8. EUSAAR Intercalibration Exercises (2007 and 2008). Main Results
OC/EC (J. –P. Putaud, JRC): Round-Robin intercomparison and development of artefact free sampler
Intercomparison of identical filters from several EUSAAR sites operating operating with similar thermo-optical methods
Need for homogeneizing methods (even if there is no best method) Converging towards a EUSAAR method for thermal-optical methods
Sampling strategy is also address to account for the Impact of volatile Organic compounds on TC measurements
TFMM, April, Bordeaux, France

9. EUSAAR Intercalibration Exercises (2007 and 2008). Main Results
Size distribution (A. Wiedensohler, IFT): intercalibration and improvement of SMPS.
34 CPCs (12 different models) and 16 SMPS were checked and calibrated
Intercalibration clearly needed. High variability in terms of total number and size
Improvement when using standard retrieval procedures
Additional work to improve use of commercial instruments for monitoring operation in specific conditions
Development of additional SMPS for Montseny, Kosetice and Finokalia
TFMM, April, Bordeaux, France

10. EUSAAR Intercalibration Exercises (2007 and 2008). Main Results
Optical properties (A. Wiedensohler, IFT) :intercalibration of absorption/scattering coefficient instruments and corrective procedures.
Large variability amongst abs. Coef. Measuring instruments.
Avoid the use of BC but rather limit the interpretation to abs. Coeff.
MAAP appears as the most suited instruments. Correction is needed for aethalometers
Variability of nephelemeters also significant
TFMM, April, Bordeaux, France

11. EUSAAR Intercalibration Exercises (2007 and 2008). Main Results
Hygroscopic Properties (U. Baltensperger, PSI): Develop and cross-calibrate monitoring HTDMA
11 instruments prepared according to common conceipt. Will be used for EUCAARI campaigns by PSI, SU, CNRS, ICPF, UHEL, FMI, UIG, JRC, IFT
Common Routine inversion procedures prepared by PSI
Key variable for chemistry – transport simulation
TFMM, April, Bordeaux, France

12. EUSAAR Intercalibration Exercises (2007 and 2008). Main Results
Nanoparticle size distribution (M. Kulmala/Pasi Aalto, UHEL): Intercalibrate particle/cluster/ion size distribution below 10 nm
SMPS size range can be extented down to 5nm on a routine basis
AIS (and NAIS/BSMA) provide a very useful complement to classical SMPS for nanoparticle monitoring
Successful intercomparison of 10 AIS available in Europe
AIS deployed within EUCAARI at several sites
TFMM, April, Bordeaux, France

13. EUSAAR data base and sampling quality
1- Use common formatting procedures for data diffusion (NASA- AMES)
2- Data transferred to NILU/EUSAAR/EBAS data base according to submission protocol similar to EMEP (2006 data already submitted)
3- Automatic link to WDCA in JRC
In addition
4- Hold regular audits of EUSAAR stations (instrument and personnel) – Audits highlight the need for regular inspection of sampling procedure and instrument maintenance
5- Hold regular aerosol courses for EUSAAR partners and associates

18. IOP 2008-2009: instrumental deployment
3 intensive campaigns are scheduled in 2008 EUCAARI (May) in Cabauw and Finokalia, SPC (March), EMEP (Sept-October 08) and EMEP (February09).
EMEP sites not necessarily identical to EUCAARI/EUSAAR sites
Additional HTDMA measurements at selected sites (SPC, FInokalia) concentrations needed at some sites
AMS measurements will be performed but not enough instruments available – Some MARGA deployed as well.
LIDAR information when available

22. EUSAAR/ EMEP / EUCAARI synergies: recommendations
EUSAAR provides measurements of aerosol variables in addition to standard EMEP.
Additional measurements during IOP are provided through the EUCAARI program (both long-term and campaigns)
EMEP campaign scheduled Sept. 08 and Feb. 09 provide the opportunity to make the a reference year for future modelling activities in Europe.
Only a few necessary measurements are covered under the EUSAAR/EUCAARI projects. Additional participation from funding agencies in the member states clearly necessary.
ACCENT/EUSAAR may provide additional funding but expect competition for that call (i.e. first call of 2007 : 300 k€ requested and 60 k€ distributed), second call is opened
TFMM, April, Bordeaux, France

23. EUSAAR/ EMEP / EUCAARI synergies: recommendations
Important recommendation for efficient use of the measurements:
For advanced aerosol variables, there is a clear need for intercalibration exercises before use in joint operation (standard QA/QC and analytical procedures for EMEP/EUCAARI/EUSAAR)
There is a need for an integrated aerosol data base (standard data formatting)
Favour co-location of gas/aerosol measurements at supersites over spreading the effort over too many not so well instrumented stations.
Additional effort to non-EUSAAR partners but key requirements
