  1. Testbed in Division of Atmospheric Sciences point of view Markku Kulmala University of Helsinki Department of Physical Sciences

  2. Division of Atmospheric Sciences • ca. 70 scientists • 7 professors • aerosol and environmental physics • micrometeorology and chemical meteorology • dynamic and physical meteorology • e.g. • mesometeorology • radar meteorology

  3. Centers of Excellency APFE Finnish Academy of Finland Nordic BACCI, Aerosols Nordic, NECC,Fluxes NordForsk Graduate School CBACCI ENoE ACCENT iLEAPS/ IGBP CARBOEUROPE, NITROEUROPE EUCAARI, EUSAAR

  4. Approaches: how to answer our research questions • experimental • laboratory • field (continuous and campaigns) • development of novel instrumental techniques • theoretical • basic theories • simulations • model development • From molecular to global scale • Physics, Chemistry, Biology, Meteorology • Inter- and multidisciplinary approaches • Global networking and partnership

  5. Research Chain • Molecular properties • Nucleation • Aerosol Dynamics • Boundary Layer Dynamics • Regional Scale • Global Scale • COSMOS consortium

  6. EUCAARI measurement network

  7. Continuous Measurements

  8. Observation of Nucleation Burst in Finland Cloud Condensation Nuclei Aerosol particles Cluster Ions Kulmala et al., 2004, ACP

  9. New CoE: Ambition

  10. Future ideas • MesoMet as part of Centre of Excellence (European Centre of Atmospheric Reserach) • Needs to use Testbed for trace gas and aerosol research • Pollution episodes • Atmospheric chemistry • Aerosol dynamics

  11. Visions 2025 • More environmental related measurements with continuous datasets • CO2 from 1958 (Mauna Loa) • Aerosol size distributions from 1996 (Hyytiälä) • Models with more exact chemistry and aerosol dynamics • pollution, health effects • climate change • However, a lot to study still left • comparison met. studies started around 150-200 years ago • environmental studies ca 20-50 years ago
