Progress in EMEP 2016-2017 workplan: Measurements and modelling Added value of Twin urban regional/remote Supersites to LRT contribution to urban AP
Extended Bureaux EMEP & WGE, Geneva March 21th 2017

Slide3Candidate SitesSpain: (done)Barcelona (UB), Montseny (RB),
Montsec (Mountain) > 7 years of data available Full chemical speciation availableSwitzerland (in progress)
Zurich-Kaserne (urban background), Rigi-Seebodenalp (rural).2 years of data available (not continuous)Full chemical speciation availableFrance (planned)Revin (rural), Lens (urban background), Roubaix (traffic) 1.5 years of data available
Full chemical speciation available
United Kingdom (not possible yet)
London: Marylebone Road (roadside), London, North Kensington (urban background) and Harwell (rural);
Chemical
speciated data at RURAL site for 2016 not yet availableNo trace elements at UB site (minor PM sources not detectable)Sweden (not possible)
Stockholm: Hornsgatan – street; Torkel knutssonsgatan – urban background; Aspvreten – ruralOnly short measurement campaigns;At RB site only SIA and OC/EC available ; Thus only Traffic and UB sites available for PMF application
