  1. Data Files Structure LAT Lab Is there an additional level of data necessary (Volvo proposal)? Volvo/LAT

  2. February 2003 • LD: EMPA • HD: VTT, AVL, TUG • First release of test data • We received nothing • March 2003 • LD: Shell • HD: Volvo, TUG, MTC • Second release of test data • We received nothing • April 2003 • First release of Consolidated Test Data • LD: MTC, IFP, LAT • Third release of test data • We received HD from VTT, AVL • May 2003 • Second release of Consolidated Data (May, 9) • LD: Inrets • HD: Volvo (addit.) • Final release of test data (wk 21 – May 23) • End of May: Cut-off of data submission Data Submission Progress I

  3. However things are not as bad as the previous slide indicated. We are in contact with most of the partners and we know what the situation is • Status of progress • AVL: already sent 1st release • VTT: already sent 1st release • TUG: in progress: work on files • VOLVO: done w. measurements, work on files • LAT: Still measuring and producing files • EMPA: done w. measurements, work on files • Shell: diesels done, complete gas. by end of May, working with files • MTC: work on files? • IFP: ? • INRETS, AEAT Data Submission Progress II

  4. Individual labs: • Send any data by May, 9. • FINAL DATE FOR SUBMISSION REMAINS MAY, 30. Drafts of lab reports should be ready by May, 30. • Co-ordinator: • Prepare database (1st consolidated data version) and circulate it immediately(May, 12). Steps Ahead

  5. Focal points (Concawe, Volvo, TUT, EMPA) receive: • 1st consolidated version (CV) May, 12 • 2nd CV June, 6 • Key elements of evaluation: • Confirmation of adequacy of QA/QC (Concawe, Volvo). Wet/dry branch comparisons (TUT). • Identification of outliers (Concawe, Volvo) • Statistical evaluation (2nd CV) • Follow-up based on 1, 2 (LAT) • Indicative evaluation by May, 30 (1st CV). Final evaluation by June, 30 (2nd CV). • Definition of standardised representation of consolidated data for D11-D14 by May, 30. (LWA) Consolidated Data Evaluation

  6. Introduction • Health effects • One Chapter per Deliverable • D2: Instruments • D3: Sampling • D7: Road-side measurements • D8: Non-exhaust • D11: Current vehicles • D13: “Anticipated” technologies • D12: Off-cycle • D14: Fuel effects • Validation of measurements (Ford) • D15: Relevance of current PM emission standards and further aspects • Summary & Conclusions Final Report Structure 1st draft by July 15 latest to LWA/LAT

  7. Sampling • CVS • MDSs • Practices / Recommendations • PMP-Relevant Questions • Where do we go from mass • How much can mass measurement be improved • Which are alternative particle properties • Number • Size • Surface • Chemistry • Relevance of nuclei mode • Is it necessary to measure • Can it be measured accurately with repeatability • Is it an artefact with no relevance to the atmosphere Which are the main (unanswered) relevant questions in the scientific community?
