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, 23-25 April, Bordeaux, France

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, 23-25 April, Bordeaux, France

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, 23-25 April, Bordeaux, France

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, 23-25 April, Bordeaux, France

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, 23-25 April, Bordeaux, France

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 List all deliverables. TFMM, 23-25 April, Bordeaux, France

EUCAARI : Objectives within Element 2 (Regional Air pollution) Quantify the contributions of different anthropogenic and natural sources to the PM10, PM2.5, and ultrafine particle concentrations. provide new information on particle hygroscopicity and composition, along with the source apportionment estimate the hygroscopic evolution and loading due to long-range transport. contribute to the validation of both process-models and regional AQ models List all deliverables.

IOP 2008-2009: instrumental deployment 1 - Year round measurements (May 2008- May 2009): Measurements performed within EUSAAR : size distribution, bulk chemistry (OC/EC, Inorganic), optical properties Year round measurements with EUSAAR-HTDMAs:– 10 instruments will be ready by the beginning of 2008 Additional CCN concentrations needed at some sites. How many CCNC are available still a question (3/4) Additional AIS measurements (11 instruments) List all deliverables. TFMM, 23-25 April, Bordeaux, France

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.

EUSAAR/ EMEP / EUCAARI synergies: recommendations EUSAAR provides measurements of aerosol variables in addition to standard EMEP. Additional measurements during 2008-2009 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 2008-2009 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, 23-25 April, Bordeaux, France

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 TFMM, 23-25 April, Bordeaux, France

EUSAAR/ EMEP / EUCAARI synergies: recommendations Thank you for the attention TFMM, 23-25 April, Bordeaux, France
