1. NORTRIP NOn-exhaust Road TRaffic Induced Particle emissions - Development of tools for assessing the effect on air quality and exposure

3. Time & budget Time period – April 2010 – April 2011(?) Grant – Total for 2010: 510 000 DKK Salaries, meetings and travel costs – 60 000 DKK for DMU, SMHI, FMI, METROPOLIA, NILU, VTI, SLB, ITM – +30 000 DKK for ITM

4. Goals a more accurate, validated calculation model of non-exhaust (including road dust) emissions – better predictions of PM10 and PM2.5 concentrations and exposure – more accurate assessments of non-exhaust source contributions – more accurate evaluation of the effects of abatement strategies operational recommendations to local authorities on how to monitor and keep control of road dust emissions

5. Data SNIFFER EMMA eddy correlation of coarse particles laboratory road test data Statistical and source receptor analysis of the data – particle size distributions and size segregated (PM10, PM2.5 and PM1) trace metal concentrations

6. Models Dispersion and process modeling and validation of models and parameterizations Emission models developed by – SMHI – NILU OSPM dispersion model

7. Tasks 1. Organising the measurement database 2. Summarizing available model parameterisations 3. Organising and executing the validation excercises 4. Synthesis, reporting and recommendations

8. Time plan 0-6 months (May – Oct) – Task 1 & 2 6-12 months (Nov – April 2011) – Task 3 & 4

9. Own contributions ITM – 1) "Characterization of aerosols emitted from railway and road traffic – two important sources for peoples’ exposure in urban areas" which will provide characterization of road traffic particles (3.4 MSEK 2010-2012) NOT FUNDED – 2) "Traffic Emissions of Aerosols by Climate and Health Relevant Sizes" (TEACHERS) which will provide direct flux measurements of non-exhaust particles in Stockholm (3.2 MSEK 2010-2012) NOT FUNDED NILU & FMI – TRANSPHORM (EU project) SMHI & ITM – Mapping PM10 (SEPA) SMHI – Validation of SIMAIR model (SEPA) DMU – DMPS and soot measurements at 3 stations in Copenhagen (Miljöstyrelsen) FMI – MEGAPOLI (EU) Nordic Envicon & Metropolia – KAPU (national)

10. Outcome of this meeting New list of ongoing + other relevant projects/results List of expectations List of priority factors affecting PM10 New list of tasks – With dates of deliverables New time plan

11. Own contributions NEW New lists ITM – SRA: EMMA studies on Cement & Silent pavements SLB – Wetness, size distribution etc… FMI VTI SMHI DMU Metropolia NILU Nordic envicon

12. ITM EMMA data – Spatial/temporal variability Rural roads, motorways, city centre – Dependence on pavement Type, max stone size, cement – Dependence on speed – Dependence on tire type

13. Expected results Publication on – factors influencing PM10 – Governing processes – Quantification of the processes
