1 Current State of PM-Monitoring in North Rhine-Westphalia Dr. Klaus Vogt Air Quality Monitoring Network State Agency for Nature, Environment and Consumer Protection of North Rhine – Westphalia (LANUV)

2 Vo 2 PMLAB _Heerlen Current State of PM10-Monitoring  A: Choice of PM measurement stations  B: Equipment – calibrations – future trends  C: Data aquisition – data handling  D: Spatial interpolation of point data  E: Forecast Modelling  LANUV is responsible for Air Quality Monitoring and Assessment throughout NRW

3 Vo 3 PMLAB _Heerlen  a bundle of aspects from different points of view A: Choice of Measurement Sites  Long term monitoring network  Legal requirements  Repetition measurements  External requests  Internet-Screening

4 Vo 4 PMLAB _Heerlen A1: Legal Aspects  Air Quality Directive 1999/30/EC – Federal Emission Law (BImSchG)  Air Quality Directive 2008/50/EC – national law in preparation  Minimum requirements, depending on zoning, population and lower/upper assessment thresholds

5 Vo 5 PMLAB _Heerlen Messorte in Gebieten PM10 (disko & konti) BallungsraumEWZ 07Ist 09 Aachen Bielefeld Dortmund Duisburg Krefeld Düsseldorf Essen-Bochum Hagen Köln-Bonn M.-Gladbach Münster Stolberg Wuppertal Warstein Rheinisches Braunkohlerevier Restgebiet Summe Zones and agglomerations established in NRW; minimum requirements for PM measurements

6 Vo 6 PMLAB _Heerlen Minumum requirement of sampling sites (Annex V, extract) a)Urban background and traffic:for NO 2, PM, CO, Benzene at least one station each b)Industrial sources: due to exposition and emission density, spatial distribution c)Ecosystems 1 per km² 1 per km² Measurement sites

7 Vo 7 PMLAB _Heerlen A2: Repetition Measurements 15 mobile containers (max. 2x2 m) within the network  Rotating principle with available ressources: First Measurements (Year 1) When exceedance of limit value: Air Quality Plan (Year 2-3) Measures (Year 3 ff) Controll Measurement (Year 4)  No longer feasible according to regulations in 2008/60/EC: immobilisation of measurement sites when exceeding limit values

8 Vo 8 PMLAB _Heerlen A3: External requests  Ministries (Environment, Economy, Health...)  5 Regional Governments in NRW (Köln, Düsseldorf...)  396 Municipalities (see below: Internet-Screening)  NGO´s  Citizen´s initiatives

9 Vo 9 PMLAB _Heerlen A4: Internet-Screening  Searching for suspicious traffic hot spots via a simplified dispersion modell  Cooperation with city agencies for environment via an internet tool  Basis for measurement request  Cities can find and calculate their own hot spots

10 Vo 10 PMLAB _Heerlen Air Quality Sreening NRW Searching for hot spots: Reduced modell tool (IMMIS web ) for cities via internet application (IMMIS dispersion modell by IVU Freiburg) Calculation of PM and other components in street canyons, using reduced data on traffic and building geometry

11 Vo 11 PMLAB _Heerlen Procedure for site planning and decision  Collecting and plausibility testing of ideas / requests / options /ressources  Inspection of preselected sites (problems, technical feasability...)  LANUV monitoring programme meeting in September  Report to Ministry and Regional Governments, asking for improvement proposals  Decisions in October  Preparation of measurement sites from October / January  Start of mesurement between and  Presentation of monitoring programme on internet

12 Vo 12 PMLAB _Heerlen The Monitoring Network in NRW 72 sites, including 15 traffic sites and 9 industrial hot spots in 2009 Main continuous measurements: - 64 x PM10 + PM x NO x SO x Ozone Main continuous measurements: - 42 x PM10 + PM x NO2 passive samplers (incl. metal and PAH analysis) stationtypes background forest industry traffic

14 Vo 14 PMLAB _Heerlen B: PM-Equipment – Calibration – Future Trends  Current Equipment: PM10: FH62 IR (14)TEOM SES (29) (101)TEOM FDMS (17)SHARP (5) Digitel DHA 80 (35)Derenda LVS3 (1) PM 2,5: TEOM FDMS (5)SHARP (6) (24)Leckel SEQ47/50 (12) Derenda LVS3 (1)  Trends: less devices: FH62 IR, DERENDA LVS3, TEOM FDMS more devices: Digitel DHA 80 safety reasons: PM2.5 AEI-Network gravimetric (ongoing testing in laboratory and field with SHARP and BAM)

15 Vo 15 PMLAB _Heerlen PM calibration procedure  Parallel measurement at 20 sites with gravimetric reference method and continuously measuring device  Yearly statistical analysis of all data in February (RIVM spreadsheet tests, calibration factors...)  Determination of calibration factors for different types of PM devices for the past year, using them as provisional factors for the ongoing year (sometimes individual factor for special sites) Example 2009: 1. TEOM-FDMS (B,C und CB): * Faktor 1,13 2. TEOM-SES: * Faktor 1,28 3. FH62: * Faktor 1,28 4. SHARP: * Faktor 1,06

20 Vo 20 PMLAB _Heerlen  EURAD-FLADIS NRW: a combination of modell results by EURAD (RIU Köln) with measurement data at background stations in the NRW monitoring network (LUQS) (“calibration of model results with measured data by data assimilation”)  analysis and vizualisation of spatial data for different components and years (status and prognosis)  Use as background data e.g. for the internetscreening (see above) D: Spatial Interpolation of PM point data

21 Vo 21 PMLAB _Heerlen E: Forecast modelling in NRW  EURAD Modell of RIU Köln: European Dispersion and Deposition Modell (used by UBA, NRW, BW)  Regional chemical aerosol transport model  nested, horizontal resolution up to 1 km x 1 km  four modules: meteorology (MM5), emissions (EE5), aerosols (MADE), chemistry (CTM)  Forecast of immission on regional scale  Ozone, SO 2, NO 2, PM, CO, Benzene  Additionally: modelling of annual averages  regional background values for, e.g., clean air plans N0: Europe 125 km x 125 km N1: Germany, 25 km x 25 km N2: NRW, 5 km x 5 km

22 Vo 22 PMLAB _Heerlen E: Forecast modelling in NRW, case studies (HERMINE) Sensitivity studies for contribution of emission sources to the background concentration of PM10, PM2.5, NO2 for 2006, with - actual emissions / basic case - no anthropogenic emissions in Germany - anthropogenic emissions only in NRW - no anthropogenic emissions in NRW - no gaseous emissions in NRW - no industrial emissions in NRW - no car emissions in NRW
