  1. Photooxidants and particles:Addressing hemispheric issues from Europe Frode Stordal and Øystein Hov Norwegian Institute for Air Research (NILU) Ivar S.A. Isaksen, University of Oslo Presented at the PPH Arctic - North Atlantic Workshop CIESIN, Palisades, New York, June 12 - 15, 2001

  2. EMEP: Role and contribution in hemispheric studies • Background issues • Current observations • Relation to regional and global networks • Hemispheric aspects: extension of data basis

  3. EMEP: Background issues • Monitoring of key species • Reasonable coverage in Europe • About 20 years experience • Strongly linked to policy development • Strong QA/QC procedures • Common database • National commitment to the programme • Towards integration with the EU regulatory requirements

  4. Towards hemispheric monitoring:Necessary and possible extension of data basis • Spatial coverage of observations • Theoretical analyses

  5. Towards hemispheric monitoring:Spatial coverage of observations • Sondes • Aircraft • Remote sensing, ground based • Remote sensing, satellites

  6. Towards hemispheric monitoring:Theoretical analyses • Hemispheric and global models • Data assimilation

  7. Towards hemispheric monitoring:EMEP contributions • EMEP’s network well suited as a regional component • Wishes to extend focus to the hemispheric scale • Wants to adapt to this new challenge • Will contribute to strategic planning • Open to advice on how to act as a responsible player
