2. 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

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?

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.
