  1. PM correction factor in France Helène Marfaing (AIRPARIF) Olivier Le Bihan (INERIS) Français Mathe (Ecole des Mines de Douai) Laurence Rouïl (INERIS)

  2. Analysis of the results given by automatic and gravimetric methods

  3. Urban - Paris area Industrial - Normandy

  4. Metrological correction • FDMS correction kit : • equivalence with the gravimetric method (field campaigns : Paris, Le Havre, Marseille) • « automatic » measurement of the volatile fraction • real time correction • 50 “reference” sites equipped with TEOM/TEOM-FDMS devices • Determination of representative areas associated to these sites • The TEOM stations located in these areas are corrected following a near real time process by the observed difference [TEOM/FDMS-TEOM] at the reference site • Implemented since the 1st January 2007

  5. First feedback • A national working group involving the local associations in charge of air quality monitoring is still working hard : technical matters, interpretation, information to public and local authorities. • Test case : exceptional situation in spring 2007 (15th March- 15th April) • Occurrence of high PM episodes (100-130 ug/m3 (corrected), daily mean everywhere in France) • Episodes completely missed by the PREV’AIR forecasting system • Ammonium nitrate ? YES : 60-70 ug/m3 (15th March) -> influence of the high temperatures? Ammonia emissions from agriculture? • Forest fires in Russia? • Saharan dusts?

  6. Have you seen similar events in your own country? • Can the TFMM be a network supporting exchange of such experiences? • EMEP field campaign in spring or early spring 2009?
