This Work Package will be done using available data from research infrastructures and advanced supersites from air quality monitoring networks, and by developing interoperable advanced instrumentation and tools. The selection criteria for the air quality metrics, including nanoparticle size distribution, particulate matter speciation, black carbon, volatile organic compounds, and their source contributions, will be based on combined air quality-aerosol-health effect science and the experience of the monitoring networks involved.
Taking full benefit from existing urban and regional supersite networks in and around certain urban environments and the existing ACTRIS network, we aim to develop novel, near-real-time data products on source identification and contribution for particulate material, including its major components, such as secondary organic aerosols, road dust, exhaust and non-exhaust emission, industry, airport and harbour contributions, biomass agricultural and domestic burning. At the same supersites, we will enhance observations, modelling and assessment for nanoparticles (<100nm), including proposing harmonised measurement protocols and size-segregated source contributions in urban areas, traffic sites, airports and harbours. ACTRIS experience and the involvement of AQUILA will be key components here.
