  1. Synergies between EMEP and EUSAAR Wenche Aas and Kjetil Tørseth EMEP/CCC (NILU)

  2. UN-ECE Convention on Long-Range Transboundary Air Pollution ( 49 Parties) - 8 Specific protocols, where the first isEuropean Monitoring and Evaluation Programme (EMEP) (41 Parties) • EMEP Topics • Acidification and Eutrophication • Photochemical oxidants • Heavy metals • Persistent Organic Pollutants • Particulate matter The EMEP vision; To be the main science based and policy-driven instrument for international cooperation in atmospheric monitoring and modelling activities, emission inventories and projections, and integrated assessment to help solve transboundary air pollution problems in Europe

  3. Monitoring programme: • Level 1 • Main ions in precipitation and in air • heavy metals in precipitations • ozone • PM10 and PM2.5 mass • meteorology • at ca 125 sites • Level 2, supersite • POPs • Heavy metals in air and aerosols • VOC • EC/OC, OC speciation • Mineral Dust • PM speciation incl. gas particle ratio • + all level 1 activities • 15-20 sites

  4. Level 3 Develop the scientific understanding of the relevant physico-chemical processes • Research driven • May often be available at locations other than level-1 and level-2 sites • Data would typically be provided by other institutions than those being responsible for implementing the national monitoring obligations • A number of relevant parameters are identified as being of interest for EMEP • Level-3 sites may include campaign data

  5. Monitoring programme, Level 3

  6. Why EMEP needs these measurements • Large knowledge gaps on : • composition • sources • process understanding (e.g particle formation) • Transport and vertical profiles • All needed for model evaluation and development In addition, known quality and completeness (i.e supersites) is essential

  7. PM10, EMEP model/measurements, 2003 Excl water and mineral dust Incl water and mineral dust EMEP model EMEP model EMEP obs EMEP obs EMEP status report 4/2004: a proper validation concerning the models performance regarding the aerosols content of mineral dust and particle water is hampered by insufficient measurements. Thus, the calculated concentrations for dust and particle water are still rather uncertain.

  8. PM10 and PM2.5 composition in Spain mg/m3 “There is a considerable underestimation of measured concentrations of total carbon by the model, which is expected to be improved when SOA is introduces in the EMEP Unified model.“

  9. Measurements for model evaluation From EC/OC EMEP campaign:

  10. Quality assurance • Standardized sampling procedures (N2,N3,N4) generated by the NAs will be adopted and included in the EMEP Manual and presented for the Task Force of Measurements and Modelling (TFMM). • Define data quality objectives (N2,N3,N4) and organise instrument comparisons in connection with other national and international programmes such as EMEP and GAW. • Audits and capacity building (N6) Auditing sampling protocols at infrastructures, promote good practices and diffusion of knowledge through workshops and training courses (joint with EMEP / GAW activities) QA/QC is a key element for EMEP/CCC. Harmonised QA between research and monitoring programmes are essential

  11. Data submission, database and dissemination • Builds on the work done in the CREATE project where EMEP and GAW harmonised their dataflow. • A few steps further (N5): • Include other parameters • Harmonised data submission, defining new protocols etc • Improved access to user specified data • Better statistical and graphical tools

  12. EMEP for EUSAAR • Direct link to policy • EMEP/CCC infrastructure of database, QA procedures and protocols and reporting will be used and developed • The results presented at the task force of measurements and modelling (TFMM) • Ensure sustainability • Many of the participating institutions and the sites are already part of the EMEP programme, hence need to fulfil the monitoring strategy • Data produced will immediately be used to develop the EMEP model.

  13. Support letter from the Chairman, Jürgen Schneider, of the EMEP Steering Body .. while with Level 3, we strongly depend on collaboration with research projects… Obviously, the activities proposed under EUSAAR would be an important step forward in implementation of the new monitoring strategy and would help that EMEP will also comply with its challenges and goals in the future.
