  1. Souad Bouallala Patrick Tisserant ADEME (French environment and Energy management Agency) Air quality monitoring department AIR QUALITY DATA FLOWS IN FRANCE

  2. AQ monitoring, who does what ? NATIONALLEVEL Ministry of Environment (MEDD) ADEME (general monitoring policy)(Technicalcoordination National Data Base Research Programmes) National AQ monitoring Laboratory LCSQA (technical support : metrology, modeling and quality assurance) LOCAL LEVEL 40 Air Quality Monitoring Entities (AQME) ( local implementation of monitoring, information...)

  3. Air quality monitoring system 40 local air quality monitoring network entities ~700 monitoring stations, 2 500 monitoring devices Their mission: • to measure • to forecast • to inform (web, local authorities) They measure everyday : • regulated pollutants (SO2, NO2, O3, PM10, Pb, benzene, CO) • «new» pollutants (heavy metals, PAH, PM2.5, VOC, …)

  4. Operational QA/QC procedures in AQME 1/ National calibration chain National reference standards (level 1) Regional reference standards (7 ) (level 2) Stations working standards (level 3) Transfer standards 1->2 and 2->3 SO2, NO-NO2, O3, CO, benzene

  5. Operational QA/QC procedures in AQME 2/ Validation of data 1 - Automatic prevalidation 2 - Technical validation 3 – Environmental survey validation Processed data Extract from guideline « rules and recommandations of AQ data »

  6. Air quality data flow chart 700 monitoring stations 32 regional servers national database 40 local monitoring network managing entities O3 NO2 SO2 PM10 PM2.5 BTX Iso files day ADEME National Information data exchange with the EEA and the EU AQME web sites National web site NATIONAL LOCAL

  7. The National air quality database in France Objectives : • Data exchange with EEA • Air quality report and assistance in decision making • Scientific research • epidemiology studies, • model validation • Saving data of local network

  8. AQDBusers in France • MEDD/IFEN, Ecole des mines de Douai INERIS, CNRS, AFSSE, INVS, INRA, Météo-France, LHVP, APPA, DRASS… • PREVAIR • Research laboratories : physico-chimistry, climate science, epidemiology • EEA, WHO, Joint Research Centre

  9. Pollutants in AQDB Since 1985 (automatic data): • SO2, NO-NO2-NOx, O3, CO • particules (PM2.5), (PM10) (TSP) • Benzene,Toluène, o,m & p Xylene Each year about 20 millions hourly data (and 80 millions ¼ hourly data) For 2005: “manual” data • PAH (BaP), heavy metal : Cd, As, Ni, Hg, Pb • VOC, Precipitations

  10. Number of data (representativity rate ) Mean (hourly, 8h, daily, mensually, annually) Percentiles (50, 98, 99,9) sur 1h, 24h Number of mean > value Number of days > value Number of exceedences AOT forest and vegetation The available statistics on the AQDB Available on www.atmonet.org

  11. How air quality information is managing in national level ? • Air quality data store in the national database • Exporting data procedures • Quality procedures in AQDB

  12. Air quality data store in the national database Hourly data (non validated) BASTER (NRT+3h) ISO V1.7 Hourly data Automatic VOC CSV Multi-timing data Manual data XML BDATMO Informix BULDAIR Mysql BASTER Informix Quarter hourly data AQDB ISO V1.7 Daily data AQ index Text file
