispheric transport of specific air pollutants for the use in reviews of protocols to the Convention EMEP/MSC-E
TFMM 7th Meeting, Helsinki, 10 – 12 May 2006 The first meeting of the Task Force on Hemispheric Transport of Air Pollution (Brussels, 1-3 June, 2005) Overview of the state of the science • TF HTAP Policy-Relevant Science (Questions) • How does the intercontinental or hemispheric transport of air pollutants affect air pollution concentration or deposition levels in the Northern Hemisphere for ozone, PM, acidification and eutrophication; Hg; and POPs ? • What processes need to be better understood to describe the relative significance of intercontinental transport ? • What fraction of measured pollutant concentrations or deposition levels is due to emissions from each of the other countries in the Northern Hemisphere? . . . EMEP/MSC-E
TFMM 7th Meeting, Helsinki, 10 – 12 May 2006 The first meeting of the Task Force on Hemispheric Transport of Air Pollution (Brussels, 1-3 June, 2005) Future work • Observations • an integrated (virtual) data centre: observations from satellites, aircraft and surface measurements, including PM, ozone, Hg and POPs • Emissions • common database for emissions • Regional and global modelling • intercomparison of modelled source-receptor relationships EMEP/MSC-E
TFMM 7th Meeting, Helsinki, 10 – 12 May 2006 The second meeting of the Task Force on Hemispheric Transport of Air Pollution6 – 8 June 2006, Hotel “Mir”, Noviy Arbat 36/9, Moscow, Russia • Main agenda items: • Exploring the state of science related to • the intercontinental transport of POPs and Hg • the role of methane as a tropospheric ozone precursor. Recommendation of TFMM workshop on HM and POP model review:to extend the MSC-E models to the global scale EMEP/MSC-E

TFMM 7th Meeting, Helsinki, 10 – 12 May 2006 Conclusions • The input of hemispheric sources to the contamination of European region is considerable for Hg and some POPs. • External anthropogenic and re-emission sources is of importance for evaluation of source-receptor relationships for Hg and POPs in Europe. • Compatibility of model input data for hemispheric and regional modelling should be under consideration. • Close co-operation with and joint meeting of TFMM and TFHTAP on scientific and technical issues is highly appreciated.
